Stainless Steel Round Bar #303

303 Stainless Steel 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 stainless steel 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 stainless steel 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.

ASTM-A-582 & QQ-S-764

 

 

Applications: 303 stainless steel is used in applications that require parts to be heavily machined. These applications include, Nuts and bolts, Screws, Gears, Aircraft fittings, Bushings and Shafts
