CPM T15 is a powder high-speed steel with the following main components and performance characteristics:
Chemical Composition: Tungsten (W): CPM T15 has a high content of tungsten, which is one of the key elements that provide high hardness. It significantly increases the hardness of the material, making it suitable for cutting and machining highly hardness materials.
Cobalt (CO): Components containing cobalt increase the redness and hardness of the material, i.e. maintaining hardness and machinability at high temperatures. This gives the CPM T15 excellent cutting performance at high temperatures.
Chromium (CR): The presence of chromium helps to improve the corrosion resistance and thermal stability of the material, making tools and molds more durable during use.
Vanadium (V): The addition of vanadium helps to increase hardness and wear resistance, making CPM T15 suitable for cutting and machining materials that require high wear resistance.
Performance characteristics: High hardness: CPM T15 has a very high hardness, usually between HRC 65-67, which makes it very suitable for cutting high hardness materials, such as high-speed steel, high-temperature alloys, etc.
Abrasion resistance: CPM T15 is about 5-7 times more abrasion resistant than conventional high speed steel, which means it can keep the tool sharp for longer in cutting and abrasive environments.
Red hardness: Contains cobalt components, with excellent red hardness, can maintain hardness and cutting performance under high temperature conditions, suitable for high temperature cutting applications.
Toughness: It is similar to the toughness of M2 high speed steel, which means that it is relatively durable during the cutting process and is not easy to break.
Corresponding grades in each country:
United States: CPM T15 is a powdered high-speed steel produced by the American Furnace Sber Company, usually referred to by the name CPM T15.
China: In China, similar types of steel may be trademarked and graded**. In general, CPM T15 can correspond to domestic high-speed steel grades, such as domestic W18Cr4V or W6Mo5Cr4V2.
It is important to note that different countries and manufacturers may use different names and grades to refer to similar materials, but their chemical composition and performance characteristics are often similar. When selecting a tool or mold material, it is best to base the selection on the specific application needs and the manufacturer's recommendations to ensure that the material meets the required performance requirements.
