Ojas Pipes and Tubes, located in Kolkata, India, stands out as a top manufacturer and supplier of high-quality Stainless Steel 304L ERW Pipes. Renowned for their precision engineering and unwavering quality, Ojas caters to a wide range of industries, including pharmaceuticals, food processing, petrochemicals, and construction. The Stainless Steel 304L ERW (Electric Resistance Welded) Pipes are celebrated for their low carbon content, which boosts weldability and corrosion resistance, particularly after welding. With state-of-the-art production facilities, strict quality control, and a focus on customer satisfaction, Ojas delivers high-performance piping solutions that align with international standards and meet rigorous operational demands.
Stainless Steel 304L ERW Pipes consist of 18–20% chromium, 8–12% nickel, and a low carbon content (maximum 0.03%), which significantly improves resistance to intergranular corrosion post-welding. These pipes boast impressive mechanical properties, featuring a tensile strength of about 485 MPa, a yield strength of around 170 MPa, and an elongation of 40% or more. The ERW process guarantees consistent wall thickness, precise dimensions, and smooth finishes. 304L retains its strength and corrosion resistance in both normal and mildly aggressive environments, making it perfect for applications that involve welding, chemical exposure, or regular cleaning.
