Weston Stainless, Midland, UK-based, is a reputable manufacturer and supplier of excellent quality stainless steel products, supplying strong and precise-engineered materials to different sectors. Their 301 Nuts made of Stainless Steel are designed using AISI 301 stainless steel, high-strength austenitic steel resistant to corrosion, which finds great use owing to its brilliant durability, resistance to toughness, and oxidation resistance. In various shapes and forms, such as hex nuts, lock nuts, wing nuts, flange nuts, and dome nuts, they find extensive application in the automotive, aerospace, construction, and marine sectors. The nuts are endowed with greater mechanical strength, wear resistance, and high-temperature capabilities, thus suitable for challenging fastening operations.
Stainless Steel 301 Nuts consist of 16-18% chromium, 6-8% nickel, 2% manganese, 1% silicon, 0.15% carbon, 0.045% phosphorus, and 0.03% sulfur, providing superior strength and corrosion resistance. Their mechanical properties are tensile strength of 760-1035 MPa, yield strength of 205 MPa, elongation of 40%, and hardness up to 41 HRC, offering high durability and flexibility. The physical characteristics have a density of 7.9 g/cm³, melting point of 1400-1455°C, and thermal conductivity of 16.3 W/m·K, which makes them ideal for high-stress and high-temperature fastening.
