Product Description
Stainless steel bar 303
303 (UNS S30300) is a non-magnetic, austenitic, free-machining stainless steel that is a modification of the basic 10% chromium -8% nickel
stainless steel specially designed to exhibit improved machinability while maintaining good mechanical and corrosion-resistant properties.

303 stainless steel Corrosion Resistance
Alloy 303 is resistant to mildly corrosive environments. However, the alloy's corrosion resistance is inferior to 304 in most applications.
Its corrosion resistance is superior to 416, another free-machining grade, but is somewhat inferior to other 400 series stainless steels which do not contain higher sulfur levels.
In order to obtain optimal corrosion resistance, it is recommended that Alloy 303 be chemically treated to remove sulfides from the final surfaces.
Heat Resistance of Stainless Steel Alloy 303
Grade 303 stainless steel has good resistance to oxidation when intermittently exposed to temperature up to 760°C temperatures.
It also has good oxidation resistance in continuous service to 870°C. This, however, is not recommended as 303 is sensitive to carbide precipitation with continuous use at 425-860°C.
303 stainless steel bars Welding
Alloy 303 is not recommended for applications requiring welding. If it is necessary to weld the alloy, AWS E312 filler metal may be considered.
303 stainless steel Heat Treatment
Annealing – Heat to a minimum temperature of 1900oF (1038oC) and water quench or rapid cool by other means.
Hardening – Alloy 303 cannot be hardened by thermal treatment, it can only be hardened by cold working
