Dalian Maritime University successfully studied “marine diesel injector nozzle and pump sleeve plunger heat treatment process”, April 17 adopted by the Ministry of Communications presided over the technical appraisal. The process creatively combines the overall toughening heat treatment with the surface toughening heat treatment. After the new process of marine diesel fuel injection nozzle and pump sleeve plunger to pay, by the Shanghai Maritime Bureau real machine use, its life expectancy exceeds the current introduction of an internationally renowned brand more than doubled. The process is also generally applicable to die steel processing, can be wide
