| Abstract: | In attempt to develop better materails than 38CrMoAlA steel and GCr15 steel applicated for diesel engine plunger bushing,a new kind nitriding steel 25Cr5MoA was studied .In the first place,the chemical compositions of 25Cr5MoA steel were analysed and determinded,then some the material was obtained through electrosmelting.Its CCT curve was determined by test.The influence of quenching and tempering temperature on the mechanical properties was also studied.The results show that the steel has superior hardenablity and good comprehensive properties. |
