Stainless steels are high-alloy steels. These steels are available in four groups that include martensitic, austenitic, ferritic and precipitation-hardened steels.

Stainless steels contain larger amounts of chromium in comparison with other steels and thus have good corrosion resistance. Most of the stainless steels contain about 10% of chromium.

The following datasheet provides an overview of grade 301 full hard stainless steel.
