Martensitic - Austenitic Stainless Steels

Increasingly used are maraging steels. It has both high mechanical values like martensitic steels and high corrosion resistance like austenitic steels. The symbol 17-4PH comes from 17% chromium and 4% nickel. It is a stainless steel that is at least as resistant to corrosion as 304 steel in most corrosive environments, with its high mechanical properties, and hardens with aging.

Martensitic-austenitic stainless steels; Used in aerospace, medical, hand tools, chemical and food processing equipment and paper manufacturing equipment.
