Heat treatment:

quenching temperature 820 ℃ ~ 870 ℃, water-cooled, tempering temperature 550 ~ 650 ℃,


Application:

Widely used in machinery manufacturing, this grade has good mechanical properties. But this is a medium carbon steel, Quenching performance is not good, this grade can be quenched to HRC42 ~ 46. if need a good surface hardness, and also need superior mechanical properties, usually do surface carburizing, so this can get the required surface hardness.
