Cr12MOV D2 1.2379 SKD11 Cold Work Mold Steel Flat Bar
Description
2
Pre-hardened plastic mould steels are widely used for manufacturing
mould for plastic because of their four main properties and
characteristics:
(1) Wear Resistance;
(2) Corrosion Resistance;
(3) Mirror Finishability;
(4)Surface Workability.
These steels are quenched and tempered before being manufactured
into mould for plastic, therefore the deformation and cracking of
mould resulted from heat treatment can be avoided.
1, Features
A, Good heat-resistance and fatigue-resistance.
B, Good cutting and polishing performance.
2, Application
Used for making hot squeeaing mould,forging mould and embedded
lump.
A, Suitable to manufacturing aluminum, zinc, copper alloy extrusion
die, die casting, hot forging die and hot shear blades, etc.
B, Extrusion mold of aluminum and magnesium, die-casting mold,
especially adapt to the mold in large and complicated form.
C, Extrusion mold of copper alloy, die-casting mold

Advantage
1.Higher hardness than D2 after heat treatment.
2.Twice the toughness of D2 with superior wear resistance.
3.Substantially higher fatigue strength compared to D2.
4.Smaller primary carbides than D2 protect the die from chipping
and cracking.
5.Secondary refining process (DLF) reduces impurities.
6.Machines and grinds up to 40% faster than D2.
7.Less residual stress after wire EDMing.
