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

Cold rolled sheet GB700-88 hard roll (SPCC) - 1 b and low yield point, stamping plasticity zone shape stability is good
Bright annealing soft board (SPCC) - SD, low yield point, stamping and plasticity zone shape stability is good
Cold rolled deep drawing steel strip SPCD stamping performance better, and slip line should not be created
Cold rolled deep drawing steel belt SPCE fine stamping formability, can reduce the stamping way
