Cobalt-based high-speed steel is a high-carbon high-alloy tool steel with cobalt as the main alloying element, which is commonly used as high-performance tools and cutting tools. Compared with conventional high-speed steel, cobalt-based high-speed steel has higher hardness and wear resistance, while also having better red hardness and toughness.
ASP23 is a commonly used cobalt-based high-speed steel whose chemical composition is mainly composed of elements such as tungsten, chromium, molybdenum, vanadium and cobalt. After proper heat treatment, the hardness of this steel can reach HRC64-66, and it has excellent wear and heat resistance, so it is widely used in cutting tools, stamping dies, milling cutters and other fields.
Compared with traditional carbon tool steels and high-speed steels, cobalt-based high-speed steels have higher hardness and wear resistance, while also having better resistance to hot cracks and adhesion. These properties make cobalt-based high-speed steel excellent when machining materials with high hardness, strength, and high wear resistance.
However, despite its many advantages, cobalt-based high-speed steel is more expensive to manufacture and may not be prioritized in some cost-sensitive occasions. In addition, due to the high hardness and wear resistance of cobalt-based high-speed steel, its cutting speed and feed must also be adjusted accordingly, otherwise it may negatively affect tool life and machining efficiency.
In general, ASP23, as a cobalt-based high-speed steel, has excellent hardness and wear resistance, as well as good red hardness and toughness. These properties make it a high-performance tool material for a wide range of machining applications.
