Material
17-4 PH Stainless Steel
17-4 PH Stainless Steel is a martensitic precipitation-hardening steel with very high strength and hardness after heat treatment and corrosion resistance similar to 304, though it is magnetic and less corrosion resistant than 316.
Manufacturing processes
About
17-4 PH Stainless Steel is a martensitic precipitation-hardening steel.
After solution annealing and aging (H900) it reaches roughly 1,340 MPa tensile strength and about 42 HRC, while as-built parts are weaker (about 900–1,050 MPa). Corrosion resistance is comparable to 304 but below 316 in chlorides, and the strongest condition is more prone to stress corrosion cracking. It is magnetic and suited to service up to about 300 °C.
17-4 PH Stainless Steel is commonly used for pump components, surgical tools, and aerospace and chemical-processing parts.
