M2 high-speed steel features excellent hardness (62-64 HRC) and superior wear resistance. It performs reliably under high temperatures, shock, and vibration, extending tool life.
Ordinary HSS often suffers from edge chipping and short tool life during frequent or continuous cutting. M2 steel, with more uniform carbide distribution and higher toughness, improves cutting stability, reduces tool changes, and lowers overall cost.

Hardening and tempering of M2 high-speed steel have played an important role in improving its hardness, wear resistance. and toughness. The typical heat treatment for M2 high-speed steel generally follows an Anneal, Quench, and Temper process scheme. Here is the detailed explanation for each step:
Basically, to softens the steel by relieving stress and making it easier to machine.
A process of heat treatment to increase hardness and wear resistance by rapidly cooling the steel.
When using M2 steel, tempering follows quenching in order to relieve stress and fine-tune hardness and toughness for optimum performance.
The following properties can be obtained after proper heat treatment on M2 high-speed steel:
Very Strong Hardness:
Hardness 62-64 HRC, Shape cutting tasks.
Fantastic Wear Resistance:
The quenching and tempering process puts them in a condensed matrix, very suitable for high-frequency and long-term cutting.
The tempering process eliminates internal stress, increases impact resistance for complex machining and heavy-duty applications.
