What is the function of 15CrMo alloy heat treatment?

Heat treatment is an extremely effective measure to improve and improve the performance of 15CrMo alloy steel, and it plays a very important role in product reliability and economy. The heat treatment of 15CrMo alloy steel usually includes two types: ordinary heat treatment (annealing, normalizing, quenching, tempering) and surface heat treatment (surface hardening and chemical heat treatment-carburizing, nitriding, metalizing, etc.).
 
15CrMo steel application
In mechanical engineering, many machine parts, such as crankshafts, gears, camshafts of internal combustion engines, and gears in important reducers, not only require sufficient toughness, plasticity and bending strength at the core, but also require a high degree of surface thickness. Hardness, high abrasion resistance and high fatigue strength. It is difficult for the aforementioned various overall heat treatment methods to simultaneously meet the above-mentioned performance requirements, and the use of surface heat treatment is an effective method to achieve these performance requirements at the same time.
 
What is the surface heat treatment of 15CrMo alloy?
Surface heat treatment is a heat treatment method that changes the surface properties by changing the structure of the surface layer of 15CrMo alloy steel.

Surface quenching heat treatment that changes the surface structure without changing the chemical composition of the surface. It can be realized by high frequency, intermediate frequency or power frequency current induction heating or flame heating. Its common feature is that it tries to quickly heat the surface of 15CrMo alloy round steel to the quenching temperature, and when the heat has not been transmitted to the core of the part, it quickly cools down to make the surface hard, but the core still has high toughness.
Chemical treatment-a heat treatment method that changes the chemical composition and structure of the surface layer of 15CrMo alloy steel. Chemical heat treatment can be divided into carburizing, nitriding, carbonitriding, and metal infiltration according to the different infiltration elements on the surface of 15CrMo steel. It is very effective for improving and improving the wear resistance, corrosion resistance and fatigue resistance of 15CrMo steel. At present, chemical heat treatment has developed rapidly, and many new technologies have been applied.
