Features
Hot rolled D3 is the best wear-resistant alloy steel.
Heat treatment effect is stable.
Resistance welding electrode: Chromium zirconium copper through the combination of heat treatment and cold work to ensure performance, it can get the best mechanical properties and physical properties.
High carbon, high chromium type ledeburite cold work tool steel, has good hardenability and good wear resistance.
Features and Scope: It is a widely used cold work die steel, with high strength, good hardenability and good wear resistance, but poor impact toughness.
Mainly used to bear the impact load is small, requiring high wear-resistant die and punch, cold cut scissors, drill sets, gauges, drawing die, die stamping, rolling plate, drawing die and thread rolling die.
Applications
| Mainly used as silicon steel die, for small dynamic load conditions require high wear resistance, simple shape drawing and blanking die. |
| For bending the carbon content of 0.65% ~ 0.80% of the bomb construction steel, hardness 60 ~ 62HCR. |
| Can be used for blanking die, punch, rolling wheel, scissors, cold pier mold, clay mold. |
| It is recommended to make punch, die and insert with high wear-resistant and complex shape in bending die. It is recommended when making punch and die. The hardness is 60 ~ 64HCR. |
| For cold extrusion die punch aluminum, the proposed hardness of 60 ~ 62HCR. |
| For the production of drawing die wear-resistant die, the proposed hardness 62 ~ 64HCR. |
| 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
