35CrMo4 Steel Application and Machining

35CrMo4 steel is often used in the manufacture of high-strength and high-wear parts such as braking systems, steering systems, and suspension systems in the automotive industry. In addition, it can also be used in the manufacture of engine components. The advantages of 35CrMo4 steel in the automotive industry include high strength, good fatigue resistance, good toughness, and wear resistance. It can be used to manufacture high-load components such as engine parts, gearboxes, and drive shafts. At the same time, because of its good weldability and processability, it is also widely used in the manufacture of structural parts such as shock absorbers, steering arms, and vehicle frames.

35CrMo4 steel is often used to manufacture parts with high strength, high hardness and high wear resistance, such as shafts and gears. In machining, the following items need to be paid attention to:

1. Select the appropriate cutting parameters, including tool material, edge angle, feed rate and depth of cut, etc.

2. Control the processing temperature to avoid material deformation or surface quality degradation caused by excessive temperature.

3. Maintain sufficient lubrication and cooling during machining to improve cutting efficiency and prolong tool life.

4. Pay attention to remove the burrs and scratches produced by processing to ensure the precision and surface quality of the parts.

5. Before heat treatment, pretreatment should be done, such as annealing, normalizing and quenching, etc., to ensure that the performance of the parts meets the requirements.

6. Make sure the processing equipment and tools are in good condition, check and maintain them regularly.

35CrMo4 steel is an alloy structural steel with excellent mechanical properties and heat resistance, which is widely used in engines, steering systems, transmission systems and other components in the automotive industry. In the future, with the continuous development of the automobile industry and the improvement of material performance requirements, the application prospect of 35CrMo4 steel in the automobile industry is still broad. At the same time, its sustainability and environmental protection will also become important considerations.
