Based in Chennai, India, Vinit Stainless is a well-known producer and supplier of premium stainless steel 304L pipes that serve a variety of industrial uses. For applications requiring high hygiene, durability, and clean welding without post-weld annealing, SS 304L pipes are perfect because of their exceptional corrosion resistance, weldability, and low carbon content. Vinit Stainless produces precision-engineered 304L pipes using state-of-the-art manufacturing processes and strict quality controls. Our pipes are extensively utilised in sectors where material integrity and long-term performance are crucial, including petrochemicals, food processing, pharmaceuticals, and the maritime industry.
The composition of stainless steel 304L pipes is composed of a maximum of 0.03% carbon and 18–20% chromium and 8–12% nickel. The low carbon reduces carbide precipitation during welding and increases corrosion resistance. These pipes have an elongation of roughly 40%, a yield strength of about 170 MPa, and a tensile strength of about 485 MPa. Even at cryogenic temperatures, exceptional toughness and ductility are guaranteed by the austenitic microstructure. Applications needing excellent corrosion resistance, clean welds, and mechanical dependability in both conventional and mildly aggressive environments are best suited for SS 304L.
