Product Overview
Introduction to Stainless Steel 422 / UNS S42200 / AISI 422
MOKSH TUBES & FITTINGS LLP is a leading supplier, exporter, importer, and stockist of a complete range of Stainless Steel 422 (UNS S42200) products, including pipes & tubes, pipe fittings, flanges, fasteners, sheets & plates, coils, wires, round bars, flat bars, angles, channels, welding rods, wire mesh, and various custom or hard-to-find SS 422 products.
Stainless Steel 422 is a martensitic stainless steel alloy containing high chromium and moderate carbon, designed for excellent high-temperature strength, oxidation resistance, and good corrosion resistance in mild environments. It offers superior creep and stress rupture performance compared to conventional martensitic grades, making it ideal for turbine and high-heat service components.
SS 422 can be heat treated to achieve high mechanical strength and hardness, and it maintains good toughness even at elevated temperatures. With its combination of wear resistance, hardenability, and moderate corrosion resistance, SS 422 is an excellent choice for demanding industrial applications.
