Today's cold drawn flat steel is a type of flat steel with high precision, the material used is hardened and tempered, so it can be used directly as a shaft and does not require treatment, thus not only simplifying the process, but also cold drawing flat steel The accuracy of the quality is significantly improved, corresponding to the cold drawn flat steel is actually used to construct ordinary flat steel, the heat treatment conditions of the source are normalized, and the dimensional accuracy, and the material is ordinary, but the cold drawn flat steel The surface is very smooth and the dimensional accuracy is very high.

After the flat steel is cold drawn, there should be no cracks or local pleats on the surface. On the outer surface of the bending test, it is required that the cold drawn flat steel should be free of cracks or cracks after processing, and only use cold drawn flat steel conforming to the standard quality. Can be widely used in hardware tools and automotive standard parts, therefore, in the production of cold drawn flat steel, the choice of materials should be a reasonable requirement, then cold drawn flat steel is formed by advanced processing.
