17-4PH 630 1.4542 S17400
a precipitation hardening stainless steel which is capable of high strength and hardness levels
after a relatively simple heat treatment prodedure.
This grade is martensitic and magnetic in both the solution treated and precipitation hardened conditions.
It has high resistance to crack propagation, good transverse properities, and corrosion resistance is
normally superior to the regular martensitic chromium type of stainless steels.
Because of the single low temperature 900 to 1150oF precipitation hardening
heat treatment of this grade, scaling and distortio are virually eliminated.
This enables material to be finish machined to close tolerances prior to heat treatment.
