Stainless Steel Cold Rolled Sheet

Cold rolling is under the recrystallization of rolling, but generally understood to use room temperature rolling material. Aluminium cold rolled into sheet mill and foil rolling. Thickness above  0.15 ~ called board, 0.15~the following referred to as a foil. Europe and the  United States more than using 3~6 sets of continuous mill as cold rolling  equipment.

The production process

Because it not be heated in the production process, so there is no hot rolled often appear defect such as pitting and tin oxide, good surface quality, high degree of finish.And the size of the cold rolled products of high precision, the  product performance and organization can satisfy some special requirements,such as electromagnetic performance, deep drawing performance, etc.
 Specification: thickness of  0.24mm, width is 600-2000mm, length of steel sheet for 1200-6000mm.
 Brand: Q195A Q235A, Q195AF Q235AF, Q295A (B) - Q345A (B);(SPCC), SPCD, SPCE,  ST12-15;DC01-06
 Performance: mainly adopts low carbon steel grades, which requires good cold  bending and welding performance, as well as certain stamping performance.

Product categories

1. (1)After annealing processed into ordinary cold-rolled;
    (2)galvanized processing galvanized crew with annealing pretreatment devices;
    Basic does not require processing panel

2. Commonly used steel grade CDCM - (SPCC) (SPCD, SPCE, ST12, ST13, ST14,  BLC, BLD, BUSD, BUFD, BSUFD, etc.), but its performance is basically the same.
    3, the common cold rolling;
    4, galvanized;
    5, aluminum zinc plating: continuous melt plating technology is to use the 55%  aluminum and 43.4% zinc and 1.6% silicone coating to the steel sheet surface.

Product features

1. (1)With good durability, compared with galvanized steel longer life;
    (2) has good heat resistance, compared with galvanized steel at high  temperatures and not easy to change color;
    (3) has good heat reflective;
    (4) with the silver gorgeous surface;
    (5) has a similar to galvanized steel processing and spraying performance;
    (6) has a good welding performance.
    Application: apply to demanding in galvanized industry.
    6, electroplating sn (tin) : use of insoluble anode of Florida, Stan  electroplating tin process.
    7, PPGI;
    8, electrical steel, silicon steel sheet

Application field

Cold  rolled steel sheet use is very wide, such as  automotive manufacturing, electrical appliances, vehicles, aerospace, precision  instrument, canned food, etc.

Cold rolled steel sheet is short for ordinary carbon structural steel manufacture, also known as manufacture, commonly known  as the cold sheet, are sometimes mistakenly written as cold sheet. Cold sheet is  made of ordinary carbon structural steel hot-rolled steel belt, after further  made from cold rolled steel sheet thickness is less than 4 mm.Due to rolling at  room temperature, do not produce iron oxide, therefore, the surface of cold sheet is of good quality and size precision is high, coupled with annealing treatment, the mechanical performance and the performance is better than that of the hot rolled sheet steel, in many fields, especially in home appliance  manufacturing areas, has been gradually replace the hot rolled steel sheet with  it.
