# Method for prevention of premature edge fracture at draw bead

## Abstract

A system for forming a steel material includes a first binder, a second binder, a punch and a carrier blank. The first binder and the second binder are configured to form a draw bead shape in the steel material by compressing the steel material between a draw bead protrusion and a draw bead channel. The punch is configured to form the steel material relative to the first binder and the second binder. The carrier blank is positioned on a surface of the steel material and is configured to cover a portion of the draw bead shape during formation of the draw bead shape in the steel material.
