1.4408 (GX5CrNiMo19-11-2) is a European standard cast austenitic stainless steel, recognized as the cast equivalent of wrought 316L stainless steel. With its molybdenum-enhanced chemistry, this material delivers excellent resistance to chlorides, acids, and high-moisture environments, making it ideal for valve bodies, pump casings, chemical reactors, and marine components.
Product Specifications & Physical Data1.4408 is produced to EN 10213 (pressure purposes) and EN 10283 (corrosion-resistant steel castings) standards. Its primary equivalent is ASTM A351 CF8M (UNS J92900), with additional equivalents including JIS SCS14A and ISO G-X5CrNiMo19-11-2 . The alloy is supplied in the solution-annealed (quenched) condition to optimize corrosion resistance and eliminate carbide precipitation . Available Forms: Castings, valve bodies, pump casings, flanges, fittings, impellers, and custom cast components Specifications: EN 10213, EN 10283, ASTM A351 CF8M, UNS J92900, JIS SCS14A
