Free Machining AISI 303Se Cold Drawn Stainless Steel Round Bar Ground Finish
Selenium-bearing, free machining 18-8 chromium-nickel steel. Machinability similar to Type 303
but with improved formability. Should also be considered for applications which involve cold-forming operations.
Alloy 303Se alloy is a free-machining stainless steel specifically designed to exhibit improved
machinability. It is a non-magnetic austenitic stainless steel which is not hardenable by heat treatment. Selenium replaces sulfur to produce the free-machining characteristics and has somewhat improved formability over 303. The good mechanical and corrosion-resistant properties of the lower-sulfur grade
are retained to the extent possible.
303Se should be considered for use in applications such as shafts, valve bodies, valves, valve trim,
and fittings. This steel possesses non-galling properties that make disassembly of parts easy and
help to avoid scratching or galling in moving parts.
