Martensitic precipitation-hardened stainless steel
17-4PH alloys are precipitated, hardened, martensitic stainless steel composed of copper, niobium/columbium.
17-4ph properties: After heat treatment, the mechanical properties of the product are more perfect, can reach up to 1100-1300 Mpa (160-190 ksi) compressive strength.
