Stainless Steel 17-7 PH Sheets and Plates are top-notch, high-strength stainless steel products designed to excel in corrosion resistance, mechanical performance, and durability. With a composition that includes chromium (16–17.5%), nickel (6–7%), and a touch of aluminum and copper, 17-7 PH stainless steel stands out for its impressive resistance to oxidation, stress corrosion, and general atmospheric wear. These sheets and plates are crafted with precision, ensuring uniform thickness, a smooth surface finish, and accurate dimensions, making them perfect for aerospace, chemical, petrochemical, and high-performance engineering applications. The combination of high strength, hardness, and corrosion resistance in Stainless Steel 17-7 PH Sheets and Plates makes them ideal for structural, mechanical, and critical industrial components.
The makeup of Stainless Steel 17-7 PH Sheets and Plates primarily includes iron, chromium (16–17.5%), nickel (6–7%), along with small amounts of aluminum, copper, and niobium/tantalum to facilitate precipitation hardening. While mechanical properties can vary based on heat treatment, they typically boast a tensile strength of 1,100–1,400 MPa, yield strength of 860–1,100 MPa, and good elongation. The precipitation-hardening process enables the material to achieve impressive hardness and strength while still maintaining its corrosion resistance and toughness. These traits make 17-7 PH sheets and plates perfect for critical, high-strength applications that demand reliability under stress and in corrosive environments.
