Core Performance Characteristics
High Hardness Support: Maintains stable high hardness (HRC 58–65) at room temperature, ensuring the die does not deform under high stress and preserving machining precision.
Excellent Wear Resistance: Utilizes alloying elements such as high carbon and chromium to form stable carbides, significantly reducing the wear rate of working surfaces and extending the die's service life.
High Hardenability and Crack Resistance: Hardens via air cooling with excellent hardenability; significantly reduces the risk of quenching cracks in large dies and meets the requirements for machining dies with complex cross-sections.
Fatigue and Impact Resistance: Offers strong resistance to crack propagation and multi-impact fatigue, enabling the die to withstand cyclic loads during cold-working processes and reducing the probability of brittle fracture failure.
Practical Application Functions
Sheet Metal Blanking: Used to manufacture punches and dies for blanking and punching metal or non-metal sheets, controlling burr height and ensuring high-quality cut edges.
Cold Forming Operations: Suitable for processes such as cold deep drawing, cold extrusion, cold heading, and coining; enables cold plastic forming of workpieces across a range of material hardness and thickness levels.
High-Precision, Long-Life Performance: Designed for high-volume production scenarios (millions of units); proper grade selection ensures stable, long-term operation and reduces the frequency of die repair and replacement.
Process Compatibility: Compatible with surface treatments such as PVD coating and cryogenic treatment; these processes further reduce working-surface friction, prevent workpiece scoring, and provide an additional boost to the die's service life.
