Stainless steel bars: round bars, hexagonal bars, square steel, flat steel, hexagonal steel , round steel, solid bar.
303Cu stainless steel bar is a stainless steel adding copper and containing sulfur and selenium.
it is mainly used for high cutting and surface finish requirements. 303 Cu stainless steel bars are Ideal for automatic lathes screw and mut.
303Cu austenitic stainless steel bar is acid resistant stainless steel.To improve the performance of steel,
more than 0.60% molybdenum is add in steel , so it can be ablative, easy cutting and corroded.
Adding Cu element and a small amount ofsulfur, phosphorus makes it easier cutted than the 304, and other properties similar to 304 stainless steel bars, but the corrosion resistance is not so good as 304.
