outstanding feature
Its outstanding characteristics are high hardness, wear resistance and thermal hardness (also known as red hardness). When the tool temperature is as high as 500~600℃, the hardness still does not decrease obviously, and it can cut at a higher speed than low alloy tool steel. It is mainly used to manufacture various cutting tools with high cutting speed, heavy load and high working temperature, such as turning tools, milling cutters, hobs, planers, broaches, drills and drills.

Features of df6 high-speed steel: The representative steel of W-Mo general-purpose high-speed steel has high toughness, good thermoplasticity, high hardness, red hardness and high temperature hardness.
DF6Co Cobalt-containing Wear-resistant High Speed Steel
Chemical composition (typical analysis result%)
Features:
● DF6Co is a high-speed steel containing cobalt, which has higher wear resistance, better red hardness and still high toughness. It was introduced by Yishengte on the basis of DF6(M2).
The high wear resistance of DF6Co mainly comes from moderate carbon saturation. (controlled between M2C), the hardness of DF6Co is improved to be more wear-resistant, while maintaining the high toughness of M2 steel.
Adding appropriate amount of cobalt, DF6Co obtained better red hardness. The addition of cobalt has the stability of ribbed use state.
● Use:
End milling cutter, saw blade milling cutter, superhard turning tool, machine tap, cutting circular saw blade and other tools. Machining stainless steel and titanium alloy has higher cutting efficiency than M2.
