Martensitic & Precipitation Hardening (PH) Stainless Steels

Martensitic Stainless Steels

Martensitic stainless steels are similar to low alloy or carbon steels. They have a structure similar to the ferritics with a 'body-centred tetragonal' (bct) crystal lattice. Due to the addition of carbon, they can be hardened and strengthened by heat treatment, in a similar way to carbon steels. They are classed as a "hard" ferro-magnetic group.

Chemical compositions of AISI (ASTM/ASME) and UNS martensitic and precipitation hardening stainless steel grades

Composition tables for a wide range of standards and special martensitic and precipitation hardened (PH) stainless steels are given.
