    Overview

    Our forming steel is available in a choice of widths up to 2050mm and thicknesses up to 3.1mm. This provides opportunities for cutting waste and maximising yield.These products are made using one of two process routes:

    • continuous annealing (CA)
    • batch annealing (BA)

    2. For thicknesses > 0.5mm and ≤ 0.7mm, the value for yield strength is increased

    5. For a thickness of t > 2mm, the r90 value or r-average value is decreased by 0.2.
    6. For design purposes, a lower yield strength ReL of at least 120 N/mm2 can be assumed for DC06 and 140 N/mm2 for DC01/3/4/5.
