Product Details


303 Stainless steel pipe is an austenitic shape containing sulfur and selenium, easily cut and wear-resistant acid steel, used to require easy cutting and surface finish high standards: GB/T 1220 Special Additions: 0.60 ﹪ Molybdenum

 

303 Stainless Steel Pipe

Standard: GB/t 1220

303 stainless steel pipe is an austenitic shape easy to cut wear-resistant acid steel, in order to improve the performance of the steel, can be added in the steel not more than 0.60 ﹪ molybdenum, can be resistant to ablation.

303 stainless steel mechanical properties after annealing to stress, tensile 515MPa, yield 205MPa, elongation rate of 40%. Stainless Steel 303 Standard hardness HRB 90-100, HRC 20-25, note: HRB100 = HRC22.9. 303 is easy to cut stainless steel which contains sulfur and selenium respectively, and is used for occasions where easy cutting and high surface finish are required.

303 stainless steel improves cutting performance and high temperature resistance bonding properties.
