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. For design purposes, the lower limit of Re may be assumed to be 140 N/mm² (14,3 kg/mm²)
  3. The upper limit Re of 280 Mpa is valid only for 8 days from the time of the availability of the product and recomended that the products should be formed within 6 weeks from the time of their availability.
  4. The guarantee period of absence of stretcher strains marks is 3 months for B surface quality products.
