Description:
Grade 17-4ph stainless steels are martensitic stainless steels that
are precipitation hardened to achieve excellent mechanical
properties. These steel achieve high strength and hardness
following heat treatment. The heat and corrosion resistance of
grade 630 are similar to that of grade 304 steels. This grades is
also commonly referred to as grade 17-4PH.
