Harshita Stainless is a reliable manufacturer and supplier of Stainless Steel 904L Pipes in Delhi, India. These high-alloy austenitic pipes are intended for aggressive environments and possess superior resistance against sulfuric, phosphoric, and acetic acids. Both seamless and welded types of pipes are offered, manufactured in accordance with ASTM B677 and ASTM B673 standards. Being highly weldable, tough, and having a longer service life, SS 904L pipes are being extensively used in marine, chemical, and pharmaceutical industries. Harshita Stainless provides accuracy manufacturing, rigorous quality assurance, and prompt delivery nationwide in India for various industrial uses.
Stainless Steel 904L contains 19–23% chromium, 23–28% nickel, 4–5% molybdenum, and 1–2% copper that boosts corrosion resistance, particularly against reducing acids. It has a tensile strength of ~490 MPa, a yield strength of 220 MPa, and elongation of 35%. The reduced carbon content enhances weldability without causing intergranular corrosion. These pipes withstand high-pressure and high-temperature operations with reliability, for which they are best suited.
