Short Description:

303 (UNS30300) is a non-magnetic, austenitic stainless steel that is not hardenable by heat treatment. It is the free machining modification of the basic 18% chromium / 8% nickel stainless steel. 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, 303 is the most readily machineable austenitic stainless steel; however, the sulfur addition does lower 303’s corrosion resistance to below that of 304. Like other austenitic grades, 303 demonstrates excellent toughness, although the sulfur does reduce this a little as well.

The alloy is nonmagnetic in the annealed condition , but may become slightly magnetic as a result of cold working. The addition of sulfur negatively impacts the corrosion resistance of 303 making it less resistant than 304 to mildly corrosive environments.
