303 Stainless steel hex bars with hexagonal cutting shape,cold drawn with moulds tooling suit for various sizes and length,precision sizes,tolerance customed and good surface of your choice
Comparing 304 hex bars mainly different is S% higher and become easier cutting and soft,easy to drill and turning,also with 303 Cu stainless steel round bars and 303Cu hex stainless steel bars,making ss hex nuts and stainless steel hex head bolts and related products.
Same material like ASTM416,430F easy cutting steel,In china marked Y1Cr18Ni9
With our cold drawn workshop better guarantee the quality inside and soonest delivery to China port for section stainless steel products and cnc parts,our 303 hex bars details as below in table
