Alloy 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. 303 Stainless Steel has the compositional properties that make it the ideal candidate. 303 Stainless is especially optimum for extensive machining practices because of the increased level of sulfur present in its composition. 

Applications of 303 Stainless Steel:Alloy 303 is frequently used in applications that require parts to be heavily machined. Some examples include:Nuts and bolts,Aircraft fittings,Gears,Screws,Shafts,Electrical switchgear components,Bushings
