D3 cold work tool steel bar is a kind of high-carbon, high chromium
austenitic steel with high wear resistance, hardenability,
toughness, thermal stability, compressive strength,
micro-deformation and other characteristics.
D3 tool steel bar is a comprehensive performance, with good
machinability and thermal oxidation resistance of cold die steel.
Wide adaptability, high wear resistance, three to four times higher
than the average low alloy tool steel, dimensional stability after
1. Mainly used as silicon steel die, for small dynamic load
conditions require high wear resistance, simple shape drawing and
2. For the manufacture of bending mode requires high
wear-resistant, complex shape of the punch, die, insert, do punch,
die when the proposed hardness of 60 ~ 64HCR.
3. For the production of drawing die wear-resistant die, the
proposed hardness 62 ~ 64HCR.
4. For cold extrusion die punch aluminum, the proposed hardness of
60 ~ 62HCR.
5. For bending the carbon content of 0.65% ~ 0.80% of the bomb
construction steel, hardness 60 ~ 62HCR.
6. Can be used for blanking die, punch, rolling wheel, scissors,
cold pier mold, clay mold.
7. Can be used for thermosetting plastic molding and so on.
EF or ESR, hot rolled or forged, black surface or milling.
Hardness: annealed, HB217-269
