Heat Treatment

Heat treatment is a critical and highly specialized process used to enhance the mechanical properties and performance of metal castings and forgings. By applying precise control of temperature and cooling rates, heat treatment can optimize key characteristics such as strength, hardness, toughness, wear resistance, and fatigue life. Our heat treatment services cater to a wide range of industries, ensuring that each part achieves the desired physical and chemical properties to meet demanding operational requirements.

Our company offers a comprehensive suite of heat treatment services for castings and forgings, aimed at improving the performance, durability, and consistency of components used in diverse sectors such as automotive, construction machinery, heavy machinery and oil & gas, windpower etc. With our advanced equipment and expertise, we ensure that every piece is treated with the utmost precision, providing a reliable solution for high-stakes applications.

Annealing Heat Treatment Annealing is a crucial heat treatment process used to modify the physical and mechanical properties of castings and forgings, ensuring that they meet the desired specifications for their intended applications. This process involves heating the material to a specific temperature and then allowing it to cool slowly, which results in the reduction of internal stresses, improvement in ductility, and refinement of the microstructure. In the context of castings and forgings, annealing enhances material performance by improving machinability, reducing brittleness, and ensuring uniformity in the final product. Learn More >

Normalizing Heat Treatment Heat treatment Normalizing is a kind of heat treatment to improve the toughness of steel. After the steel members are heated to 30-50 ℃ above Ac3 temperature, they shall be kept for a period of time. Learn More >

Quenching & Tempering Heat treatment quenching&tempering The purpose of quenching is to transform the undercooled austenite into martensite or bainite to obtain martensite or bainite structure, tempering at different. Learn More >

Induction Hardening Heat Treatment Induction hardening is a localized heat treatment process used to selectively harden specific areas of castings and forgings, enhancing surface properties such as hardness, wear resistance, and fatigue strength, while maintaining the toughness and ductility of the core material.
