Cold Rolled Automotive Steel B180H1

Bake hardening steel (BH steel) refers to steel added with some solid solution carbon atoms by adoption of special chemical compositions and production process. It is a new type of high-efficient automotive steel plates with relative low yield strength at delivery and increased yield strength by certain extents through coating baking after their draw forming.
