Cold Rolled Steel Sheet ASTM A36 Low Carbon Steel Sheet Ss400 Q235 Q345 Q355 4340 4130 St37 Carbon Steel Plate Coil Sheet Manufacturer

Short Description:

Cold rolled steel is steel produced by cold rolling. Cold rolling is to further roll No. 1 steel plate to the target
thickness at room temperature. Compared with hot-rolled steel plate, cold-rolled steel plate has more
accurate thickness, smooth and beautiful surface, and also has various superior mechanical properties,
especially processing properties. Because the cold rolled original coil is brittle and hard, it is not suitable for
processing, so generally, the cold-rolled steel plate is required to be delivered to the customer after annealing,
pickling and surface leveling. The maximum thickness of cold rolling is less than 0.1-8.0mm. For example,
the thickness of cold rolled steel plate in most factories is less than 4.5mm.

PRODUCT DESCRIPTION

discrimination

Carbon steel is an alloy with carbon and iron, with carbon content up to 2.1% by weight. The increase in the carbon percentage will raise steel's hardness and strength, but it will be less ductile. Carbon steel has good properties in hardness and strength,and it is less expensive than other steels.
Carbon cold rolled steel coils and strips are produced with a highly adaptable manufacturing process, which are extensively used in automobile, washing machines, refrigerators, electrical appliances and steel office equipment. By varying the percentage in carbon steel, it is possible to produce steel with a variety of different qualities. In general, higher carbon content in steel makes steel harder, brittler and less ductile.
