D2, D3, D6, and O1 hex bars are widely used in industries requiring high precision, durability, and wear resistance. These hex bars are made from premium-grade tool steels that offer excellent hardness and tensile strength. D2 hex bars are known for their high carbon content, making them ideal for cutting tools and dies. D3 hex bars provide exceptional wear resistance, suitable for applications in heavy-duty machinery. D6 hex bars are engineered for impact toughness and dimensional stability. O1 hex bars, as oil-hardening tool steel, are easy to machine and polish. Their uniform structure ensures consistent performance across various industrial applications.

The chemical composition of these hex bars ensures long-term reliability in demanding environments. D2 bars contain high chromium, providing corrosion resistance along with hardness. D3 bars feature increased carbon and vanadium levels for superior wear resistance. D6 hex bars are balanced with carbon and chromium to combine toughness and hardness. O1 hex bars have moderate carbon content, making them suitable for precise tooling applications. These steels can be heat-treated to achieve the required hardness levels. Heat treatment processes improve their cutting and forming capabilities. The selection of the appropriate hex bar depends on the specific operational demands.

Mechanical properties of D2, D3, D6, and O1 hex bars are essential for performance in tooling and industrial uses. D2 hex bars offer hardness up to 60 HRC with excellent wear resistance. D3 hex bars are extremely hard, with minimal deformation under high stress. D6 bars provide a combination of high hardness and impact strength, suitable for shock applications. O1 hex bars are versatile, with hardness typically around 55 HRC after oil hardening. These properties make them ideal for cutting tools, dies, punches, and other precision components. The consistent mechanical properties ensure durability in repeated cycles. Proper machining and finishing techniques enhance their functional lifespan.
