Weston Stainless, Midland, UK, is a well-known manufacturer of high-quality stainless steel fasteners, supplying precision-engineered products for commercial and industrial purposes. Stainless Steel 416 Nuts are produced from grade 416 martensitic stainless steel, which has high machinability, superior wear resistance, and moderate corrosion resistance. These nuts come in hex, square, dome, flange, and coupling forms, serving a wide range of fastening purposes. With a 12-14% chromium, 0.15% carbon, and 0.15-0.35% sulfur composition, Stainless Steel 416 Nuts contain high strength, durability, and resistance to scaling, which suit them for applications in automotive, aerospace, and general engineering fields.
Stainless Steel 416 Nuts have a composition that contains 12-14% chromium, 0.15% carbon, and 0.15-0.35% sulfur to improve their machinability. Other components such as manganese, silicon, phosphorus, and iron add their strength and stability. Mechanically, these nuts have tensile strength of 585 MPa, yield strength of 275 MPa, and hardness of up to 32 HRC, providing structural reliability. They have physical properties of density of 7.7 g/cm³ and melting point of approximately 1480°C, and are thus apt for high-temperature applications. Stainless Steel 416 also has good oxidation resistance up to 760°C.
