Stainless Steel 17-4 PH

Grade Summary: Stainless Steel 17-4 PH is a chromium-nickel grade of stainless that may be hardened by a single low temperature precipitation-hardening heat treatment. It has excellent mechanical properties and a high strength level may be obtained by using the hardening  treatment. Scaling and distortion is minimized.  Grade 17-4 PH should not be used in the solution treated condition. The strength and corrosion resistance properties of 17-4 hold up well and it has service temperatures up to 800° F. The fabrication techniques for this steel is similar to those established for the regular stainless grades. 17-4 machines well, has excellent welding characteristics and forges easily.
