Features
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 quenching good.
Typical applications
1. Mainly used as silicon steel die, for small dynamic load conditions require high wear resistance, simple shape drawing and blanking die.
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.
Delivery condition
EF or ESR, hot rolled or forged, black surface or milling.
Hardness: annealed, HB217-269
