產品介紹
烘烤硬化鋼（BH 鋼）是指采用特定化學成分和生產工藝是鋼板中固溶的碳原子，鋼板在交貨狀態下具有低的屈服
強度，沖壓完成后，進行涂漆烘烤時屈服強度增加值的一種新型汽車用鋼。BH 鋼可以提高汽車外板的抗凹陷性，
同時又具有良好的成形性能。廣泛應用于汽車門外板、發動機蓋板等外覆蓋件。
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 relatively
low yield strength at delivery and increased yield strength by certain extents through coating baking draw forming. It
is featured with good formability and stable hardness (BH value), and widely used for manufacturing cover plates of
automobiles such as outside door plates and engine hood plates.
