Tungsten in steel

Tungsten is an important alloying element in steel, especially in high-speed tool steels.

Effect on properties: It forms very hard and stable carbides (tungsten carbides) that greatly enhance the wear resistance of the steel.

Cutting ability: Tungsten maintains hardness even at elevated temperatures (red hardness), which significantly improves the cutting ability of tools.

Toughness: Addition of tungsten also contributes to improved toughness of the steel, making it suitable for high-stress applications.

Conclusion: Therefore, tungsten in steel mainly improves wear resistance, cutting ability and toughness.
