Weston Stainless, Midland, UK, is a reputable source of quality stainless steel fasteners, offering tough and precision-fabricated products for industrial use. Stainless Steel 420 Nuts are constructed from grade 420 martensitic stainless steel, characterized by high strength, good hardness, and enhanced wear resistance. These nuts are manufactured in numerous shapes, ranging from hex, square, dome, flange, and coupling forms, suitable for various fastening needs. With a composition consisting of iron, chromium, and carbon, Stainless Steel 420 Nuts possess superior mechanical properties, average corrosion resistance, and superior performance in high-stress conditions, which makes them suitable for use in the automotive, aerospace, and heavy machinery industries.
Stainless Steel 420 Nuts consist of 12-14% chromium, 0.15-0.40% carbon, and traces of manganese, silicon, phosphorus, and sulfur, which make them strong and resistant to wear. Their mechanical properties are tensile strength of 700-850 MPa, yield strength of 500 MPa, and hardness of 45–50 HRC, rendering them extremely tough under heavy loads. Their physical properties are density of 7.7 g/cm³ and melting point of around 1460°C, providing stability at high temperatures. They also show good resistance to oxidation up to 650°C, rendering them suitable for use in high-temperature conditions.
