With a typical composition of low carbon content, nickel (3.5–5.5%), copper (2.5–4.5%), and chromium (14–15.5%), stainless steel 15-5 PH Circle is a martensitic precipitation-hardening stainless steel. It has a tensile strength of roughly 1310 MPa, a high yield strength of up to 1170 MPa, and exceptional toughness and hardness, particularly after heat treatment. The material is appropriate for precision applications because it has outstanding mechanical qualities in both longitudinal and transverse directions and good corrosion resistance. Better transverse toughness and dependability are provided by its enhanced formability and weldability over 17-4 PH.
