What are the characteristics of forging process of high temperature alloy steel?

Forging of high-temperature alloy steel is a special metal processing technology, which is used to manufacture parts with high temperature resistance, corrosion resistance and high strength requirements. The main features of forging process for high temperature alloy steel are as follows:

High forging temperature: Compared with traditional carbon steel forging, high-temperature alloy steel forging needs to be carried out at higher temperature. Generally, the forging temperature should be higher than the recrystallization temperature of the alloy to ensure that the alloy has sufficient plasticity and fluidity. This also helps to reduce the stress and deformation in the forging process.

Complexity and challenge: High temperature alloy steel has complex chemical composition and microstructure, which contains many alloying elements. Therefore, it is very important for technicians to understand the characteristics and behavior of materials and choose appropriate parameters during forging. At the same time, due to the high hardness and melting point of the alloy, the forging process requires a relatively large impact force and forging equipment.

Precision control: In the forging process of high-temperature alloy steel, it is necessary to accurately control the forging temperature, cooling rate, strain rate and deformation. This is because the change of microstructure of the alloy will directly affect the mechanical properties and heat resistance of the final product. Therefore, forging technologists need to use advanced temperature control equipment and precise measuring instruments to ensure the consistency of quality.

Heat treatment requirements: High temperature alloy steel usually needs heat treatment after forging to further adjust its structure and properties. The heat treatment process includes annealing, quenching and tempering, aiming at reducing internal stress and improving the strength and hardness of the material.

High-cost material: high-temperature alloy steel is a high-cost material, which is usually used in extreme working conditions. Therefore, it is very important to control the utilization ratio of materials and waste materials in the forging process of high temperature alloy steel. While saving materials, we must also ensure that the quality and performance of products meet the requirements.

In a word, the forging of high-temperature alloy steel is a complex and challenging process, which requires forging technicians to have in-depth material knowledge and rich experience. By accurately controlling forging parameters and proper heat treatment, high-quality high-temperature resistant parts can be produced to meet the demand of modern industry for high-performance materials.
