Weston Stainless, with headquarters in Midland, UK, is a prominent supplier of premium stainless steel products, providing optimum solutions to different industries. Of its specialized products, Stainless Steel XM19 Bolts are most notable because of their exceptional strength, corrosion resistance, and durability. These bolts, with various shapes and sizes, are produced from XM19, which is nitrogen-strengthened austenitic stainless steel. Renowned for their superior mechanical properties and resistance to chloride stress corrosion cracking, they are best suited for challenging applications in marine, aerospace, and chemical industries, where reliability and high performance are essential.
Stainless Steel XM19 Bolts consist of 20-23% chromium, 11-13% nickel, 4-6% manganese, 1.5-3% molybdenum, and nitrogen, which offer improved strength and corrosion resistance. They have a tensile strength of about 895 MPa, yield strength of about 379 MPa, and 30% elongation. Having a density of 7.9 g/cm³, they have high oxidation resistance and thermal stability. In contrast to standard stainless steels, XM19 bolts are resistant to degradation of their mechanical properties in hostile environments and thus suitable for use in high-pressure and high-temperature environments.
