摘要
35VS钢以中碳结构钢(40钢)的成分为基,加入微量合金元素钒,通过V(C,N)弥散强化作用,在热轧空冷或热锻控冷条件下,综合力学性能及使用性能达到了国内调质40钢及国外同类钢(日本 MF40钢)的水平。加入适量易切削元素硫,其切削性比调质钢优异。35VS 钢成功地取代调质40钢制造汽车及空压机的发动机连杆。
35VS steel is designed by adding a small amount of V and S to the medium carbon steel40.This steel is essentially strengthened by V(C,N)precipitated during subsequent air coolingfrom hot forging or rolling of steel.It has the same mechanical properties as those of both theMF 40 steel in Japan and the quenched and tempered steel 40 in China.It also possesses bettermachinability than the latter.It has been successfully used to make the connecting rods of auto-mobile and air compressor.
