DESCRIPATION: SS 301 is an austenitic Chromium-Nickel stainless steel capable of attaining high strength with moderate cold working. Lower Chrome and Nickel content increase the work hardening rate to give high strength and abrasion resistance. Particularly suitable for components requiring stretch forming, high strength or good spring properties.
APPLICATIONS: Springs, Pressings, Connectors, Chemically etched components. (Constant Force Springs, Spring for Dog leashes, Spring for measuring tape, Oil gauge and Wheel covers for automobile, Dome switch in mobile phone, Electric Parts, Drop flat wire, Aircraft structural parts, Automotive trim and Conveyor belts etc.)
