2.How to judge whether cold rolled sheet is high quality？
The main mechanical properties are: yield, tensile, elongation.
Yield strength is the maximum strength that can produce elastic deformation, beyond which the material will not reverse deformation, that is, plastic deformation.
Tensile strength is the yield strength under tension.
Elongation is the maximum length that can be extended without shortening.
In the production process, it is not heated at room temperature, so there is no pitting and oxide sheet defects often occur in hot rolled steel plate, and the surface quality is good and the finish is high. Moreover, the size precision of cold-rolled products is high, and the properties and structure of cold-rolled products can meet some special requirements, such as electromagnetic properties, deep drawing properties, etc.Specifications: minimum thickness 0.2-4mm, width 600-2000mm, length 1200-6000mm.
