GB/T 6Cr6W3MoVSi High Speed Tool Steel

The utility of 6Cr6W3MoVSi:
1. High Hardness and Wear Resistance
Applications: The addition of tungsten (W) and vanadium (V) gives 6Cr6W3MoSiV excellent hardness and wear resistance. This makes it ideal for manufacturing cutting tools like drills, taps, and milling cutters that require high durability and the ability to retain sharpness under heavy use.
2. Good Red Hardness
Applications: Red hardness refers to the steel's ability to maintain its hardness at elevated temperatures. The presence of tungsten, molybdenum (Mo), and silicon (Si) enhances this property, making 6Cr6W3MoSiV suitable for high-speed machining applications where the tools are subjected to high temperatures, such as in high-speed cutting tools and end mills.
3. Toughness and Resistance to Chipping
Applications: Despite its hardness, 6Cr6W3MoSiV maintains good toughness, which reduces the risk of chipping and breakage. This is important in tools like reamers and broaches, which must withstand significant mechanical stress during operation.
4. High Compressive Strength
Applications: The steel’s high compressive strength makes it suitable for applications that involve high pressures and loads, such as in cold-forming tools, dies, and punches.
5. Resistance to Thermal Fatigue
Applications: Thermal fatigue resistance is crucial in tools that undergo repeated heating and cooling cycles. 6Cr6W3MoSiV is used in such applications, including extrusion dies and hot forging tools, where the material must endure these cycles without cracking or deforming.
6. Versatility in Machining
Applications: The alloying elements in 6Cr6W3MoSiV make it versatile for various machining processes. It can be used for cutting both hard and soft materials, which makes it a popular choice in industries such as automotive, aerospace, and heavy machinery manufacturing.
7. Tool Life Extension
Applications: The combination of wear resistance, hardness, and toughness significantly extends the life of tools made from 6Cr6W3MoSiV, leading to reduced downtime and lower overall costs in production environments.
