TECHNICAL DATA SHEET - 17-4PH
17-4PH, a martensitic type precipitation-hardening stainless steel that provides an excellent combination of high strength and hardness along with excellent corrosion resistance.
17-4PH has good fabricating features, and it can be age hardened by a different temperature control.
17-4PH is widely used in manufacturing the high strength, anti-corrosive forge piece for planes, gas turbine and other machined parts.
