Mechanical properties：
-hardness
Hardness of annealing: 212-241HBW.
After quenching+after recovery: After quenching and recovery, the hardness can reach 65HRC.
strength
M3 high -speed steel has high compressive strength and bending strength, and can withstand large -cutting force.
Its bending strength can reach higher levels after proper heat treatment. The specific value varies from factors such as thermal treatment process and section size.
-toughness
The M3 high -speed steel has a good toughness, the carbides are small and uniformly distributed, which helps improve its impact resistance.
In the spray forming process, the toughness and equivalent of M3 high -speed steel are excellent.
-Abrasion resistance
M3 high -speed steel has high wear -resistant particle wear, and is suitable for making cutting tools that require high wear resistance.
Its abrasion resistance is better than high -speed steel produced by traditional casting and forging processes.
-Heat resistance
M3 high -speed steel can maintain high hardness and wear resistance in high temperature environments, and has good thermal stability.
Its redness is better and can maintain performance under high temperature cutting conditions.
