Stainless steel is defined today as a steel alloy containing at least 10% chromium, plus other elements – especially nickel. The chromium forms an oxide film on the material which makes it corrosion resistant. Nickel, the second most common element in stainless steel alloys, increases ductility, corrosion resistance, scaling resistance, and high-temperature strength.

303

Alloy 303 is an 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. 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. Alloy 303 is a phosphorus and sulfur added alloy for easier machining. For heavier cuts in automatic machining. Cannot be hardened by heat treatment, but hardenable by cold working to obtain with higher tensile strengths. Non-magnetic. Good for high and low temperatures. Excellent bending and forming properties. Typically in automatic machining operations.
