303Cu 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 303Cu 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.
