| Abstract: | Combined with the calculation of Jmatpro software and a large number of trial production, the new type of high temperature resistant stainless bearing steel 6Cr15Mo4VN was developed. DSC analyzer, optical microscope and EPMA were used to study the microstructure and properties of 6Cr15Mo4VN nitrogen- containing bearing steel. The results show that the microstructure of quenched- tempered sample is tempered martensite + carbide + residual austenite, which primary carbide is zonal distribution with an acceptable size, fine carbide is uniformly distributed in martensite matrix. The steel gets lower hardness after annealing and becomes very hard after quenching- tempering, which shows excellent properties for bearing. In 40 mass% nitric acid solution, almost no corrosion occurs. In 10 mass% hydrochloric acid solution, the corrosion resistance property is superior to 9Cr18Mo and 7Cr14MoN. |
