Stainless steel
Stainless steel have traditionally been divided into types depending on their microstructure at room temperature, which gives a rough indication of their composition and properties.
Stainless steel can be divided into four main types: ferritic, martensitic and precipitation hardening, duplex, and austenitic – the best steel for you depends on the application.
Ferritic stainless steel
Martensitic and precipitation hardening stainless steel
Duplex stainless steel
Austenitic stainless steel
