Introduction of quenching process for (sus) C-section steel fittings-weiwu

Our company is a professional manufacturer of (sus) C-section steel fittings. We have many years of experience in production and sales. Now we are going to learn the quenching process of (sus) C-section steel fittings together.

(sus) C-section steel parts quenching process is mainly used for steel parts. When commonly used steel is heated to above the critical temperature, the original structure at room temperature will be all or most transformed into austenite. Then steels will be immersed in water or oil for rapid cooling, austenite will be transformed into martensite. Compared with other structures in steel, martensite hardness is higher. Rapid cooling during quenching will cause internal stress in the workpiece, when the steel is immersed in water or oil, austenite will be transformed into martensite. The workpiece will distort or even crack when it reaches a certain degree. Therefore, suitable cooling methods must be selected. According to the cooling methods, the quenching process of C-section steel can be divided into four categories: single-liquid quenching, double-medium quenching, martensite stepped quenching and bainite isothermal quenching.

(sus) C-section steel fittings are heated to a suitable temperature and kept for a period of time, then immersed in the metal heat treatment process of rapid cooling in quenching medium. Commonly used quenching medium is brine, water, mineral oil, air, etc. Quenching can improve the hardness and wear resistance of metal workpieces, so it is widely used in various workpieces, dies, measuring tools and parts requiring surface wear resistance (such as gears, gears, etc.). Rollers, carburized parts, etc. By quenching and tempering at different temperatures, the strength, toughness and fatigue strength of metals can be greatly improved, and the combination of these properties (comprehensive mechanical properties) can be obtained to meet different application requirements. In addition, quenching of (sus) C-section steel fittings can also make some special properties of steels obtain certain physical and chemical properties, such as quenching to enhance permanent magnet steel. Its ferromagnetism and stainless steel improve its corrosion resistance.
