Precipitation Hardened  Stainless Steel

15-5PH is a martensitic precipitation hardening stainless steel developed on the basis of 17-4PH. Compared with 17-4PH, this grade reduces the content of chromium and copper and increases the content of nickel. Therefore, it can effectively reduce ferrite after heat treatment. The formation probability and the reduction of aggregation caused by excessive dispersion strengthening phase. In addition to high strength, this steel's outstanding advantages are high transverse toughness and good deformation performance. This grade is mainly used in service environments below 300°C that require high strength, good toughness, and good corrosion resistance, such as high-strength forgings, high-pressure system valve components, aircraft engine parts and fasteners, etc.
