Description
303 / 1.4305 Stainless Steel Strip Coil
303 is austenitic free-cutting stainless, wear-resistant and burning-resistant steel. In order to improve the performance of the steel, no more than 0.60% of molybdenum can be added to the steel, which is resistant to ablation, and has good machinability and burning resistance. , Corrosion resistance.
Mechanical properties of 303 stainless steel after annealing and stress relief, the tensile strength is 515MPa, the yield strength is 205MPa, and the elongation is 40%. Standard hardness HRB 90-100, HRC 20-25. (Note: HRB100 = HRC20) For parts that require excellent cutting performance and good surface finish, it is better to use this type of steel.
