Weston Stainless, having a presence in Midland, UK, is a well-known supplier and producer of excellent stainless steel products, serving many industries with precision-made material. The company specializes in Stainless Steel 15-5 PH Bars, prized for their excellent strength, toughness, and corrosion resistance. These bars are produced in Grade 15-5 PH, a precipitation-hardening stainless steel with enhanced mechanical properties. Comes in round, square, and hexagonal sizes, the material is mostly chromium, nickel, and copper, thus very durable and highly performing. The bars find extensive use in aerospace, marine, and industrial applications involving high strength and reliability.
Stainless Steel 15-5 PH Bar consists of about 14-15.5% Chromium, 3.5-5.5% Nickel, 2.5-4.5% Copper, and traces of Manganese, Silicon, and Carbon, with the rest being Iron. Mechanically, it provides tensile strength of up to 1310 MPa, yield strength of about 1180 MPa, and hardness of up to 45 HRC, varying with heat treatment. Its physical characteristics are 7.8 g/cm³ density, 18 W/m·K thermal conductivity, and 90 µΩ·cm electrical resistivity. These characteristics allow it to be used in highly strength– and corrosion-resistant applications in aerospace, marine, and industrial environments.
