303Cu free cutting stainless steel rod propeties

303Cu stainless steel bar: It is easier to cut than 304 by adding Cu element and a small amount of sulfur and phosphorus. Other properties are similar to those of 304, and the corrosion resistance is not good.

Applications: petroleum, electronics, chemical, pharmaceutical, textile, food, machinery, construction, nuclear power, aerospace, military and other industries!

303Cu is a free-cutting stainless steel with copper added and containing sulfur and selenium, respectively, for applications where high cutting and surface finish are required. 303Cu stainless steel improves cutting performance and high temperature bonding resistance. Most suitable for automatic lathes. Bolts and nuts.

303Cu stainless steel is austenitic type free-cutting stainless steel wear-resistant acid steel. In order to improve the performance of the steel, no more than 0.60% molybdenum can be added to the steel, which can resist ablation, good machinability and burning resistance. Corrosion resistance. 303Cu stainless steel mechanical properties after annealing and stress relief, tensile resistance 515MPa, yield 205MPa, elongation 40%. Stainless steel 303 has a standard hardness of HR
