Stainless Steel 321 is one of the popular raw materials that contain a variety of elements in different proportions such as titanium, niobium, carbon, nickel and molybdenum, and several others. This excellent chemical composition offers high tensile strength and corrosion resistance. It also has high-quality creep and also stresses rupture properties. It has many features like high tensile strength, ductility, durability, flexibility, and formability as well. These features make this material suitable for the manufacturing of welded tubes. Stainless Steel 321H Welded Tubes has high strength, resistance to scaling, and phase stability with resistance to subsequent aqueous corrosion. These tubes are best for use in the annealed temperatures without any deformation. Stainless Steel 321H Welded Tubes have adequately worked in both conditions like annealed as well as hardened. It has many outstanding features which mostly used in many application industries.
Our manufacturing team precisely designs each Stainless Steel 321H Welded Tubes by following international standards and specifications.
