17-4 PH Stainless Steel (Precipitation Hardening)

17-4PH alloy is composed of copper, niobium precipitation, hardening, martensitic stainless steel. Features: After heat treatment, the mechanical properties of the product are improved and compressive strength up to 1100-1300 MPa (160-190 ksi) can be achieved. This grade can not be used at temperatures above 300 ° C (572 ° F) or very low temperatures. It has good corrosion resistance to atmospheric and dilute acids or salts, and its corrosion resistance is the same as 304 and 430. 17-4PH is a martensitic precipitation hardened stainless steel .17-4PH performance characteristics is easy to adjust the strength level, you can change the heat treatment process to be adjusted.Martensite transformation and aging treatment to form a precipitation hardening phase is the main means of strengthening, 17-4PH attenuation performance, anti-corrosion fatigue and anti-drop performance.
