Product Description
Double reduced cold-rolled tinplate coil is given a partial cold reduction to reach an intermediate gauge, then annealed and given another cold reduction to the final gauge prior to coating with tin. The resulting product is stiffer, harder, and stronger than single reduced cold-rolled tinplate coil. T inplate coil is a steel product with a stampable thin steel coil as the base, tin plating on the surface, and multiple protective films . It is characterized by corrosion resistance, non-toxic, odorless, glossy surface, light weight, high strength. In the meanwhile, it is easy to weld and process, aside from a strong adaptability to ambient temperature. Double cold-reduced tinplate coil is usually supplied with a stone surface finish and a flow-brightened tin coating. When ordering double cold-reduced tinplate coil, the purpose of manufacture for which the material is intended should be stated. Double r educed cold-rolled tinplate coil is relatively less ductile than single reduced cold-rolled tinplate coil and has very distinct directional properties, so for some uses, for example for built-up can bodies, the direction of rolling should be stated.
