Features of flattening tolerance of cold-rolled stainless steel coil

Cold rolled stainless steel coils refer to cold-rolled stainless steel coils that are processed into various types of cold-rolled stainless steel coils from steel plates or strips at room temperature through cold processing such as cold drawing, cold bending, and cold drawing.

Advantages: fast forming speed, high output, and no damage to the coating, can be made into a variety of cross-sectional forms to meet the needs of the use conditions; cold rolling can cause a large plastic deformation of the steel, thereby improving the yield of the steel point.

Disadvantages: 1. Although there is no thermal plastic compression during the forming process, there are still residual stresses in the section, which will inevitably affect the overall and local buckling characteristics of the steel; 2. The style of cold-rolled steel is generally an open section, which makes the section free Lower torsional rigidity. It is prone to torsion when it is bent, and it is prone to bending and torsional buckling when it is compressed, and its torsional performance is poor; 3. The wall thickness of cold-rolled formed steel is small, and there is no thickening at the corner of the plate connection, which can withstand local stress The ability to concentrate loads is weak.
