17-4PH Stainless Steel Sheet/Plate

17-4PH stainless steel is a precipitation-hardening martensitic stainless steel. Its primary components include chromium (Cr), nickel (Ni), copper (Cu), and niobium (Nb). The chromium content is approximately 15.00%-17.50%, nickel 3.0%-5.0%, copper 3.0%-5.0%, niobium 0.15%-0.45%, and carbon ≤0.07%. It also contains small amounts of silicon, manganese, phosphorus, and sulfur. In most environments, its corrosion resistance is comparable to that of 304 stainless steel and superior to that of 400 series stainless steel. It offers good resistance to air, water, and some dilute acids and salts. However, in highly corrosive environments, its corrosion resistance is inferior to that of 316L stainless steel, which has a higher molybdenum content.
