Kalpataru Piping Solutions is a trusted manufacturer, supplier, exporter, and stockist of premium-quality 904L Stainless Steel Pipes. These pipes are made from a non-stabilized, low-carbon, high-alloy austenitic stainless steel. Designed for harsh corrosive environments, Grade 904L Pipes offer excellent resistance to uniform corrosion, especially in dilute sulfuric acid, thanks to their high chromium, nickel, molybdenum, and copper content. The addition of copper further enhances their performance against strong reducing acids like sulfuric acid.
904L Stainless Steel Seamless Pipes are highly resistant to chloride-induced pitting, crevice corrosion, and stress corrosion cracking. They are non-magnetic, offer excellent weldability and formability, and do not require pre- or post-weld heat treatment in most cases. These pipes were originally developed for corrosion resistance in sulfuric acid applications and have since proven effective in various demanding environments.
904L Welded Pipes, however, are a high-purity, low-sulfur grade and may not machine easily. In many applications, alternatives can deliver similar performance at a lower cost, making 904L less commonly used today. Still, in environments where superior corrosion resistance is essential, 904L pipes are an excellent choice. They offer performance that bridges the gap between standard austenitic grades like 316L and higher-alloyed grades like those with 6% molybdenum.
At Kalpataru Piping Solutions, we manufacture ASTM A312 TP904L Seamless Pipes and ASTM A358 904L EFW Pipes under stringent quality standards. Our state-of-the-art facilities and high-grade raw materials ensure the production of reliable and durable products. We offer round, rectangular, square, and hollow 904L stainless steel pipes in various diameters and wall thicknesses to meet diverse application needs.
