Recently, Hebei Iron and Steel Group Co., Ltd. Handan Iron & Steel Co., Ltd. has successfully produced ultra-thin steel stamping steel DC03 on the continuous rolling line of the West District cold rolling mill. After inspection, the product yield strength, tensile strength, strain hardening index, plastic strain ratio, etc., have reached domestic and international levels. The best grade of mechanical properties of steel grades.

The ultra-thin stamping steel DC03 produced this time is mainly used for automotive side panels and parts. The thickness of the product is 0.4mm and the width is 1250mm. It belongs to the limit specification in the design of continuous and unthreaded products. This specification is used for the continuous use of stamping steel. Production is a domestic production difficulty. In order to ensure successful production, the Cold Rolling Plant of Handan Iron and Steel Co., Ltd. cooperates with production and manufacturing departments, technical centers and other units to improve the production process parameters and optimize the production process for the production of ultra-thin steel stamping steel for continuous annealing furnaces to ensure that the products go offline smoothly.
