Introduction
Stainless steels are high-alloy 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.
Stainless steels are available in four groups that include
martensitic, austenitic, ferritic and precipitation-hardened steels.
These groups are formed based on the crystalline structure of stainless
steels.
The following datasheet provides an overview of grade 502 stainless
steel.
