Based on their crystalline structure, stainless steels are generally divided into three groups, namely, martensitic, austenitic and ferritic. A combination of martensitic and ferritic steels forms a fourth group called the precipitation-hardened steels.
The following datasheet provides an overview of grade 422 stainless steel.
Chemical CompositionThe chemical composition of grade 422 stainless steel is outlined in the following table.
| Element | Content (%) |
