DCMX

Description

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

Unique Characteristics

• 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.
