热轧产品的牌号及用途热轧材料由于其特性，其主要用途集中在机械加工的粗加工行业。SPHC、Q195、SAE1006、08YU含碳量均为6个左右，属于冷成型用钢，适用于制造冷成型加工的零件。一般用于如轧冷，轧产品，加工有一定延伸要求的冲压成型产品，复杂形状的零件加工。以上几种牌号的化学成份及机械性能基本接近，在了解客户使用要求的基础上可以互相替代。 但各钢厂生产的材料在开平加工时，板面平整度会有一定的区别。

Due to the characteristics of hot rolling materials, their main uses are concentrated in the rough processing industry of machining.SPHC, Q195, SAE1006,08YU carbon content is about 6, belong to the cold forming steel, suitable for the manufacture of cold forming processing parts.Generally used for rolling such as cold, rolling products, processing has a certain extension requirements of stamping forming products, complex shape of parts processing.The chemical composition and mechanical properties of the above brands are basically close, and can be replaced by each other on the basis of understanding the customer requirements.But the materials produced by each steel mill in Kaiping processing, the plate flatness will have certain differences.

热轧板是重要的钢材品种，主要反映工业化需求。它具有强度高、韧性好、易于加工成型及良好的可焊接性等优良性能。在汽车用钢中，包括冷轧板和热轧板在内的各种钢板用量占到汽车用钢的50%以上，其中热轧酸洗在汽车行业主要用途如下：汽车底盘系统，包括大梁、副梁等。车轮，包括轮辋、轮辐射等。驾驶室内板。车厢板，主要是各种卡车的车厢底板。其它冲压件，包括防撞保险杠、刹车间闸套等一些汽车内部小零件。

Hot-rolled plate is an important steel variety, mainly reflecting the industrial demand.It has high strength, good toughness, easy to process molding and good weldability and other excellent properties.In automotive steel, the amount of various steel plates including cold rolled plates and hot rolled plates accounts for more than 50% of automotive steel, among which the main uses of hot rolled acid pickling in the automotive industry are as follows: automotive chassis system, including girders, auxiliary beams, etc.Wheels, including rims, wheel radiation, etc.Cab inner plate.Car board, mainly the underplate of various trucks.Other stamping parts, including anti-collision bumper, brake brake and other small parts inside the car.
