Essential details

17-4PH can be heat treated to high levels of strength and hardness, and features corrosion resistance and machinability comparable to austenitic 304 stainless. Being martensitic, 17-4 is magnetic.

AISI 630 is capable of being hardened up to approximately 44 Rc when heat treated to condition H900.
