Heat treatment of steel is a technology that changes the physical and chemical properties of steel to achieve certain process effects by controlling temperature, time and environment. Heat treatment of steel can enhance the strength, hardness, toughness, wear resistance and corrosion resistance of steel. It can also change the structural structure of steel and reduce internal stress, thereby improving the service life and reliability of steel.

Generally speaking, the heat treatment of steel includes three processes: heating, holding and cooling. The temperature, time and atmosphere of each process are determined based on the properties of the steel, process requirements and equipment conditions. For example, for the quenching treatment of carbon steel, the temperature is generally between 860-920°C. The holding time is usually between 1-2 hours depending on the thickness and specifications of the material. The cooling method can be water quenching, oil quenching or salt bath quenching. wait.

The heat treatment of steel is an indispensable and important link in the steel processing and manufacturing process. It plays a decisive role in improving the performance of steel and improving the quality and reliability of steel. At the same time, the heat treatment process is also a professional technology that requires rich experience, professional knowledge and excellent skills to master. Therefore, when performing heat treatment of steel, we need to carefully analyze and evaluate each process parameter to ensure the quality and effect of the steel.
