How to Choose the Tungsten Carbide Grade for Cold Heading Dies
Custom cold heading dies are typically manufactured using tungsten carbide grades with properties similar to ISO K-series, with a strong focus on hardness, compressive strength, and resistance to impact and cracking. Unlike wear-focused components such as bushings or nozzles, cold heading dies operate under extreme compressive stress and repeated impact during high-speed forming processes.
Depending on application conditions, such as material type (e.g., steel, stainless steel), forming pressure, part geometry, and production volume, different cobalt binder contents (e.g., K10–K40 equivalent) are selected to balance hardness and toughness. Lower cobalt grades provide higher hardness and wear resistance for less demanding forming operations, while higher cobalt grades offer improved toughness and resistance to chipping, cracking, and premature failure under heavy impact and high-load conditions.
Corresponding Chinese tungsten carbide grades. For example, K10 corresponds approximately to YG6 (high wear resistance), K20 to YG8 (general purpose), and K30–K40 to YG10–YG15 (higher toughness grades). Final grade selection depends on wear conditions, impact load, and service life requirements.
K10, K15, K20, K30, K40 Grade Equivalency Table (YG6, YG8, YG10, YG15)
| ISO Grade | General Characteristics | Common Chinese Grade Reference |
|---|---|---|
| K10 | High hardness, low cobalt content, excellent wear resistance | YG6 / YG6X |
| K15 | Slightly improved toughness while maintaining good wear resistance | YG6X / YG8X |
| K20 | General-purpose grade with balanced wear resistance and toughness | YG8 |
| K30 | Better toughness and impact resistance | YG10 / YG10X |
| K40 | High toughness and high cobalt content, suitable for higher impact conditions | YG13 / YG15 |
