303 Stainless Steel Round Bar
303 SS is an “18-8″ chromium-nickel stainless steel modified by the addition of selenium or sulphur, as well as phosphorus, to improve machinability and non-seizing properties.
It is the most readily machinable of all the chromium-nickel stainless grades and has a good corrosion resistance, although less than other chromium-nickel grades, such as 304 of 316.
It is non-magnetic in the annealed condition and not hardenable by heat treatment. Tensile strength and hardness can be increased by cold working.
Slight magnetism can be detected by cold working. 303 has excellent scale resistance at temperatures up to 1000 F in continuous service.
It is manufactured by the electric furnace process and meets the exacting requirements of the aircraft industry.
303 is used almost exclusively for parts requiring machining, grinding, or polishing where good corrosion resistance is also required.
Its non-seizing and non-galling properties make it ideal for moving parts. Being austenitic steel, it is useful where low magnetic permeability is desired.
