Types of Stainless Steel

So  let's see one by one each of which type of Stainless Steel for first we will see something about stainless steel so here when nickel is added in the steel, for instance, the austenite structure of iron is stabilized okay this crystal structure makes such steels virtually non-magnetic and less brittle at low temperatures for greater hardness and strength more carbon is added with proper heat treatment these steels are used for razor blades cutlery too and tools significant quantities of manganese have been used in many stainless steel compositions Magnus preserves an austenitic structure in the steel at a low cost than nickel stainless steels are also classified by their crystalline structure.

There are five types of stainless steel :
  • Austenitic stainless steels
  • Ferritic stainless steels
  • Martensitic stainless steels
  • Precipitation hardening
  • Duplex stainless steel

1. Austenitic Stainless Steels 

These stainless steels make up over 70% of the total stainless steel production these tails are non-magnetic, these steels outstanding stainless steels are non-magnetic in annealed conditions they cannot be hardened by heat treatment they can be hot worked or cold worked they contain a maximum of 0.15 carbon a minimum of 16% chromium and sufficient nickel and manganese to retain an austenite structure at all temperatures from the cryogenic region to the melting point of the alloy these steels are specified as AISI 202, 302, 304,  316, 321, etc. They are non-magnetic soft ductile malleable in character the corrosion resistance of this group of steels is superior to ferritic and martensitic stainless steels these steels are used for food and chemical plants tubular exchangers sanitary fittings aircraft heaters domestic and industrial utensils.

2. Ferritic Stainless Steels

These are plain chromium stainless steels with varying chromium content between 11% and 18% but with low carbon 0.08 to 0.2 contained they have a moderate good corrosion resistance okay moderate good corrosion resistance ferritic stainless steels have these steels are not hard enabled by heat treatment by martensitic transformation due to the absence of austenite phase okay at any temperature the only annealing heat treatment is suitable for ferritic stainless steel so only annealing hate treatment these stills can be moderately hardened by cold working the stills are specified as AISI four zero five four three zero and four four six they are magnetic soft ductile malleable in character these tails are widely used for furnace parts food industries especially pressure wheezes heaters use carrying pipes in sugar industries pots and pans.

3. Martensitic Stainless Steels

Martensitic stainless steels are commercially developed for cutlery purpose they are plain chromium steels containing between 12 to 18% chromium high carbon content to 0.1 to 1.2% compared to other grades of stainless steels the stainless steel is of your friends it has moderate corrosion resistance, moderate corrosion resistance which can be hardened by heat treatment resulting in high strength and hardness, it has poor weldability. It is martensitic stainless steel is a magnetic on these steels are specified as AISI four 403, 410, 416, 420, 501, and 502. It is commonly used for knife blades surgical instruments shafts turbine blades paper machinery parts spindles and pins.

4. Precipitation hardening Stainless Steels 

Precipitation hardening stainless steels are iron nickel-chromium alloys containing one or more precipitation hardening element such as aluminum titanium copper niobic mend molybdenum the precipitation hardening is achieved by the relatively simple aging treatment is used for precipitation hardening here friends of the fabricated part the two main characteristics of all precipitation hardening stainless steels are high strength and high corrosion resistance high strength is achieved at the expense of toughness the corrosion resistance of precipitation hardening stainless steels is comparable to that of the standard AISI 304 and AISI 316 austenitic alloys.
Now the aging treatments redesigned here to optimize the strong corrosion resistance and toughness, further to improve toughness the amount of carbon is kept low the precipitation hardening processing valves the formation precipitation of very fine intermetallic carbides prolonged aging causes the coarsening of these intermetallic phases which in turn causes the decline in strength due to the fact that dislocations can bypass cores intermetallic phases these stills used for bulkheads nibs skins and other structural parts.

5. Duplex Stainless Steels

These steels contain relatively highchromium18 to 28% and moderate amounts of Nickel 4.5 to 8% the Nickel content is insufficient to generate a fully or genetic structure and the resulting combination of austenitic structure is called duplex okay the combination of ferreting and austenitic structure is called here duplex most duplex trees contain molybdenum in a range of 2.5 to 4% these have a high resistance to stress corrosion cracking and chloride iron attacks they have a higher tensile and ill strength than austenitic of hypotonic steels as well as good weldability and formability they are commonly used in marine applications discharge desalination plants heat exchangers and petrochemical plant.

Beginner Guide: How to Install Tube Fittings Properly

So you want to install tube fittings, In this article, I will explain to you that how to connect tube fittings otherwise known as compression fittings accurately and securely.

Every time to make sure it's safe for you and your workers before we install a tube fitting we want to make sure that the tube is properly prepared, So we want to make sure it's clean that it's deburred and that the tubing harness matches the tube fitting specifications always check with your manufacturer to make sure your tubing is certified to work with the tube fitting that you happen to be using there is one big myth that is common in the industry and that's when we're tightening the tube fitting that a two fitting can be tightened and it's a matter of torque.

So, Did we get the torque right?

Did we tighten it up and Can we feel when the torque is right and know that a fitting is tightened correctly?

Stainless Steel Tube Fittings Manufacturer, Supplier and Exporter in India

Big myth and big misunderstanding, in reality, a tube fitting nut is tightened on the stainless steel tubing by the depth that the nut is tightened to or a number of turns from hand tight today I want to tell you how to tighten a tube fitting properly on the tubing, So we make sure to have a leak-free safe connection every time there are standard guidelines for installing virtually every tube fitting on the market and they're all the same no matter what brand of all the major brands in the market piece of tubing is inserted into a tube fitting until it bottoms out there's a shouldering the back of it that we're going to bottom this tube fitting out on it's very important than we're going to take the nut and we're going to hand tighten the nut until we can't hand tighten any more at that point a marker is needed. We will mark the nut at the six o'clock position along with the body with your marks at the six o'clock position. We will continue to rotate this nut with a wrench one and one quarter turns from hand tight six o'clock position.

One and one quarter turns brings it to the nine o'clock position and that's it that's as easy as installing a tube fitting is but there's one other thing that we have to do which I see in the market that not many people do every manufacturer has in their instructions that after a two-fitting is installed we must then use the gap gauge to check the gap between the nut and the body.

So there may be a gap when we finish tightening this nut correctly there's only one spot that will give us the maximum sealing potential for a safe and sure connection under-tightening causes the ferrules inside not to bite which can at pressure releases tubing making it become a project leaver tightening can crush and damage the ferrule sit can crush the nut and cause leakage.

So, We want to make sure that this nut is tightened to the precise spot every time so what can happen if we install a fitting that's over-tightened or under tight first of all you may have to throw away the fitting a tubing run might have to be replaced which causes a lot of time and expense also more concerning is the potential for safety issues so the media running through our tubing may be at high pressure it may be at high temperature and it might be caustic chemicals which could be harmful so anytime we increase the potential fora leak we're looking at serious consequences.

Now, I want to tell you an amazing new patent which limits the potential of human error which is what we're dealing with today is installing this correctly is the human error factor this is a new patented tube fitting from Tactlok what Tactlok has done is put built-in gap gauges on every fitting because most installers are not using the gap gauge to check a fitting and make sure it's done correctly.

So I’m going to remove these ferrules and give you a demonstration of what a gap gauge fitting does with Tactlok you take the tubing you insert it into the fitting fully and you start tightening the nut you tighten with a wrench until these red rings pop away these red rings are amazing new built-in gap gauge what this does is eliminate the need to carry a gap gauge and most people in the industry are not using a gap gauge to install fittings any way, So they're really not following the manufacturer's instructions now we've eliminated the need for a gap gauge by having a built-in gap gauge on every fitting so the distance is always correct it's not over tightened and it's not under tighten it's tightened at the exact right spot every time for maximum seal and safety this simple patent is rocking the industry.

A Complete Guide to Stainless Steel Bulkhead Fittings

Bulkhead fittings are specially built fittings that allow liquids during a tank to flow freely and drum drainage and other plumbing connections. during a piping scheme, these fittings are often used as delivery outlets. Bulkhead fittings provide an endless flow of water and are often wont to connect flexible pipes using male adapters.
A bulkhead fitting may be a connector that's intended to be placed on a flat surface after passing through a tank wall. The fitting is formed from a bulkhead with a pipe socket or a threaded attachment, a gasket, and a locking nut. Bulkhead fittings are available in a sort of sizes and materials. These fittings usually have left-handed threads that aid keeps the fitting intact and solid when installing the male adapter. chrome steel bulkhead fitting, when combined with unions, makes it easier to get rid of pumps and accessories. Bulkhead fittings also are sold with nuts and gaskets as extras. Typically, gaskets are obtained separately.

 

Tips to buy Bulkhead Fittings

The following considerations should be weighed when purchasing bulkhead fittings:

  • The thread size of the fitting is often determined when ordering bulkhead fittings in bulk.
  • Since bulkhead fittings function delivery outlets in piping systems, the diameter of the bulkhead fitting is critical.
  • When purchasing bulkhead fittings, the size of the fitting is additionally a big factor to recollect.
  • The consistency and strength of the fabric wont to make the fitting also are essential factors to recollect.

How to Install Bulkhead Fittings?

The steps for installing bulkhead fittings are as follows:

  1. Hole Drilling: to put in a bulkhead fitting, first cut or bore a hole at rock bottom of the tank or reservoir to which the pipes are often attached. make certain you weigh and choose the size of the bulkhead’s exterior, so you recognize how big to drill the opening.
  2. Bulkhead Fitting: After drilling the opening, install the bulkhead fitting with the threads inside or outside the tank or reservoir, counting on how you would like the connections to figure.
  3. Gasket and Locknut Fittings: Finally, install the gasket.

Use one gasket on either side of the walls if you've got two. Thread the locknut down by applying pressure to the gasket together with your palm. The locknut would then have a solid-liquid seal with no leaks. But take care to not over-tighten to avoid breaking or distorting the gasket and causing a leak.

The Advantages of Using Bulkhead Fittings

  • The bulkhead fitting would offer a liquid-tight link.
  • They are ideal for plumbing links in hydroponics or aquaponics.
  • They facilitate the availability of water into the tanks or reservoirs.
  • Several Stainless-steel bulkhead fitting is usually utilized in the sink to permit fast water flow.
  • Water leakage isn't a problem with bulkhead fittings.
  • They are often utilized in any mechanism that permits large drums or barrels to be crammed with water.
  • They are often utilized in ponds to link pipes that leave fast drainage. instead of scooping water from the bucket, this makes changing water faster.
  • They are commonly found in predicament pipe systems, especially brass bulkhead fittings.
  • Typically utilized in the transportation of liquid tanks.

With that said, you’ve learned a thing or two about what a bulkhead fitting is. it's therefore essential to follow this guide for a successful stainless-steel bulkhead fitting job.

 

 

 

 

 

Basic comparison between SS 316 and Duplex Stainless Steel

So you're trying to seek out the difference between SS 316 and Duplex Stainless steel? Before having knowledge about those steel, you would like to understand what's stainless steel and why it's different types?

Stainless Steel is that the common name of steel that uses for its corrosion resistance. There are numerous differences in its kind, but the similarity in every stainless steel contains a low amount of chromium. Stainless steel is split into few types, like Ferritic, Austenitic, Martensitic, and Duplex. As we are considering SS 316 and Duplex during this article, both have their specific qualities and this is often the rationale that both are utilized in a good range of applications in several industries.

 

SS 316: It comes under the austenitic sort of stainless steel. it's known for its 2-3% molybdenum content. Molybdenum makes the metal more vigorous or gives resistance to corrosion and to beat ascended temperature.

Duplex Stainless Steel: It's a two-phase microstructure consists of a grain that is ferritic and solid solution stainless steel. because it has the potential of cooling to temperature, half the ferritic grains convert to austenitic grains. When duplex steel commences melting, it solidifies from the liquid state to the ferritic phase.

Difference between SS316 & Duplex Steel

  • Duplex stainless steel features a lower level of nickel and molybdenum that creates it budget-friendly.
  • As compared to SS316, duplex alloys have more resistance to chloride stress corrosion cracking.
  • Duplex steel is more robust than austenitic or SS316 grades. It also provides formability struggling and excellent hardiness.
  • Another difference between SS316 and duplex stainless steel is SS316 contains 18% chromium and eight nickel whereas, Duplex contains 18-28% of chromium and 4.5-8% of nickel or austenitic.

How it relates to Energy Industries?

Stainless steel has many beneficial properties for the facility and energy industries. Among all qualities, the corrosion resistance capacity of chrome steel is extremely much needed in this field in any environment. Another most useful ability of stainless steel within the power energy world is when handling electrical components; it can transfer heat, whether it's a matter of high temperatures and extreme pressure. From traditional coal industries to renewable energy industries, it's getting used. These also are a reason stainless steels are referred to as transformer enclosures, pressure tubes, heat exchangers, and more.
