Description
303 303Cu 303F stainless steel bar rod
Profile
303 is a free-cutting stainless steel containing sulfur and selenium, respectively, for applications where easy cutting and high gloss are required. 303 stainless steel has high cutting performance and high temperature bonding resistance, and is most suitable for automatic lathes, bolts and nuts. It is an easy turning material. In addition, 303F, 304F, 316F stainless steel rods also belong to the easy cutting series of bars
