Stainless Steel 347/347H Welded U Tubes find significant applications in those industries that require resistance to corrosion, heat, and mechanical stresses. Manufactured by leading companies like Metcore Alloys, the tubes assure excellent performance with added durability, especially at high temperatures. Metcore Alloys are reputed manufacturers, suppliers, stockists, and exporters of stainless steel products and offer premium quality 347/347H welded tubes that conform to international standards.
One of the critical features of 347 stainless steel welded tubes is that these are alloyed with columbium, which provides resistance to intergranular corrosion, especially under conditions of extended service at high temperatures. Due to this fact, it has extensive application in chemical processing industries, oil and gas, power generation, and aerospace industries where good resistance against thermal conditions will be the necessary factor.
The 347H variant is a modification of grade 347 with a higher carbon content; it is intended for applications where high strength and greater creep resistance at elevated temperatures are required, compared to the standard 347 alloy.The manufacturing of these tubes, by producers like Metcore Alloys, is done with quality raw materials and advanced welding techniques to ensure structural integrity and consistent performance.
