Characteristics Of Common Stainless Steel Families

Around the world, stainless steel production has continued to increase as a result of its durability, flexibility, and affordable nature.

Stainless steels, on the other hand, share a lot of characteristics in common, and having an understanding of the various families and grade available will help you find the one that is good for your use.

However, it is essential you know that stainless steel is not made of a single alloy but also with a combination of several other components.

Although stainless steel obtains a great part of their ability to resist corrosion from Chromium, there is numerous combination of other metals sold as stainless steels.

The major step to finding out the best stainless steel when working is to decide the appropriate alloy your product needs and make a purchase from reliable and dependable manufacturers of stainless.

In this article, we will discuss the characteristics of common stainless steel families.

STAINLESS STEEL FAMILIES

Stainless steels can be classified into four families. This signifies a specific property and also gives the impression of the percentage of several metals present in the alloy.

1. Austenitic   Stainless Steels

The austenitic stainless steel is the most common and broadly used family. It is made of Chromium and nickel but some grades usually include manganese and molybdenum.

Although austenitic stainless steel is not magnetic, some grades are magnetic, however, they are an excellent choice for corrosion resistance and creep resistance while being great for welding purposes.

The well-known grades of austenitic stainless steel are 303, 304, 316, 310, and 321.

2. Ferritic Stainless Steel

Its low nickel content has made it the utmost budget-friendly family. With low nickel properties, these alloys chromium, molybdenum, niobium help the ferritic family to increase the strength and creep resistance.

They are mostly nonmagnetic and give decent corrosion resistance and welding ability. They are commonly used in the application.

3. Duplex Stainless Steel

Many alloys created recently are included in this group, they add a mixture of properties from both austenitic stainless steel and ferritic stainless steel.

Its characteristics are dependent on the alloys concerned with good welding ability and formability when compared to other steel families.

Some have improved corrosion ability. Duplex alloys grades use commonly are 318L, LDX 2101, LDX 2304, 2507, and 4501.

4. Martensitic and precipitation hardening stainless steel  

This is the least common stainless steel family but they are common in applications that exact, hardened edge.

The presence of carbon makes tempering and hardening a possibility in this family, thereby making it a leading choice for use in the manufacturing of razors, knives, and, medical equipment.

These stainless steel alloys offer moderate corrosion resistance and also remain magnetic after hardening. The common grades are 410 and 420.

Conclusion

Stainless steel offers a variety of use in various industries. Having an understanding of the exceptional characteristics of various stainless steel alloys is vital to not only warranting durability and safety but improving costs as well.

Still, the austenitic stainless steel is the most common and broadly used because it is made up of chromium and nickel.
