Cold-rolled sheet is a product obtained by rolling hot-rolled coils at room temperature below the recrystallization temperature. Mostly used in automobile manufacturing, electrical products, etc. Cold rolling is rolling at the recrystallization temperature, but is generally understood as rolling using a material rolled at room temperature.
Cold rolled high-quality steel sheets: mainly include various high-quality steel cold-rolled sheets, the most commonly used are carbon structural steel sheets, especially cold-rolled steel sheets for deep drawing, which are cold-rolled sheets from low-carbon high-quality steel 08Al.
According to the allowable deviation of the thickness of the steel plate, it is divided into A and B levels of precision, which are widely used in the automobile and tractor industry.
