For high-temperature and high-pressure applications, Vipul Pipes and Tubes, a reputable manufacturer and supplier with headquarters in Chennai, India, provides premium stainless steel 304H seamless tubing. A high-carbon variant of the well-known 304 stainless steel grade, SS 304H was created especially to provide better creep strength and structural integrity at higher temperatures. Because our seamless tubing is made without any welds, it has smooth interior finishes, uniform wall thickness, and exceptional pressure resistance. Perfect for petrochemical, power generation, and thermal processing industries, 304H seamless tubing meets international quality standards and performs reliably even in demanding operating conditions.
Increased carbon content (0.04–0.10%), chromium (18–20%), and nickel (8–11%) are all present in stainless steel 304H seamless tubing. Compared to regular 304 or 304L grades, this increased carbon content improves creep resistance and high-temperature strength. It has a yield strength of about 205 MPa and a tensile strength of roughly 515–750 MPa. Excellent oxidation resistance, good weldability, and mechanical integrity are all displayed by the tubing in temperatures higher than 500°C. Because seamless construction eliminates the possibility of seam failure, it guarantees consistent performance and is appropriate for applications involving high internal pressure and thermal cycling.
