DCMX
DCMX is a matrix-type cold work tool steel
DCMX is a matrix-type cold work tool steel: only fine carbides are distributed in matrix due to optimum alloy design and production process.
DCMX shows high performance in service and ease in mold making as well.
Applications include:
Punches
Dies
Working Tools for Cold Pressing and Cold Forging
Cold Stamping Dies for High Strength Steels
Insert Blocks for Composite Stamping Dies
Blanking Punches and Trimming Edges
- High hardness such as 62 HRC is available by high temperature tempering with good dimensional stability, resulting in high wear resistance
- High toughness helps to prevent cracking and chipping.
- Isotropic dimensional change works easy geometry control in heat treating.
- Machinability is improved by free machining additives and finely dispersed carbides.
