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 soften 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.
Strictly control the cooling speed at quenching, to avoid true hardness unevenness or cracking caused by too fast or too slow cooling.
At least two tempering cycles, then internal stress will be fully released, and also improve toughness.
Keep the temperature under control within reasonable bounds during the whole heat treatment,do not allow to go critical condition that will cause the grain coarsening or performance degradation.
Better value for money
M2 high-speed steel, the same quality but competitively priced: We are able to offer similar quality to Japanese, European, and American brands at a lower price. It does so through exacting smelting and rigid quality control.
EAF+LF+VD+RS ESR, with more uniform microstructure and finer carbide particles, thus better toughness and wear resistance.

Our unique technology:
In line with our own actual conditions, we have developed a domestically unique rapid solidification electro-slag remelting (RS ESR) process (joint research with Shanghai University and Beijing Iron & Steel Research Institute), which can effectively improve the purity and carbide distribution of materials.
In collaboration with Baosteel Group, we innovated the proprietary powder injection molding of Spray Forming High-Speed Steel, which only our factory in China can implement.
Applicable to the production of drill, tap, screw die, milling cutter, gear cutter, cold die mold and other cutting tools, and molds with high wear resistance and strength.
Heavy-Duty Molds
For punch dies, cold extrusion dies, and forming molds under heavy loads and high-wear conditions.
What differentiates M2 high-speed steel from other high-speed steel?
M2 high-speed steel has better toughness, impact, and vibration resistance than other high-speed steel types, and has a more uniform carbide distribution. Moreover, it also has good wear resistance, which is why it is ideal for manufacturing cutting tools with high performance.
