Composition Differences

 

Tungsten Steel:
Tungsten steel mainly consists of tungsten carbide (WC) and cobalt (Co). Tungsten carbide is the hard phase, endowing the material with high hardness and wear - resistance. Cobalt is the binder phase, and its function is to bind tungsten carbide particles together, giving the material a certain degree of toughness and strength. Generally speaking, the content of tungsten carbide is relatively high, ranging from 80% - 97%, and the cobalt content is around 3% - 20%. According to different application requirements, a small amount of elements such as titanium (Ti) and tantalum (Ta) may also be added to further improve the performance. For example, adding titanium can form TiC, refine the grain, and increase the hardness and wear - resistance.

 

High - Speed Steel:
High - speed steel is a kind of high - alloy steel. Besides containing a relatively high amount of tungsten (W, generally 9% - 18%), it also contains alloy elements such as chromium (Cr, about 3.8% - 4.4%), vanadium (V, about 1% - 2%), and molybdenum (Mo, about 0 - 5%). In high - speed steel, tungsten mainly forms carbides with carbon, such as WC and . These carbides can maintain relatively high hardness at high temperatures, thus endowing high - speed steel with good red - hardness. Chromium is mainly used to improve the hardenability and antioxidant property of the steel. Vanadium can form VC carbide with extremely high hardness, refine the grain, and molybdenum can partially replace the role of tungsten and improve the performance of the steel.

Performance Characteristics

 

Hardness and Wear - Resistance:
Tungsten Steel: It has extremely high hardness, and its hardness generally ranges from HRA89 - 93 (Rockwell hardness A scale). It has excellent wear - resistance at room temperature. Due to the high hardness of the tungsten carbide hard phase, when processing materials with high hardness (such as hardened steel, cemented carbide, etc.), tungsten - steel cutting tools can maintain a good cutting - edge shape and reduce tool wear. For example, in the stone - carving industry, tungsten - steel cutting tools can precisely carve hard stones and remain sharp for a long time.
High - Speed Steel: The hardness generally ranges from HRC62 - 67 (Rockwell hardness C scale). Although its hardness is slightly lower than that of tungsten steel, it can still maintain relatively high hardness in a high - temperature environment. This is because the carbides formed by its alloy elements are stable at high temperatures, enabling high - speed steel to have good red - hardness. For example, during high - speed cutting processing, when the temperature of the cutting - edge of the high - speed - steel cutting tool rises, it will not soften as quickly as ordinary carbon - steel cutting tools and can still effectively cut metal materials. In terms of wear - resistance, high - speed steel also performs well to a certain extent, but its wear - resistance is not as good as that of tungsten steel.
