303 is a non-magnetic stainless steel, which is not hardenable by heat treatment. It is the free machining modification of the basic 18% chromium – 8% nickel stainless steel.
303 has good resistance to oxidation at temperatures up to 1700°F. In extreme oxidizing atmospheres, irregular scaling may be encountered, particularly above 1400°F.
Bar also available in PRODEC® enhanced machining grade.
