Aug 7, 2024 · Adhesive wear resistance: Prevents material transfer between the tool and workpiece, reducing built-up edge formation. Chemical wear resistance: Important when machining reactive materials or using certain cutting fluids. Thermal Stability. High temperatures generated during machining necessitate excellent thermal stability in cutting tool ...
- High Carbon Steel : Carbon content in this steel is 0.9% to 1.2% which makes the cutting edge of the tool very sharp. It loses its hardness at about 200°C temperature, which means its red hardness value is less.
- High Speed Steel : High-speed steel was invented by Tailer, who was an engineer. The H.S.S. 18 : 4 : 1 used nowadays is his invention. This steel contains 18% tungsten, 4% chromium, and 1% vanadium.
- Stellite: Stellite is a non-ferrous alloy containing 12 to 19% tungsten, 38 to 40% cobalt, 30 to 35% chromium, therefore having a red hardness value of 800°C.
- Cemented Carbide : The cemented carbide is a cutting tool having specific cutting characteristics. It is made by sintering of the tungsten carbide grains embedded in tougher metal.
Aug 8, 2023 · Ever wondered why certain tools outlast others? The secret lies in the steel used for tool making. This article explores various steel types, like 440C and VG10, highlighting their properties and best applications. Readers will gain insight into choosing the right steel to enhance tool performance and longevity.
Oct 12, 2018 · O-1 is an oil-hardening steel with high hardness and good machinability. This grade of tool steel is mainly used for items like cutting tools and drills, as well as knives and forks. A-2 is an air-hardening steel containing a medium amount of alloying material (chromium). It has good machinability along with a balance of wear resistance and ...
