Irfan Pipes and Tubes, Istanbul, Turkey, is a renowned manufacturer and supplier of welded 304H stainless steel tubing, providing high-end solutions customized for structural and high-temperature applications. With utmost emphasis on material integrity, dimensional tolerance, and international quality standards, the company provides welded tubing for extreme applications. Stainless steel 304H is a high-carbon version of the popular 304 grade and is formulated to provide increased strength and heat resistance. Irfan Pipes and Tubes is offering 304H welded tubing to customers from various industries like power generation, petrochemicals, and heat exchangers with assured performance and reliability.
Stainless steel 304H welded tubing has about 18% chromium and 8% nickel, along with slightly higher carbon levels (0.04–0.10%) than type 304, enhancing high temperature strength and creep resistance. It has a tensile strength of about 585 MPa and a yield strength of 240 MPa, and it retains good ductility and toughness even at high temperatures. Welded form gives the structural strength and is appropriate for uses where seamless tubing is not needed. 304H has superior resistance to oxidation and scaling at temperatures up to 800°C, which makes it a good material for heat-exposed structural parts, and still provides good corrosion resistance in a wide range of environments.

Stainless steel 304H welded tubing has general application across high-pressure and high-temperature applications in various different industries. It is used in boilers, heat exchangers, superheaters, and pressure vessels because of its resistance to elevated temperatures and retention of mechanical properties. In refinery processes and power plants, it ensures transport of fluid and gas in regions that are subject to thermal cycling and corrosion. The welded configuration is economical to produce and can be used in systems where seamless tubes are not a necessity. Its weldability and structural integrity at good levels make it a material of choice for process piping and thermal equipment.
