黑钢板是一种很薄的,且具有很高抗拉强度和延伸率的无镀层冷轧钢板。美国正在研制用它来代替一些汽车的铝,塑料件。这种钢板厚度一般不超过0.0142英寸(0.36毫米),延伸率达到了30％,它的高强度一般在成形加工中(硬化)形成。美国钢铁企业用黑钢板制造空气滤清器壳等。黑钢板空气滤清器重2.1磅,比传统的钢制的3.8磅空气滤清器轻1.7磅,约与铝制品件相同,然而其成本仅及铝制品的一半;
Black steel is a thin, uncoated cold rolled steel sheet with high tensile strength and elongation. The United States is developing it to replace some cars aluminum, plastic parts. The thickness of the sheet is typically no more than 0.0142 inches (0.36 mm) and the elongation is up to 30%. Its high strength is typically formed (hardened) during the forming process. US steel companies use black steel to manufacture air filter housings. The black steel air filter weighed 2.1 pounds, about 1.7 pounds lighter than a traditional steel 3.8-lb air cleaner, about the same size as aluminum, but at a cost of just half that of aluminum.
