In the realm of CNC machining and tool manufacturing, 6CrW2Si stands out as a high-carbon alloy tool steel engineered for high-impact, wear-resistant applications.

Compliant with GB/T 1299-2000 standards, this steel blends carbon (0.55–0.65%), chromium, tungsten and silicon to deliver exceptional hardness (≥57 HRC after quenching) and thermal stability. It retains 43–45 HRC even at 650°C, outperforming conventional tool steels in high-temperature stamping and cold-heading tasks.

6CrW2Si excels in making air hammer tools, cold shear blades and cold heading punches—critical components for forging flanges and high-strength fasteners. Its balanced toughness mitigates carbide segregation risks, ensuring long tool life and reduced downtime for machining workshops.

For businesses targeting European and Asian markets, this cost-effective steel offers reliable performance, making it a go-to choice for heavy-duty tooling solutions.
