摘要: 采用JMatPro软件对比研究了两种抽油杆钢不同温度下的平衡相及其成分.结果表明,与7Mn2SiCr钢相比,12MnSi2Cr钢铁素体、奥氏体相中将固溶更多的Cr,Mo,Si元素,而碳化物总量减少了30%,微合金元素Nb的加入提高了钢中M(C,N)碳化物的稳定性.在此基础上,对12MnSi2Cr抽油杆钢的高韧性进行了探讨.

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.
