The steel quenching process is mainly used in cast steel. When the steel is heated to the maximum temperature it can withstand, all the original room temperature will be converted into austenite. The steel will be immersed in oil or water to cool. Austenite transforms into martensite. Rapid cooling during quenching will produce a certain amount of internal stress inside the section steel. To a certain extent, the medium-section steel will be distorted and even cracked. Therefore, a suitable cooling method must be selected. The quenching process of section steel is mainly It is divided into single liquid quenching, double medium quenching, martensite graded quenching and bainite isothermal quenching.
The cooling medium for quenching steel can become martensite when it is quenched, but it will not cause too much stress. After the steel metal is processed and heated to a certain temperature, it is immersed in a quenching medium for rapid cooling. The commonly used quenching medium is mainly water, salt water, mineral oil and air. The hardness, strength and wear resistance of the metal can be improved through the quenching process. The good characteristics make it Section steel is widely used in various tools, molds and measuring tools. Quenching and tempering of section steel improves its chemical properties and enhances its corrosion resistance.
The future development of section steel will continue to accelerate. Although the section steel market this year was once weak, the future section steel market is unpredictable. Maybe after the section steel market hits the bottom, it will usher in another situation.
