UNEDR ANNEALED CONDITION
As Cold drawn /Hot rolled /forged,in annealed condition.
Cold drawn bar: 2.2-14.2mm
Hot rolled bar: 8.0-80.0mm
Forged bar: 81.0-250.0mm
Annealing temperature:860-880 ,keep this temperature by 2-4 hours,then cooling to 600 in the speed of 20-30/h if after cold drawn precess,suggest add stress relieving annealing process Under the temperature of 600-700 ,keep this temperature by 2 hours.
Quenching & Tempering(saltbath)
Pre-heating in two steps:
Heating temperature under :400-500 and 850-900
Austenitizing temperature :1170-1190
Heating coefficient 10-15sec/mm ,quenching under 580-620 ,then cooling to room temperature.
Tempering temperature under :530-560 ,temperature 3 times, each time 1hour ,then cooling to room temperature.
1.Cutting tools in simple shape which requires high hardness,suggest adopt 1190-1200 as quenching temperature,530-540 as tempering temperture resulted in HRC 67-69.
2 .Cutting Tools in complex shape (such as milling cutter,tap)suggest adopt 1170-1190 as quenching temperature.550-560 as tempering temperature,resulted in HRC 66.5-67.5.(with Good toughness)
3 .Straightening under 200-450 after Quenching.
