 WHAT’S THE HEAT TREATMENT PROCESS IN THE PROCESS OF CUTTING PICKS BLADE PRODUCTION?

42 CrMo material blade of conventional heat treatment process for: + 360 ~ 400  840  oil quenching tempering.

35 CrMnSi material blade of conventional heat treatment process for: + 380 ~ 430  880  oil quenching tempering. Conditional manufacturer also can be used 880  heat insulating + 280 ~ 320  isothermal quenching, and then air cooling heat treatment process.

Si - Mn - Mo quasi bainite steel USES is: 880  normalizing + tempering heat treatment process. After heat treatment can be obtained by bainite ferrite and retained austenite, composed of quasi bainite, with good tenacity and high wear resistance.
