AISI 301 stainless steel strip
Good formability, work‑hardenable; high strength in 2H condition.
Description
AISI 301 (EN 1.4310, X10CrNi18-8) is an austenitic stainless steel with reduced nickel and relatively high carbon, designed to work-harden rapidly during cold rolling. This makes it the benchmark grade for spring applications: flat springs, blades, clips, contacts and components that must return to shape after deflection. As precision strip it delivers very high tensile strength in thin gauges with tight tolerances. 3S typically supplies it in the 2H work-hardened condition, in several hardness levels, and on request also annealed 2R/BA, as strip, narrow strips from 3 mm, spools and sheets, in thicknesses from 0.05 to 0.70 mm (annealed) and from 0.05 to 2.50 mm (work-hardened).
Properties
- Very high strength in the 2H work-hardened condition
- Excellent elastic behaviour for springs and blades
- Good corrosion resistance in mild environments
- Available in several hardness levels with tight tolerances
