SAE 1070/75 SPRING STEEL STRIP

Tempered and
Thermally
Relieved (TR) SAE
1070 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.

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.
