1.Structure of Cold Rolled Steel Description：

With hot rolled steel coils as raw material, after acid pickling to remove oxide skin for cold rolling, the finished product is hard, because of cold work hardening caused by deformation of continuous cold rolling hard roll strength, increase hardness, toughness and plastic index decreased, so the stamping performance will deteriorate, can only be used for simple deformation of the parts.Hard coil can be used as a raw material, hot dip galvanized factory for hot dip galvanizing unit Settings are annealed wire.Hard coil weight generally in June to 13.5 tons, coil diameter is 610 mm. 

2.Main Features of the Cold Rolled Steel：

1, higher precision, cold-rolled strip steel thickness difference of no more than 0.01 ~ 0.03 mm.
2, the size is thinner, cold rolling the thin steel strip rolling 0.001 mm;Hot rolling can reach 0.78 mm the thinnest now.
3, the surface quality is superior, cold rolled steel sheet can even produce the mirror surface;While the surface of hot rolled plate tin oxide, such as pitting defects.
4, can manufacture according to customer requirements to adjust its properties such as tensile strength and process performance such as stamping performance, etc.
Cold rolled and hot rolled is two different types of steel rolling technology, as the name implies, is cold rolled copper under the condition of steel at room temperature, the hardness of the steel.Copper is hot rolled steel in high temperature circumstances.
