Cold Rolled Automotive Steel B220P2

Cold Rolled Automotive Steel B220P2(BP380) high-strength phosphor steel product sizes:
Nominal thickness: 0.45mm~2.5mm, nominal width: 800mm~1850mm

Cold Rolled Automotive Steel B220P2(BP380) high-strength phosphor steel refers to low carbon or ultra-low carbon steel especially added with certain amount of phosphor, which increases steel strength by its solid solution strengthening function. Adoption of such plates may properly reduce thickness of automotive drawn parts thus lighten automobile dead weight. They can be used for manufacturing outside cover parts such as outside door plates, engine hood plates, top cover plates, and reinforcements and structural members such as cross beams and longitudinal beams.
