1.Good resistance in applications involving external exposure to mildly corrosive conditions at ambient temperatures.Resists outdoor, industrial, marine, and mild chemical environments.susceptible to carbide precipitation during welding, which restricts its use in some applications.Similar to resistance of Stainless Steel grade 304.

2.Can be exposed continuously without appreciable scaling to a max of 1600°F(871°C).Maximum exposure temperature is about 1450°F (788°C), for intermittent exposure.Has an oxidation weight gain of 10mg/cm 2 in 1,000 hours, in temperatures over 1600°F (871°C).

3.Solution Treatment (Annealing) – Heat to 1010-1120°C and cool rapidly.Use low side of range for intermediate annealing.This grade cannot be hardened by thermal treatment.

4.Hardens at high rate, creating a very high strength from cold rolling and from roll forming.More difficult to work than other austenitic stainless steels, due to its high work hardening rate.Strain-hardened austenitite steel undergoes partial transformation into martensitite steel during this process.Severe cold deformation can still occur, due to residual ductility.Grade 301 becomes strongly magnetic when cold rolled.

5.Must be annealed for maximum corrosion resistance.More difficult to work than other austenitic stainless steels, due to its high work hardening rate..Must be annealed for maximum corrosion resistance.Welding and post weld annealing will both remove high strength induced by prior cold rolling.Spot welding is commonly used to assemble cold rolled 301 components.Material will lose temper in the heat affected weld zone.
