Rithav Pipes and Tubes stands out as a reliable manufacturer and supplier of top-notch Stainless Steel 904L Seamless Pipes, proudly based in Delhi, India. We focus on crafting corrosion-resistant, high-performance seamless pipes from SS 904L—a super austenitic stainless steel grade celebrated for its remarkable resistance to tough environments. Our 904L seamless pipes are produced using cutting-edge techniques to guarantee outstanding dimensional accuracy, strength, and longevity. These pipes find their place in various sectors, including chemical, marine, and pharmaceutical industries, making them perfect for highly corrosive and high-temperature applications. At Rithav Pipes and Tubes, we are dedicated to providing quality, dependability, and competitive pricing throughout India.
Stainless Steel 904L Seamless Pipes are made with significant amounts of chromium (19–23%), nickel (23–28%), along with added molybdenum (4–5%) and copper (1–2%) to ensure excellent corrosion resistance. As a non-stabilized austenitic grade, 904L boasts impressive tensile strength (490–740 MPa), yield strength (220–280 MPa), and good ductility and impact resistance. These seamless pipes are adept at resisting strong reducing acids like sulfuric acid and excel in chloride environments, effectively preventing pitting and stress corrosion cracking. Their seamless design guarantees consistent strength and leak-proof performance, making them ideal for extreme industrial conditions.
