The Influence of Sub-temperature Quenching Temperature on Microstructure and Properties of 60Si2Mn Steel

摘要：

Influence of sub-temperature quenching temperature on the tensile strength , hardness and toughness of 60Si2Mn steel was studied, and the ferrite content, austenite grain size and martensite morphology of the microstructure of this steel after sub-temperature quenching were analyzed. The results show that duplex microstructure of martensite and ferrite is obtained by sub-temperature quenching of 60Si2Mn steel. With the quenching temperature increasing, the ferrite content decreases, the strength and hardness of the 60Si2Mn steel increase, while its toughness decreases in the range of 770～810℃. The maximum of strength and hardness can be obtained by quenching at 800℃,but they decease above 800 ℃.The small amount of strip ferrite is distributed among martensite lamellar to improve the toughness of the steel. All martensite structure can be obtained by quenching at 810 ℃.
