Will air-harden in smaller sections. Low distortion
if air hardened, but larger sizes quenched in oil may distort. More resistant
to abrasion and corrision than 2767. Smaller/medium sizes may be vacuum
treated. May be used for large tools. |

Tougher than M42, but will not develop ulta high
hardness. Will accept high polish. May be vacuum treated. Distorts less
than T1 |

| T1 High speed steel for general use |
Similar to M2 but higher 'red' hardness and abrasion
resistance. May be vacuum treatred. High hardening temperature leads to
risks during heat treatment and increased chance of distortion. |
