1、 Increased intensity

The strength of steel refers to its tensile strength, which is one of the important indicators for measuring the performance of steel. Compared with hot-rolled steel, cold-rolled steel has higher tensile strength. Cold drawing process can make the internal grains of steel finer, more complex, and significantly improve strength.

2、 Increased hardness

The hardness of steel after cold drawing is significantly higher than that of hot-rolled steel, due to the changes in the macroscopic shape and microstructure of the steel during the cold drawing process. Cold drawing process can make the grains of steel more dense and the grain boundaries clearer, thereby improving hardness and making the steel more durable.

3、 Improved wear resistance

Compared to hot-rolled steel, cold-rolled steel also exhibits good wear resistance. Cold drawing process can make the surface of steel more flat and smooth, greatly reducing the occurrence of surface defects and oxide layers, and improving the wear resistance and service life of steel.

In summary, the steel after cold drawing has significantly improved in strength, hardness, and wear resistance. With the increasing demand for steel, cold drawing technology will also be widely applied and promoted, bringing more possibilities for the production and application of steel.
