Vinit Stainless, one of the best manufacturers and suppliers in Chennai, India, deals exclusively in high-grade Stainless Steel 904L Pipes. These pipes are carefully designed to ensure outstanding resistance to corrosion in extremely aggressive atmospheres, hence very suitable for businesses that handle robust acids and chlorides. Our SS 904L pipes find extensive application due to their higher resistance to pitting, crevice corrosion, and stress corrosion cracking, thus ensuring long-term strength and reliability in demanding fluid handling systems.
904L Stainless Steel is an austenitic high-alloy stainless steel. Its general composition consists of 23-28% Nickel, 19-23% Chromium, 4-5% Molybdenum, and 1-2% Copper with an extremely low carbon content in order to inhibit intergranular corrosion. Mechanically, it has good tensile strength, generally between 490 MPa, and a yield strength of approximately 220 MPa. Its high ductility makes fabrication easy, while its strong mechanical properties provide resilience under operating stress.
