Heat Treatment：

Annealing

1.1.3343/HS6-5-2C must be annealed after hot working and before re-hardening.
2.Heat the temperature to 850°C at a rate of no more than 220°C per hour.
3.Hold at the temperature for one hour per inch of thickness(at least two hours).
4.Cool slowly in the furnace or in air to ambient temperature.
5.The resultant hardness achieved should be Max 248HBW or lower.’

Hardening

1.Preheat 1.3343/HS6-5-2C to 450-500°C .then up to 850-900°C.
2.Heat to the final hardening temperature of 1200-1250°C and make sure the material must be heated through.
3.Quench in warm oil or brine,and then complete the quench in air.(care must be taken at this step)
4.1.3343/HS6-5-2C high speed steel is suitable for vacuum hardening.

Tempering

1.Tempering must be done immediately after quenching.
2.Heat thoroughly and uniformly to the tempering temperature.
3.Hold at the temperature for at least two hours (one hour per inch of the total thickness).
4.Double tempering is required.
