Micro-alloying of Alloy Steel Used in Automobile Spring
The micro alloying elements Nb and V were added into the alloy steel 60Si2 Mn used in automobile spring, and the microstructure, mechanical properties, wear resistance and corrosion resistance were investigated. The results show that the mechanical properties, wear resistance and corrosion resistance of the alloy steel 60Si2 Mn are improved after adding trace elements Nb, especially compound adding trace elements Nb and V.
