Study On Structure Property Of Superpower Oil Engine Austenite Exhaust Valve Steel-3Cr23Ni8Mn3MoN

For the material 4Cr14Ni14W2Mo ,5Cr21Mn9Ni4N and 3Cr23Ni8Mn3MoN, the analysis of their mechanical property, microstructures and heat treatment. Discover the 3Cr23Ni8Mn3MoN organizes of indoor temperature after passing by the heat temperature , the mechanics function of the heat temperature bottom and the anti-corrosion the function is better than the 4Crl4Nil4W2Mo and 5Cr21Mn9Ni4N. Then it also can satisfy with the need of exhaust property . Because of a wide solid dis-solving treatment , the 3Cr23Ni8Mn3MoN with good heat treatment is hard to overheat and over-sinter. And the 3Cr23Ni8Mn3MoN has more chromium , more nitrogen and less nickel element .Holding steady austenite structure , it promotes the high-temperature intensity and anti-corrosion function and saves the nickel element ,which accord with our country minerals resource and reduce the cost of original material . So it can instead of the 4Cr14Ni14W2Mo and 5Cr21Mn9Ni4N to be new steel used in Superpower Oil Engine production...
