Still, some types, like the 430, have excellent corrosion resistance and are very heat tolerant.303 Stainless Steel - Penn StainlessAlloy 303 was specially designed to exhibit improved machinability while maintaining good mechanical and corrosion resistant properties Due to the presence of sulfur in the steel composition, Alloy 303 is the most readily machineable austenitic stainless steel; however, the sulfur addition does lower Alloy 303s corrosion resistance to below corrosion sus 303 versus sus 400 series
Machining. 303 was developed as a free machining grade, and has by far the best machinability of all the 300 series austenitic stainless steels, and indeed has better machinability than most of the 400 series martensitic stainless steels with the exception of the free machining grades. It has a typical machinability rating of about 75% - 80% of free machining (S1214) mild steel.(SUS 303, UNS S30300) - NAS 303AM (SUS 303, UNS S30300) is a high free-machining austenitic stainless steel in which machinability is improved by adding sulfur to Type 304. Although sulfur is an alloying element that reduces corrosion resistance, the corrosion resistance of NAS 303AM is close to that of Type 304 in mildly corrosion atmosphere.
