Stainless Steel 347/347H Welded Tubes Stainless steel 347 and 347H welded tubes represent a particular class of product serving with superior corrosion resistance and strength at high temperatures, applicable in many industrial activities. Indeed, at Reliable Steel Distributors, we pride ourselves on being leading manufacturers, suppliers, stockists, and exporters of excellent-quality welded tubes. Our dedication to quality and customer satisfaction will ensure that you get high-quality products under one roof.

Stainless Steel 347 is an austenitic stainless steel that is stabilized with niobium to prevent carbide precipitation during welding and high-temperature exposure. This gives excellent resistance to intergranular corrosion. The 347H with higher carbon content has increased strength at elevated temperatures. Both grades exhibit exemplary tensile strength and resist a wide range of corrosive environments, such as in applications in chemical processing, petrochemical industries, and power generation.
