Introduction
303 stainless steel is an austenitic type free-cutting stainless steel wear-resistant acid steel. To improve the performance of the steel, no more than 0.60% of molybdenum can be added to the steel to resist ablation.
303 stainless steel mechanical properties after annealing and stress relief, tensile resistance 515MPa, yield 205MPa, elongation 40%. Stainless steel 303 has a standard hardness of HRB 90-100, HRC 20-25, Note: HRB100 = HRC22.9.
303 is a free-cutting stainless steel containing sulfur and selenium, respectively, for applications where high cutting and surface finish are required. 303 stainless steel improves cutting performance and high temperature bonding resistance. Ideal for automatic lathes, bolts and nuts
Application
Petroleum, electronics, chemical, pharmaceutical, textile, food, machinery, construction, nuclear power, aerospace, military and other industries!
