Al Shakru Sheets and Plates, a highly regarded manufacturer and supplier based in Dubai, UAE, is proud to provide premium-quality Stainless Steel 420 Sheet and Plates . These products are renowned for their impressive hardness, strength, and corrosion resistance. Produced using advanced methods and superior raw materials, these sheets and plates are ideally suited for applications demanding durability and exceptional performance under pressure. Al Shakru Sheets and Plates prioritizes precision, consistency, and adherence to international standards, ensuring their Stainless Steel 420 products meet a wide range of industrial, engineering, and manufacturing requirements where toughness and wear resistance are essential.
Stainless Steel 420 Sheet and Plates are martensitic stainless steels composed primarily of chromium (12–14%), carbon (0.15–0.40%), manganese, silicon, and small quantities of nickel. This distinctive combination enables the alloy to reach remarkable hardness and reliable corrosion resistance once it has been heat treated. The material offers a tensile strength of roughly 700 MPa, superb polishability, and moderate toughness. It further demonstrates strong resistance to scaling and oxidation up to 650°C, making it well suited for both mechanical and thermal applications.
