301 Full Hard Stainless Steel Coil 2.5-10.0mm Thickness with 16-18% Chromium Content for Industrial Applications
301 stainless steel coil is a metastable austenitic stainless steel that maintains complete austenitic structure under full solid solution conditions. This steel type is exceptionally responsive to cold deformation strengthening, allowing for significant improvements in strength and hardness while retaining adequate plasticity and toughness.
- Excellent atmospheric corrosion resistance for rust-free performance
- Superior cold work hardening capability for enhanced strength
- Good impact energy absorption for safety protection
- Ideal for weight reduction in equipment components
Widely used in high-temperature and electrical industries, medical equipment construction, chemical processing, food industry equipment, agricultural and marine components, food and beverage packaging, kitchen supplies, transportation equipment, fasteners, springs, and screening applications.
