Cold Drawing Technology For Gost Kh12 Die Steel Production - China

GOST KH12 die steel is a type of steel used to manufacture high-strength molds and tools, possessing excellent wear resistance and resistance to thermal deformation.

Regarding its cold drawing technology, the following are some key points: 1 - Material Preparation: Before cold drawing, ensure the surface of the KH12 steel is clean, free of oil and rust, to avoid affecting the cold drawing effect.

2 - Cold Drawing Process: - **Heating**: Although called "cold drawing, " in actual operation, GOST KH12 die steel may be slightly heated to improve plasticity and reduce stress during the cold drawing process.

- **Drawing**: Using a specialized cold drawing machine, the steel is stretched to the required diameter and length through a die.

During this process, the material undergoes plastic deformation, leading to an increase in its strength and hardness.

- **Cooling**: After drawing, the cooling rate must be controlled to prevent excessively rapid cooling that could cause the material to crack.

3 - Deformation Characteristics: During the cold drawing process, the grain size of the KH12 steel is refined, improving the material's mechanical properties.

Meanwhile, cold drawing can lead to uneven stress distribution, requiring appropriate stress relief treatment to release internal stress.

4 - Post-treatment**: After cold drawing, heat treatment (such as tempering) is usually performed to adjust the material properties and bring it to its optimal performance.

During the cold drawing process of GOST KH12 die steel, parameters must be carefully controlled to ensure product quality and performance.

In practical applications, companies can optimize and adjust the cold drawing process according to specific needs.
