TOOTH MATERIALS

CONVENTIONAL M42

Good heat treatment ensures fine microstructure of M42 high speed steel,offering great wear resistance and longer band life.

WEAR RESISTANCE：★★★
CHIPPING RESISTANCE：★★★
POWDER METALLURGY M42

The M42 high speed steel manufactured by powder metallurgy has finer and more homogeneous carbides distributed on martensite matrix,providing better combination of wear resistance and toughness.

WEAR RESISTANCE：★★★★
CHIPPING RESISTANCE：★★★☆
POWDER METALLURGY M51

M51 powder metallurgy high speed steel with higher Co and C contents has finer and more carbides,which offers better wear resistance and red hardness than M42,which is more suitable for hard-to-machine materials.

WEAR RESISTANCE：★★★★★
CHIPPING RESISTANCE：★★★
