what is a Cold rolled steel plate
Cold rolled steel plate is processed by room temperature rolling, annealing and leveling process, which is a precision flat steel with a smooth and non-scale-free surface, high dimensional accuracy (thickness tolerance ±0.1mm), excellent strength and good formability. Compared with hot-rolled plate, after cold work hardening, it can greatly improve the hardness and mechanical properties, and can meet the needs of precision machining such as stamping, bending and deep drawing, and has been widely used in high-end fields such as automobile body parts, precision mechanical parts, elevator building materials and industrial equipment shells. Provide surface treatment solutions such as oiling and phosphating to effectively reduce subsequent processing processes.

Product Benefits
It has good heat resistance and is less likely to change color at high temperatures than galvanized steel sheets;
It has good heat reflectivity;
It has a gorgeous silver-white surface;
It has similar processing and spraying properties to galvanized steel sheets;
It has good welding properties.
Application
Automobile manufacturing, electrical products, locomotives and rolling stock, aviation, precision instruments, canned food
Production Process
Since no heating is performed during the production process, there are no defects such as pitting and iron oxide scale that are common in hot rolling, and the surface quality is good and the finish is high. In addition, the dimensional accuracy of cold-rolled products is high, and the performance and organization of the products can meet some special use requirements, such as electromagnetic performance, deep drawing performance, etc.
Raw material preparation → pickling and rust removal → endless rolling or conventional rolling → annealing and leveling
FAQ
How to tell if steel is cold rolled?
You can tell cold-rolled steel by its smooth, shiny, scale-free surface, precise edges with sharp corners, and thinner, more dimensionally precise profiles. Cold-rolled steels are generally harder and have an oil-based coating, often with names such as "CR", SPCC, or ASTM A1008. In some cases, it may be similar in appearance to hot-rolled steel that has been pickled and oiled, but cold-rolled steel has distinctive features such as a pronounced surface finish, tighter tolerances, and increased strength (due to work hardening).
