Stainless steel is the generic term used for the corrosive resistant steel alloy that is found commonly in everyday life. From our infrastructure to our kitchen appliances, stainless steel is used to hold everything together.

What is Stainless Steel? Different Types, How to Buy and Suppliers

All stainless steel is naturally corrosive resistant due to a thin film that forms over its surface, actively protecting itself from corrosion by oxygen.


Austenitic Stainless Steel (304, 316, 317)

Austenitic stainless steel, graded 304, 316 and 317, is the most commonly used stainless steel in the market. Due to its high nickel quantity it is also the most expensive steel to use, yet produces the preferred results as it has the highest corrosion resistance as well as being non-magnetic. Austenitic grade stainless can only be hardened by cold work.

Ferritic Stainless Steel (430, 434)

Ferritic Stainless Steel, grades 430 & 434 are less commonly used than austenitic steel yet still has its place. Like its more common partner, ferritic steel is also hardened solely by cold work. Ferritic steel is magnetic, but cheaper than austenitic steel due to its lower nickel content.

Martensitic Stainless Steel (410, 420)

The least common of the stainless steels found on the market, martensitic steel has the highest hardness out of any type of stainless steel. Grades 410 and 420, martensitic steel is magnetic, and is hardened through a combination of both cold work and heat treatment.

How to Buy
