17-4PH Forging Square Billet For Mask Machine
17-4PH stainless steel is a precipitated, hardened, martensitic stainless steel composed of copper, niobium/columbium. This grade has high strength, hardness (up to 3000C/5000C) and corrosion resistance. After heat treatment, the mechanical properties of the product are more perfect, can achieve up to 1100-1300 mpa (160-190 ksi) compressive strength. It has good corrosion resistance to atmosphere and dilute acid or salt.
