Weston Stainless, Midland, UK, is a trusted supplier of high-quality stainless steel fasteners, offering durable and corrosion-resistant solutions for various industrial needs. Stainless Steel 416 Bolts are made from grade 416 martensitic stainless steel, known for its free-machining properties, high strength, and moderate corrosion resistance. These bolts are available in different shapes and sizes, ensuring compatibility with multiple applications. Consisting of chromium (12-14%), iron, carbon (0.15% max), and sulfur (0.15% min), they possess a superior degree of machinability with commendable mechanical behavior suitable for harsh environment use requiring strong machining with stability.
416 Stainless Steel Bolts include 0.15% max carbon, 12-14% chromium, 1% silicon, 0.15% min sulfur, and 1.25% manganese to advance the capability to perform and get better corrosion protection. Their mechanical properties are tensile strength of 550-700 MPa, yield strength of 275 MPa, and up to 35 HRC hardness, providing mechanical durability. Physical properties of 416 stainless steel are 7.75 g/cm³ density and around 1480°C melting point, which provide good thermal strength retention and structural stability under moderate temperatures.
