What are the precautions for tempering steel

Tempering treatment of steel is a heat treatment process that aims to change the structure of steel through heating and heat preservation to eliminate residual stress and improve the toughness, hardness, and other properties of steel. When tempering steel, you need to pay attention to the following aspects:


1. Temperature control: Tempering temperature is a key parameter and different types of steel need to be tempered in different temperature ranges. The appropriate tempering temperature needs to be selected based on the type of steel, the shape of the workpiece, and the required properties.

2. Holding time: Maintaining appropriate holding time is the key to ensuring uniform tempering of steel. If the holding time is too short, the tempering effect will be poor, and if it is too long, the performance of the steel may be reduced.

3. Cooling method: Steel needs to be properly cooled after tempering, generally using air cooling or oil cooling. If the cooling rate is too fast or too slow, it will hurt the performance of the steel. It is necessary to choose the appropriate cooling method according to the specific situation.

4. Prevent oxidation: During the tempering process, attention should be paid to preventing oxidation of the steel surface. Appropriate atmosphere protection or coating measures can be taken to ensure that the quality of the steel surface is not affected.

5. Ensure process specifications: When performing the tempering treatment, the process specifications and operating procedures must be followed to ensure that each step is correctly executed to ensure that the steel meets the expected performance requirements.


In general, the tempering treatment of steel is a relatively important heat treatment process. Appropriate treatment parameters and methods need to be selected according to the specific steel materials and requirements to ensure that the steel can obtain ideal properties.
