Introduction
Stainless steels are high-alloy steels that have excellent corrosion
resistance in comparison with other steels as they contain more
chromium.
Based on their crystalline structure, stainless steels are divided
into three groups, namely, martensitic, austenitic and ferritic steels.
A combination of martensitic and ferritic steels forms a fourth group
known as precipitation-hardened steels.
The following datasheet provides an overview of grade 501 stainless
steel.
