Non-aging extra deep-drawing quality steels (Ultra low carbon IF steels)

البدائللا يوجد بديل لهذه الورقة.

Flat / Cold Rolled

Cold rolled coils or flat steel products are produced by rolling hot rolled flat steels without a heat treatment operation in a thickness range of 0.20 to 2.00mm. While the product’s physical properties are all homogeneous along the strip, surface flatness, width and thickness values have fulfilled expectations at the top level.

  1. Tensile test values apply to "transverse" test pieces
  2. The value of r90 only apply to products of thickness d ≥ 0.5 mm.
  3. The value of n90 only apply to products of thickness d ≥ 0.5 mm.
  4. For design purposes, the lower limit of Re may be assumed to be 120 N/mm² (12.2 kg/mm²)
  5. There is no guarantee period limit for absence of stretcher strains marks. Guarantee periods of mechanical properties are 6 months.
