Weston Stainless, with its head office in Midland, UK, is a well-known provider of high-grade stainless steel products to industries globally. Among its high-end products, Stainless Steel XM19 Nuts are highly regarded for their excellent corrosion resistance, high strength, and longevity. These nuts are produced using XM19 grade austenitic stainless steel and come in a range of shapes and sizes to suit industrial fastening requirements. With superior pitting, crevice corrosion, and stress corrosion cracking resistance, they provide excellent performance in harsh environments. Their proprietary blend of nitrogen and molybdenum improves their mechanical properties, and they are perfectly suited for demanding marine, aerospace, and chemical applications.
Stainless Steel XM19 Nuts consist of 20-23% chromium, 11-13% nickel, 4-6% manganese, 1.5-3% molybdenum, and nitrogen for improved strength and corrosion resistance. These have a tensile strength of about 895 MPa, a yield strength of 379 MPa, and an elongation of 30%. XM19 has a density of 7.9 g/cm³, offering superior thermal conductivity and oxidation resistance. This grade maintains its mechanical properties even under harsh conditions of temperature, making it particularly appropriate for hostile environments that need high-performance fastening solutions.
