Annealed AISI 304/304L Stainless Steel Strip

The AISI 304/304L Annealed Stainless Spring Steel Strip is stainless steel classified as austenitic, cold laminated, widely used in stamped parts for several domestic industry sectors. This steel presents mechanical properties that especially suit applications whose processes require resistance to corrosion, surface finishing, and a high degree of shaping, including those technical parts that require deep-drawing.

The AISI 304/304L Annealed Stainless Spring Steel Strip industry applications are:

  • - Parts stamping requiring stainless steel.
  • - Deep-drawn parts (check hardness).
  • - Clamps, straps, expansion joints, and serpentines.
  • - Surfaces coating

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.
