Weston Stainless, based in Midland, UK, is a prominent supplier and producer of high-grade stainless steel products, offering dependable solutions for numerous industries. The company deals in Stainless Steel 13-8 PH Bars, which are renowned for their superior strength, toughness, and corrosion resistance. These bars are produced in Grade 13-8 PH, a precipitation-hardening stainless steel with superior mechanical properties. Coming in round, square, and hexagonal forms, the composition is mostly chromium, nickel, and molybdenum for maximum strength and performance. They are used extensively in aerospace, marine, and industrial usage that demands high strength and dependability.
Stainless Steel 13-8 PH Bar contains around 12.25-13.75% Chromium, 7.5-8.5% Nickel, 2-2.5% Molybdenum, 0.9-1.35% Aluminum, and minor quantities of Carbon, Manganese, and Silicon, with the balance being Iron. Mechanically, it has tensile strength up to 1380 MPa, yield strength of around 1275 MPa, and hardness up to 45 HRC based on heat treatment. Its physical characteristics are a density of 7.76 g/cm³, thermal conductivity of 18 W/m·K, and an electrical resistivity of 90 µΩ·cm. They are suited best for applications that require high-strength and corrosion-resistance in harsh environments.
