Weston Stainless, Midland, UK, is a reliable manufacturer of stainless steel products of the highest quality, providing an extensive variety of industrial materials with high precision engineering and excellent durability. Among its superior products, Stainless Steel 17-7 PH Sheet and Plates are renowned for their superior strength, corrosion resistance, and hardness. These plates and sheets, which are produced from Grade 17-7 PH stainless steel, come in different shapes and sizes to suit aerospace, marine, and chemical industries. Produced through a precipitation-hardening process, they exhibit excellent mechanical properties and stability in harsh environments, making them suitable for high-performance applications.
Stainless Steel 17-7 PH Sheets and Plates contain a composition of about 17% Chromium, 7% Nickel, 1.1% Aluminum, with traces of Carbon, Manganese, Silicon, and Phosphorus. Mechanically, they possess a tensile strength of up to 1034 MPa, yield strength of about 724 MPa, with elongation of 6-10%, having excellent fatigue properties. Physically, they possess a density of 7.8 g/cm³, melting point of 1400°C, and good heat conductance. These characteristics render them extremely resistant, corrosion-proof, and suitable for high–strength, toughness, and oxidation-resistant applications in harsh environments.
