Weston Stainless in Midland, UK, is a top-grade supplier of premium stainless steel items, offering high-strength and corrosion-resistant material for use across industries. Its prominent product among them is the Stainless Steel 418 Bar, which is martensitic stainless steel that excels in terms of heat resistance, toughness, and wear resistance. Grade 418 manufactured Stainless Steel 418 Bar is made available in a variety of shapes such as round, square, hexagonal, and flat form. Manufactured with high nickel and chromium content, it provides better mechanical strength and oxidation resistance and is thus suitable for high-temperature as well as harsh environment applications.
Stainless Steel 418 Bar contains iron, chromium (12.0-14.0%), nickel (1.5-2.5%), carbon (0.15-0.20%), manganese (1.0% max), and molybdenum (0.5-1.0%), which gives better strength and corrosion resistance. It has a tensile strength of around 850 MPa, yield strength of 500 MPa, and elongation of about 15%. Having a density of 7.75 g/cm³ and melting point of around 1460°C, it possesses good thermal conductivity and thermal stability at high temperatures. Its hardness is between 98-102 HRB, which provides excellent wear resistance and durability in harsh environments.
