Abstract: Equilibrium phases and their compositions under different temperature are studied in two sucker-rod steels with JMatPro software. Compared with those in 17Mn2SiCr steel, more alloying elements of Cr, Mo and Si are saturated in austenite and ferrite respectively, while the amount of carbides decreases by about 30% in 12MnSi2Cr steel. Stability of M(C, N) carbide is increased by the addition of micro alloying element Nb. Based on this study, high toughness of the sucker-rod of 12MnSi2Cr steel is discussed.

Key words: alloying element, sucker-rod
