The cold drawing process and its effects on cold drawn carbon steel
The cold drawing process increases the strength and hardness of cold drawn carbon steel, but at the same time it introduces internal stress. If there is too much internal stress, a material becomes too brittle and can break during subsequent processing. Heat treatment is the procedure that relieves internal stress and modifies the microstructure of cold drawn carbon steel. Betog Steel employs heat treatment to manage the internal stress of its cold drawn carbon steel. With the appropriate heat treatment, cold drawn carbon steel is made easier to process and to use.
Most Popular Heat Treatment Techniques for Cold Drawn Carbon Steel
The process most often associated with cold drawn carbon steel is annealing. It is the most common method used to create softer, more ductile steel. By holding the steel at the tempering temperature for a certain period, the size and overall quality of the cold drawn carbon steel can be improved. Each technique varies with regard to the desired balance of hardness, toughness and machinability. Betog Steel has three electric bullet annealing furnaces for the standard treatment of cold drawn carbon steel. The treatment enhances the areal uniformity and stability of cold drawn carbon steel.
When is Cold Drawn Carbon Steel Required to have Heat Treatment?
If cold drawn carbon steel is to be used in applications requiring high toughness and good machinability, then it requires heat treatment. It is typical for products designed to be used in the manufacture of intricate assemblies and precision mechanical components to require heat treatment. Frequently, heat treatment is required in order to relieve the high residual stresses resulting from the cold drawing process. Betog Steel offers a wide range of customized heat treatments for a variety of cold drawn carbon steel products to ensure it meets the specific requirements of the intended application.
When cold drawn carbon steel requires no heat treatment
Cold drawn carbon steel can be used without heat treatment when components of the required assembly have a simple design and low-stress structure. Components of the assembly that require high hardness and don’t involve further processing can also bypass heat treatment. For some standard components, untreated cold drawn carbon steel can be used for economical reasons. Betog Steel offers untreated and treated cold drawn carbon steel. Customers can choose untreated cold drawn carbon steel according to their needs.
Quality assurance of heat treated cold drawn carbon steel
After heat treatment, Betog Steel tests the cold drawn carbon steel to assess if the steel has the desired performance. To assess the treatment effect, mechanical properties and hardness are tested. Their production is governed by the ISO9001 quality management system to ensure the system works consistently. The combination of advanced technology and skilled personnel leads to reliable and precise heat treatment. Each batch of Betog Steel's heat-treated cold drawn carbon steel is of the same quality and can be relied upon.
