JIS G3101 cold rolled plate is not only more accurate in thickness, but also has a smooth surface compared with hot rolled steel plate. And it also has various superior mechanical properties. Cold rolled steel plate has the characteristics of good surface quality, high dimensional accuracy, and annealing treatment, its mechanical properties and technological properties are better than hot rolled thin steel plate. In many fields, especially in the field of household appliance manufacturing, it has gradually replaced hot rolled steel plate.

1、Chemical composition of the product

2、Advantages of JIS G3101 cold rolled plate

   There is no heating in the production process of JIS G3101 cold rolled plate, so there is no pitting and oxide sheet defects that often occur in hot rolling. It has good surface quality and high finish. 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.

3、The difference between hot rolled plate and cold rolled plate

    Hot rolled plate has low hardness, easy processing and relatively low strength. Cold rolled sheet hardness is high, processing is relatively difficult, but not easy to deformation, and it has a high strength.

    The mechanical property of hot rolled steel plate is worse than that of cold rolled steel plate, but it has better toughness and ductility. Cold rolled steel plate has a certain degree of work hardening, low toughness, but it can achieve a better flexural strength ratio.

4、Applications of  S G3101 cold rolled plate

    It is widely used in the manufacture of various parts, such as bolts, keys, rockers, shafts, rods and various types of steel structures, steel plates and so on.
