Stainless Steel 904L Sheet & Plate Manufacturer, Supplier & Exporter in India
Stainless Steel 904L Sheets & Plates supplied by Astromet Steel & Engineering are premium super austenitic stainless steels alloyed with high levels of nickel, chromium, molybdenum, and copper. This advanced chemical composition provides outstanding resistance to strong reducing acids such as sulfuric, phosphoric, and acetic acids, making SS 904L ideal for highly corrosive environments.
SS 904L Sheets & Plates offers excellent resistance to pitting corrosion, crevice corrosion, and stress corrosion cracking, even in chloride-rich and elevated temperature conditions. Its fully austenitic and non-magnetic structure ensures consistent corrosion resistance, high structural stability, and long-term reliability in critical industrial applications.
Stainless Steel 904L Sheets & Plates maintain superior toughness, ductility, and formability over a wide temperature range. SS 904L also demonstrates excellent weldability without the risk of carbide precipitation, allowing easy fabrication while retaining mechanical strength and corrosion resistance after welding.
Manufactured strictly in accordance with ASTM A240 standards, Stainless Steel 904L Sheets & Plates from Astromet Steel & Engineering undergo rigorous quality inspections to ensure chemical consistency, dimensional accuracy, and long service life. Their exceptional durability makes them the preferred choice where conventional stainless steels fail.
