AISI 414
Stainless steels are high-alloy steels that possess good corrosion resistance in comparison with other steels because they contain more chromium. Based on their crystalline structure, stainless steels are divided into three groups, namely, martensitic, austenitic and ferritic. A combination of martensitic and ferritic steels forms a fourth group known as precipitation-hardened steels.
