When it comes to chassis components, many have design properties that are in the range where hot rolled steel may be more suitable than cold rolled steel. One of the biggest reasons for this is thickness. Cold rolled steels are generally only available with thicknesses from 0.5 mm to 2.1 mm, whereas hot rolled steel products go beyond, from 2.0 up to 6.0 mm.
In addition to a wide thickness range, Docol® hot rolled AHSS makes it possible to drastically increase the tensile strength in a component, while reducing the amount of material needed to produce it. This can result in a significant reduction in weight, while achieving the same performance and a lower cost, thanks to less material needed overall.
