Cold rolled bake-hardening high yield strength steel for cold forming

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. There may be deviations for the chemical composition, provided that mechanical property limits are guaranteed.
  3. Guarantee period is 6 months and begin on the date on which products are made available.
