Weston Stainless, Midland, UK is a leading distributor of premium stainless steel fasteners providing long-lasting and resistant solutions to various businesses. One of its popular products, Stainless Steel 409 Nuts, is produced using grade 409 stainless steel, which is a ferritic alloy with superior oxidation and corrosion resistance. The nuts come in hex, square, and dome shapes, which give it versatility in fastening operations. Comprising mostly iron, chromium, and a trace of nickel, these nuts possess excellent mechanical strength and weldability and are suitable for use in the automotive, exhaust systems, and structural industries.
Stainless Steel 409 Nuts consist of around 10.5-11.75% chromium, 0.5% nickel, 0.03% carbon, and minor amounts of manganese, silicon, and nitrogen, providing moderate corrosion resistance and strength. The nuts have a tensile strength of approximately 380-450 MPa, yield strength of 170 MPa, and hardness of up to 89 HRB, thus being tolerant to high-temperature conditions. The density of 409 stainless steel is 7.8 g/cm³ with a melting point of approximately 1530°C, hence its durability. The thermal expansion and conductivity values of the metal render it apt for applications involving exposure to heat.
