303 Stainless bar

Grade 303/1.4305 Stainless bar is a non-magnetic, austenitic, free machining stainless steel that is a modification of the basic 18Cr – 8Ni stainless steel. The addition of sulphur (S) and in some cases selenium (Se) produces excellent machining characteristics while maintaining good mechanical and corrosion-resistant properties and high resistance to oxidation. The high sulphur content that dramatically increases cutting speeds also reduces the grades formability making type 303 not readily cold workable. Sharp bending should be avoided. 303/1.4305 Stainless Bar is austenitic at all temperatures and cannot be hardened by heat treatment. Free machining grades are not generally recommended for welding. Typical applications include nuts & bolts, switchgear components, bushings, shafts and gears.
