Cold Drawn ASTM A213 GRADE TP 321 Heat Exchanger Tube SMLS , Fully Annealed
Specifications:
A stainless steel tube is a hollow cross section that has no seams. Compared with stainless steel tube products solid steel bar, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, the bicycle frame and steel construction with scaffold. Stainless steel pipe manufacturing circular parts, can improve the utilization rate of materials, simplify the manufacturing process, material saving and working hours, such as rolling bearing ring, Jack and so on, are widely used to manufacture stainless steel tube.
