Weston Stainless, a Midland-based UK company, is a well-known supplier and maker of premium stainless steel products, serving different industries with precision-engineered material. The company deals primarily in SS 455 Sheets and Plates, which are recognized for their outstanding strength, corrosion resistance, and toughness. They are produced in Grade 455, which is a martensitic stainless steel with improved mechanical properties. In sheet and plate form, the material contains mostly chromium, nickel, and titanium, making it highly durable and resistant to oxidation. SS 455 Plates and Sheets find extensive application in aerospace, automotive, and industrial sectors where high performance is necessary.
SS 455 Plates and Sheets consist of about 11-13% Chromium, 7-9.5% Nickel, 0.8-1.4% Titanium, traces of Carbon, Manganese, and Molybdenum, and the rest Iron. Mechanically, they have tensile strength of up to 1275 MPa, yield strength of about 865 MPa, and hardness of up to 45 HRC, depending on heat treatment. Their physical characteristics are a density of 7.7 g/cm³, thermal conductivity of 25 W/m·K, and an electrical resistivity of 75 µΩ·cm. They are best suited for applications that demand high strength, wear resistance, and superior corrosion resistance.
