1、 Different processes

Cold drawn steel is made by processing ordinary steel through cold working processes such as drawing and cold drawing, which can achieve high strength, toughness, and wear resistance of the steel. At the same time, it can also change the roughness and incompleteness of the steel surface. Ordinary steel, on the other hand, is processed through hot working processes, including forging, rolling, etc., and its surface roughness and incompleteness are relatively high.

2、 Different mechanical properties

Due to different processes, the mechanical properties of cold drawn steel and ordinary steel also differ. The tensile strength and yield strength of cold drawn steel are higher than ordinary steel. As the degree of cold drawing varies, the mechanical properties of cold drawn steel will gradually improve. At the same time, the toughness and ductility of cold drawn steel have been comprehensively improved, which can better resist impact and compression. The mechanical properties of ordinary steel are relatively balanced, but relatively low.

3、 Applicable scope varies

The application range of cold drawn steel and ordinary steel is also different. Due to its high strength, toughness, and wear resistance, cold drawn steel is suitable for fields such as mechanical manufacturing, aviation, and aerospace. The application range of ordinary steel is more extensive, including fields such as construction, bridges, and rail transit.

4、 Different structures

Cold drawn steel and ordinary steel also differ in structure. The microstructure of cold drawn steel is relatively dense without obvious grains, resulting in higher strength and better wear resistance. The microstructure of ordinary steel is relatively loose, with large and oriented grains, making it more suitable for welding and processing processes.
