174ph.jpg

PACIFIC 17-4PH Stainless Steel is a precipitation hardening grade offering high strength with corrosion resistance similar to type 304 in most environments. It is stocked centerless ground and polished in condition H1075. Condition H1075 has been aged (precipitation hardened) at 1075°F for strengthening without sacrificing the machinability of the solution annealed condition. 17-4PH is readily welded and selection of filler metal depends on properties requirements of the welded joint.
