Surface Treatment of Precision Steel Pipe
Surface treatment of precision steel pipe is by changing the precision steel surface tissue heat treatment to alter one surface properties.
Surface hardening eleven surface structure change, without changing the chemical composition of the surface heat treatment. It can be used high-frequency, intermediate frequency or frequency currents induction heating or flame heating ways. Their common feature is to try precision steel surface is rapidly heated to the quenching temperature, and when the heat has not yet spread to parts of the heart unit, then rapidly cooled, so that high surface hardness, toughness and heart Ministry still high.
Changes in heat treatment chemical treatment eleven precision steel surface chemical composition and organization occurred. Chemical treatment in accordance with precision steel tubes penetrate the surface of the different elements can be divided into carburizing, nitriding, carbonitriding, alloying and other methods. Enhance and improve its precision steel wear resistance, corrosion resistance, fatigue resistance is very effective. To the current rapid development of chemical treatment, the application of many new technologies.
In mechanical engineering, a lot of machine parts, such as the crankshaft of the internal combustion engine, gears, cam shaft and the gear reducer is important, not only requires core section has sufficient toughness, ductility and flexural strength, and requires a certain thickness of the inner surface of a high hardness, high wear resistance and high fatigue strength. The foregoing various overall heat treatment is difficult to simultaneously satisfy the above performance requirements, while the use of surface heat treatment is the most effective way to achieve these performance requirements.
