Abstract
The present invention is a method for preparing and chroming a blank of steel. This method reduces time and cost to the assembly process. The method includes the following steps: heating steel slabs to a pre-determined temperature, hot rolling the steel slabs to a pre-determined width/thickness; spraying the steel strips with water to remove scaling; pickling the steel strips in acid to remove scaling; rinsing and drying the strips; cold rolling the strips with an electron beam textured tandem mill into strips having a pre-determined thickness; cold rolling the strips with an electron beam temper mill; and stamping the steel strips into a bumper.
