JIS SUS 303 Stainless steel ,SUS 303 Stainless steel Hot Working

JIS SUS 303 Stainless steel is the most readily machineable of all the austenitic grades of stainless steel. The corrosion resistance of type 303 is lower than that for 304.

SUS 303 Stainless steel is used in applications that require parts to be heavily machined. These applications include:
Nuts and bolts
Screws
Gears
Aircraft fittings
Bushings
Shafts

SUS 303 Stainless steel Cold Working
SUS 303 Stainless steel is not readily cold workable. Some cold working is possible but sharp bending should not be attempted.

SUS 303 Stainless steel Hot Working
Fabrication methods, like forging, that involve hot working like should occur after uniform heating to 1149-1260°C. The fabricated components should then be rapidly cooled to ensure maximum corrosion resistance.

SUS 303 Stainless steel Heat Treatment
SUS 303 Stainless steel cannot be hardened by heat treatment. Solution treatment or annealing can be done by rapid cooling after heating to 1010-1120°C.
