17-4PH material properties

17-4PH is a chromium-nickel-copper precipitation hardening martensitic stainless steel. This grade of stainless steel has properties such as high strength, hardness and corrosion resistance. After heat treatment, the mechanical properties of the product are more perfect, and the compressive strength can reach as high as 1100-1300MPa (160-190ksi). This grade cannot be used at temperatures higher than 300°C (572°F) or very low. It has good corrosion resistance to atmospheric and dilute acids or salts. Its corrosion resistance is comparable to 304. Magnetic.
