Weston Stainless is a well-known Midland, UK-based supplier of high-quality stainless steel products serving various industries. Of its top–range products, Stainless Steel XM19 Bars are notable for being highly strong, resistant to corrosion, and long-lasting. The bars, offered in round, square, hexagonal, and flat forms, are made from XM19, a nitrogen-strengthened austenitic stainless steel, which enjoys superior mechanical properties. With excellent stress corrosion cracking resistance and better performance in harsh conditions, these bars are extensively employed in strength, toughness, and longevity-requiring applications such as marine, aerospace, and chemical industries.
Stainless Steel XM19 Bars have 20-23% chromium, 11-13% nickel, 4-6% manganese, 1.5-3% molybdenum, and nitrogen, which helps improve their strength and corrosion resistance. They have a tensile strength of approximately 895 MPa, a yield strength of about 379 MPa, and elongation of 30%. With a density of 7.9 g/cm³, they possess excellent oxidation resistance and thermal stability. XM19 is unlike regular stainless steels, as it maintains its mechanical properties under extreme conditions, and hence is well suited for challenging industrial applications demanding high-strength material.
