If you are interested to know about Austenitic stainless steel and where to purchase high-quality austenitic stainless steel in India, this comprehensive article will delve into the composition, features, grades, and various applications of austenitic stainless steel, shedding light on its immense potential in diverse industrial applications. We will also let you know about the best place to find and purchase austenitic stainless steel in India from. 

So, without further ado, let us now get to know all about this magic alloy!

What is Austenitic Stainless Steel?

What is Austenitic Stainless Steel?

Stainless steel is classed according to crystalline structure and there are five classes of stainless steel, namely:

  1. Austenitic
  2. Ferritic
  3. Martensitic
  4. Duplex, and 
  5. Precipitation-hardening. 

Among all the above, austenitic is the most common.  Austenitic stainless owes its name to the austenite crystal structure it possesses. When stainless steel is alloyed with nickel, nitrogen, and/or manganese, it gains an austenitic stainless steel structure. This kind of steel has a crystal structure that remains the same across temperature ranges, making it impossible to harden by heat treatment. Austenitic steel grades are also non-magnetic.

Composition of Austenitic Stainless Steel

Austenitic stainless steel composition primarily comprises iron, 16 % to 26 % chromium, and up to 35% nickel, along with small amounts of other elements like manganese, carbon, and nitrogen. The high chromium content (typically above 18%) forms a protective oxide layer on the steel’s surface, shielding it from corrosion. Nickel plays a crucial role in augmenting the steel’s ductility and stability, even at low temperatures. And for information, Austenitic stainless steel density is 7850 kg/m3.

Features of Austenitic Stainless Steel

Austenitic stainless steel boasts impressive features that set it apart from other steel alloys, making it a crucial component used in a wide variety of industries. Some of the major austenitic stainless steel properties are as follows—

  1. High malleability
  2. Superb resistance to corrosion
  3. Extreme heat resistance
  4. Easy cleaning and maintenance
  5. Hygienic, and lastly, 
  6. Attractive

Grades of Austenitic Stainless Steel

There are several austenitic stainless steel grades, each with specific properties and applications. Some of the most commonly used grades of austenitic stainless steel include the following:

  1. 304 Stainless Steel: This grade is the most widely used among all varieties of austenitic stainless steel and also the most common variety of stainless steel in general. It is well-known for its versatility, strength, excellent corrosion resistance, and ease of fabrication.
  2. 316 Stainless Steel: With higher nickel and molybdenum content, 316 stainless steel offers higher heat and corrosion resistance, particularly in chloride environments.
  3.  321 Stainless Steel: This grade of austenitic stainless steel contains titanium, thereby providing resistance against carbide precipitation during welding.
  4. 310 Stainless Steel: Recognized for its strength, high temperature, and oxidation resistance, 310 austenitic stainless steel finds application in heat treatment furnaces, kilns, and combustion chambers.
