Abstract
A kind of bainite casting steel with low alloy,high intensity and high toughness is analyzed,this compound phase microstructure is mainly made up of bainite with a little martensite,which is obtained by necessary tempering treatment based on different working condition during continuous air cooling to room temperature.Different heat treatment process shows that comprehensive mechanical properties are improved with constantly changing austenitizing temperature,bainite cast steel has best intensity and toughness at 1040℃.
