High Speed Steels are designed from high carbon tool steel that includes high dose of tungsten. They are developed using 18% tungsten, 0.7% carbon, 4% Chromium, 1% Vanadium, and Iron to ensure to create hard and durable cutting tools, power saw blades, drill bits and tool bits. In addition to this, they are available with cobalt up to 8% to impart maximum strength and wear resistance design. They are superior to the high-carbon steel as they can easily withstand higher temperatures without any effect on the durability and hardness.
Features of High Speed Steels:
1. Easy and fast to cut than high carbon steel
2. High hardness and abrasion resistance
3. Increases tool's hardness as well as lubricity
4. Excellent robustness at high hardness
