AISI 420 Tempered Spring Stainless Steel Strip

The AISI 420 tempered spring stainless strip is stainless steel classified as martensitic, magnetic, cold laminated, widely used in the manufacture of springs and devices that require a high degree of hardness, resistance to fatigue, and decrease in production time.

The AISI 420 Tempered Spring Stainless Steel industry applications are:

  • - Parts stamping in general.
  • - Foodstuff line.
  • - Spring Stainless Steel for manufacturing cutting tools and cutlery devices.
  • - Spring Stainless Steel for manufacturing parts used under liquid immersion.
  • - Springs Manufacture.
  • - Saws and meet cutting Discs.
  • - Spring Stainless Steel for the manufacture of parts requiring fatigue resistance.

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.
