301 stainless steel

301 is an austenitic chro-mium-nickel stainless steel that provides high strength and good ductility when cold worked. It is a modification of type 302 in which the chromium and nickel contents are lowered to increase the cold-work-hardening range.

High strength and excellent corrosion resistance make 301 stainless steel useful for a wide variety of applications,typical use include aircraft structural parts, trailer bodies, diaphragms,utensils, architectural and automotive trim,automobile wheel covers,roof drainage products, tablewear,storm door frames and conveyor belts.

301 stainless steel heat treatments

301 is no-hardenable by heat treatment.

Annealing: heat to 1900-20500F(1038-11210C),then water quench.

Stress relief annealing:heat to 500-9000F(260-4820C),then air cool.

301 formability

301 can be readily formed and drawn.due to its high work-hardening rate, intermediate annealing may be necessary for severe drawing and forming operations.
