Weston Stainless, Midland, UK, is a top supplier of premium stainless steel products with a focus on precision-engineered fasteners across different industries. Among their products, Stainless Steel 305 Bolts are famous for their outstanding corrosion resistance and enhanced formability. These bolts are made of Grade 305 stainless steel, which contains more nickel, less work hardening, and hence is best suited for cold-forming processes. They come in diverse shapes such as hex bolts, U-bolts, carriage bolts, and eye bolts that meet different industrial requirements. 305 stainless steel material composition supports greater durability that makes these bolts ideal for car, food, and chemical industries.
Stainless Steel 305 Bolts consist of carbon (≤0.12%), chromium (17-19%), nickel (10.5-13%), manganese (≤2%), silicon (≤1%), phosphorus (≤0.045%), and sulfur (≤0.03%), providing great corrosion resistance and less work hardening. They have mechanical properties such as a tensile strength of ≥515 MPa, yield strength of ≥205 MPa, elongation of ≥40%, and hardness of ≤201 Brinell (HB). The physical characteristics have the following properties: density of 8.03 g/cm³, melting point of 1400-1450°C, thermal conductivity of 16.3 W/m·K, and electrical resistivity of 720 nΩ·m, which suit their application in cold-forming processes.
