AISI 301 Hardened Spring Steel Strip

The AISI 301 Hardened & Stainless Spring Steel Strip is stainless steel classified as austenitic, cold laminated, for manufacturing springs and devices requiring increased hardness, corrosion resistance, and reduced production time.

AISI 301 Hardened & Stainless Spring Steel Strip applications in the industry are:

  • - Parts stamping in general.
  • - Surface coating.
  • - Spring Stainless Steel for manufacturing cutting tools and cutlery devices.
  • - Foodstuff line.
  • - Springs Manufacturing.
  • - Chemical Industry.
  • - Parts requiring surface finishing.
  • - Spring Stainless Steel for manufacturing of parts used under liquid immersion

According to our slitter's technical specifications, our stainless steel strips may be supplied as coils, rolls, or steel strips cut to the width requested by the Customer.
