Product Description:
83WV3 is a high-carbon, chromium-vanadium tool steel primarily used for manufacturing cutting tools, dies, and other high-performance industrial tools. The alloy has a combination of carbon, chromium, and vanadium, which provides it with excellent hardness, wear resistance, and toughness. It is commonly employed in the production of tools that are exposed to heavy wear and high temperatures, such as punches, dies, and blades.
83WV3 steel is known for its ability to withstand high-impact stresses, making it ideal for manufacturing tools that need to maintain sharpness and precision under challenging working conditions. The alloy also has good hardenability and can be heat-treated to achieve superior strength and hardness, making it suitable for a range of industrial applications.
Features:
- High Hardness: After heat treatment, 83WV3 steel exhibits excellent hardness, which makes it highly resistant to wear and abrasion.
- Wear Resistance: The alloy's high carbon and vanadium content significantly increase its resistance to wear, making it ideal for use in cutting tools and dies.
- Good Toughness: 83WV3 offers good toughness, meaning it can withstand high-impact loading and resist brittle fracture.
- High Wear Resistance at Elevated Temperatures: The alloy can maintain its hardness and wear resistance even at elevated temperatures, making it suitable for hot-working applications.
- Hardenability: It has excellent hardenability, allowing it to achieve high hardness levels even when the thickness of the workpiece is substantial.
