Ojas Pipes and Tubes, a well-respected manufacturer and supplier based in Kolkata, India, specializes in high-quality Stainless Steel 304H ERW Pipes that are built to handle tough industrial demands. With a strong emphasis on innovation, quality, and precision, Ojas delivers ERW (Electric Resistance Welded) pipes known for their exceptional strength, heat resistance, and durability. The Stainless Steel 304H variant, which has a higher carbon content than standard 304, is particularly adept at withstanding high temperatures. Thanks to their modern facilities and skilled workforce, Ojas guarantees that every product meets international standards, making them a go-to supplier in sectors like power generation, petrochemicals, and thermal processing.
Stainless Steel 304H ERW Pipes are composed of 18–20% chromium, 8–10.5% nickel, and a higher carbon content (0.04–0.10%) compared to standard 304, which boosts their strength at elevated temperatures. These pipes boast a tensile strength of approximately 585 MPa and a yield strength of 240 MPa, with an elongation of around 40%. The ERW manufacturing process ensures a smooth finish and reliable weld integrity. The added carbon enhances creep resistance, making 304H ideal for high-temperature applications, while still offering good corrosion resistance, weldability, and mechanical performance under high thermal and pressure conditions.
