303 Stainless Steel- 300 Series Stainless round bar/ flat bar/ coil
Shanghai unite steel inventory includes 303 grade stainless steel (UNS S30300) in plate, round bar, square bar, hex bar, and rolled flat bar.
Alloy 303 is a non-magnetic, 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; however, the sulfur addition does lower Alloy 303’s corrosion resistance to below that of Alloy 304. Like other austenitic grades, Alloy 303 demonstrates excellent toughness, although the sulfur does reduce this a little as well.
Alloy 303 is frequently used in applications that require parts to be heavily machined. Some examples include:
ASTM/ASME ……………. UNS S30300
EURONORM ……………. FeMi35Cr20Cu4Mo2
DIN ………………………… 2.4660
