Introduction
303 stainless steel is an austenitic free cutting stainless wear-resistant acid steel containing sulfur and selenium respectively. It is used in occasions requiring free cutting and high surface finish.
Mechanical properties of 303 stainless steel after annealing and stress relief, the tensile strength is 515mpa, the yield is 205mpa and the elongation is 40%. The standard hardness of stainless steel 303 is HRB 90-100, HRC 20-25, note: hrb100 = hrc22.9.
303 stainless steel improves cutting performance and high temperature adhesion resistance. Most suitable for automatic lathes, bolts and nuts.
Application fields: petroleum, electronics, chemical industry, medicine, textile, food, machinery, construction, nuclear power, aerospace, military industry and other industries.
