ANNEALING |
||
| Tools should be
protected from excessive scaling or decarburisation by packing in a suitable inert material in a sealed container. Heat to 770°C / 790°C and hold for sufficient time to ensure uniformity then cool slowly at 20°C per hour to 650°C . The tools may then be withdrawn and air cooled. This treatment should result in a hardness of 229 HB maximum. |
