W6Mo5Cr4V2 | M2 | S-6-5-2 (1.3343) | SKH51 |
Advantages:
M-2 is the most widely used high speed steel for general purpose cutting applications. With a high working hardness, M-2 has an optimum combination of wear resistance and toughness, making it desirable for non-machining applications such as punches, die buttons, cold heading inserts and cold forming rolls.

M2 | 0.80-0.90 | 0.15-0.40 | 0.20-0.45 | 3.80-4.40 | 4.50-5.50 | 1.75-2.20 | 5.50-6.75 | ≤0.03 |
Very high red hardness.
Excellent wear resistance.
High hardening response.
Machinability:
The machinability of fully annealed M-2 is rated at 55% of a 1% carbon tool steel. It also has a low to medium grindability.
