SAE 1070/75 SPRING STEEL STRIP

The SAE 1070 spring steel strip is a high-carbon steel, tempered and thermally relieved, used in the manufacture of flat parts, whose process implies a low level of conformation and decrease in the production time, as the final product does not require going through a final the tempering process.
Its major characteristic is the high degree of mechanical resistance, along with good tenacity, allowing for bending of up to 90°.

SAE 1070 TR spring steel applications in the industry are:

  • Steel scraper blades.
  • Steel saw for cutting foams, mattresses, wood, and paper.
  • 1070 Spring Steel for manufacturing springs in general and rings.
  • Spring Steel for washers of all kinds.
  • Compressor valves.
  • Steel trowels and construction accessories.
  • Steel framing and straight edges.
  • Steel straps and strips.
  • Spring steel for cutlery.
  • Spring steel for cutting tools.
  • Steel shims for tools.
