303 stainless steel is a non-magnetic, austenitic stainless steel that cannot be hardened by heat treatment, with good weather resistance, toughness and forming properties. Comprised of chromium, nickel, Sulphur, and other alloys, 303 material is designed to exhibit improved machinability while maintaining strong mechanical and anti-corrosion properties. 303 stainless steel plate is typically used for heavily machined parts.
The machinability of 303 steel is due to the presence of Sulphur in the steel composition.The unique element sulfur in 303 steel which contributes to its exceptional machinability. The sulfur inclusion forms manganese sulfide inclusions, aiding in the creation of small, broken chips during machining processes.
