What are the materials for taps

1. Tool steel: commonly used for hand cutting taps, it is no longer common.

2. Cobalt free high-speed steel: currently widely used as tap material, such as M2 (W6Mo5Cr4V2, 6542), M3, etc., marked with the code HSS.

3. Cobalt containing high-speed steel: currently widely used as tap material, such as M35, M42, etc., with the marking code HSS-E.

4. Powder metallurgy high-speed steel: used as a high-performance tap material, its performance is greatly improved compared to the two, and the naming method of each manufacturer is also different, with the marking code HSS-E-PM.

5. Hard alloy materials: usually selected with ultra-fine particles and good toughness, mainly used for manufacturing short chip materials for straight groove tap processing, such as gray cast iron, high silicon aluminum, etc.

Taps are highly dependent on materials, and selecting good materials can further optimize the structural parameters of the tap, making it suitable for efficient and more demanding working conditions, while also having a higher lifespan.
