Conclusions
-
1.
Annealing (at 825–900°) for 24 h for hot-rolled and 15–18 h for cold-rolled high-speed steel lowers the quench hardness, secondary hardness, and red hardness. These properties are much more impaired after annealing at 900° than at 825°.
-
2.
The effect of annealing depends on the amount and composition of M6C carbide, i.e., the chemical composition of the high-speed steel. The properties are most impaired for steel R18, where the carbide contains more tungsten, and less impaired for steels R12 and R6M5.
-
3.
It is recommended that the annealing temperature not be higher than 850–860°, that the load in the furnace be limited so that the annealing time at temperatures over 800° does not exceed 10–18 h, and that the annealing time be still shorter for cold-rolled steels.
