347H Stainless Steel Welded Tubes
Stainless Steel Seamless ‘U’-Tubes
Manufacturers of 347H Stainless Steel Welded Tubes
Our 347H Stainless Steel Welded Tubes are designed for high-temperature applications requiring enhanced strength and excellent corrosion resistance. With a higher carbon content than 347, 347H offers superior creep strength and stability under prolonged exposure to elevated temperatures, making it suitable for demanding industrial environments.
Stabilized with niobium, these tubes exhibit outstanding resistance to intergranular corrosion, even in weld heat-affected zones. They also perform exceptionally well in oxidizing and high-temperature conditions, maintaining durability and structural integrity. The welded construction ensures uniformity, while the smooth surface finish provides additional resistance to scaling and corrosion.
347H Stainless Steel Welded Tubes are ideal for use in industries like chemical processing, power generation, heat exchangers, and petrochemical refineries. Available in a variety of sizes and customizable configurations, they deliver reliable performance, longevity, and resistance to extreme environmental and thermal conditions.
