Hardness ranges from HRA 86 to 93, equivalent to HRC 69 to 81, with wear resistance 4 to 7 times higher than that of high-speed steel. This ensures that the cutting edge maintains dimensional stability and remains sharp for an extended period during high-speed cutting.
Excellent red hardness:
The material maintains a high hardness (approximately 60 HRC) even at high temperatures of 900–1000°C, enabling stable operation under harsh conditions involving high temperatures and high speeds.
