  • How to maintain the turbocharger of the shaft? 2019-02-12

    The turbocharger is classified as a high temperature component, because the gas that drives it runs directly from the exhaust gas discharged from the cylinder, the temperature can be as high as 900 ℃ -1000 ℃, and under full load, the speed of the turbine can reach 180,000-200,000 per minute Therefore, the efficient and stable smooth oil can be directly reflected from the engine. The existence of turbocharging has higher requirements for maintenance than ordinary cars.

  • Analysis of the basic composition of the shaft material 2019-01-29

    The corrosion resistance of these steels comes from "chromium", which ranges from 11.5 to 18%. The higher the chromium content, the higher the carbon content to ensure the composition of martensite during heat treatment. The above three types of 440 stainless steel are very It is rarely considered as an application requiring welding, and the 440 type of molten metal is not easy to obtain.
