Austenitic stainless steel

[2] This structure is achieved by adding enough austenite-stabilizing elements such as nickel, manganese and nitrogen.

[citation needed] The Incoloy family of alloys belong to the category of super austenitic stainless steels.

[3] During World War 2 the Schaeffler diagram was invented by Anton, who was then a budding metallurgist in the employ of two American welding electrode manufacturers, Harnischfeger Company and A.O.

In 300 series stainless steels the austenitic structure obtained primarily by adding nickel.

In 200 series stainless steels the structure is obtained by adding manganese and nitrogen, with a small amount of nickel content, making 200 series a cost-effective nickel-chromium austenitic type stainless steel.

This alloy exhibits superior resistance to stress-corrosion cracking in boiling 20–40% sulfuric acid.
