The heat treating process of leaf-minimum plate spring of 50CrV steel instead of 52CrMnBA steel for heavy truck was investigared .The results reveal that the hardenability and hardness uniformity of 50 CrV steel plate spring may be significantly increased by quenching in a PAG aqueous solution , and that the fatigue life of plate spring assembly is as long as over 120 000 cycles , conforming with the technical requirement .Furthermore , the road test shows that the 50 CrV steel leaf-minimum plate spring for heavy truck has satisfactory performance , and is more low in production cost .
