Alloy Stainless Steel 17-4PH Stainless Steel Bar - Guangda special material Co.
Alloy 17-4PH (UNS S17400), Type 630, is a chromium-nickel-copper precipitation-hardening martensitic stainless steel with an addition of niobium. 17-4PH combines high strength and hardness with good corrosion resistance. The alloy is furnished in the solution annealed condition (Condition A).
The material is widely used in the aerospace, marine, paper, energy, offshore and food industries for heavy-duty machine components, bushings, turbine blades, couplings, screws, drive shafts, nuts, measuring devices.
17-4 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.Overaging (aging beyond the peak strength condition) improves resistance to stress corrosion cracking.
