Manufacturing form-hardened component, preferably vehicle body component, comprises heating a board of steel in a heating plant to a temperature above the austenitizing temperature of steel, and form curing in a tool

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to a manufacturing process for making form-hardened steel components, especially suited for vehicle body parts. The process involves heating a steel board beyond its austenitizing temperature, thermomechanically reshaping it at high temperatures with significant deformation, and then form-hardening it in a tool. This results in steel components with improved strength and shape accuracy.

Patent Abstract

Manufacturing a form-cured component (1), preferably a vehicle body component, comprises heating a board (2) of steel in a heating plant (3) to a temperature above the austenitizing temperature of steel, and subsequently form curing in a tool (10). The board is thermomechanically reshaped at a temperature of 900-1100[deg] C and with a degree of forming of at least 15%, after heating and immediately before the form curing. An independent claim is also included for the form-cured component, prepared by the above mentioned method.
