ALSO SEE INFORMATION ON 303 ON OUR CASTING PAGE

Description

303 is a free-machining stainless steel specifically designed to exhibit improved machinability. These modifications retain, in so far as possible, the good mechanical properties and corrosion resistance of the basic or patent compositions which they represent. Sulfur is added to produce the free-machine characteristics. Type 303 is a non-magnetic austenitic stainless steel which is not hardenable by heat treatment. It is the free-machining modification of the basic 18% chromium - 8% nickel stainless steel.

Applications

Fasteners, Shafts, Valve Bodies, Valves, Valve Trim, Fittings, Machined parts, and Not recommended for vessels containing liquid or gasses at high pressures
