M2 tool steel

High speed special tool steel

M2 steel (otherwise W6Mo5Cr4V2  or the same as 1.3343) is a high speed steel in tungsten-molybdenum series.

The carbides in it are small and evenly distributed. It has high wear resistance. After heat treatment, its hardness is the same as T1, but its bending strength can reach 4700 MPa, and its toughness and thermoplasticity are higher than T1 by 50%.

It is usually used to manufacture a variety of tools, such as drill bits, taps and reamers.

M2 Chemical Composition

Carbon – 0.85%
Chromium – 4.1%
Molybdenum – 5%
Vanadium – 1.8%
Tungsten – 6.4%
