Impex Tube India, a leading Mumbai-based manufacturer and supplier, provides high-quality stainless steel pipes and tubes for stringent industrial use. Among its higher-end products is Stainless Steel 304H Welded Tubing, which is specifically designed for high-temperature service and pressure systems. Characterized by greater strength and resistance, this tubing is produced by employing the latest technology and in accordance with international quality standards. Impex Tube India is committed to providing reliable and efficient welded tubing solutions for the power, petrochemical, and processing industries, ensuring long-term performance and customer satisfaction globally.
Stainless Steel 304H Welded Tubing is a high-carbon version of 304 stainless steel, with a carbon range of 0.04% to 0.10%, making it more resistant to high-temperature strength and creep. The alloy is 18–20% chromium and 8–11% nickel, giving it excellent corrosion and oxidation resistance. It has a minimum tensile strength of 515 MPa and a minimum yield strength of 205 MPa, with satisfactory elongation and structural stability. The welded fabrication guarantees strength and uniformity, while the increased carbon level makes 304H perfect for high-temperature conditions in industrial use.
