> DF6Co(W6Mo5Cr4V2Co2)含鈷耐磨高速鋼DF6(M2\SKH51)/DF6M(SKH54)一勝特高速工具鋼化學(xué)成分力學(xué)性能
DF6Co(W6Mo5Cr4V2Co2)含鈷耐磨高速鋼DF6(M2\SKH51)/DF6M(SKH54)一勝特高速工具鋼化學(xué)成分力學(xué)性能
●???DF6Co是一勝特在DF6（M2）基礎(chǔ)上推出的耐磨性更高，紅硬性更好，仍保持高韌性的含鈷高速鋼。
●???DF6Co更高耐磨性主要源于適度的碳飽和度。（控制在M2C之間）,提高了DF6Co的使用硬度從而更耐磨，同時(shí)又保持了M2鋼的高韌性。
●???DF6Co通過適量鈷的加入獲取了更好的紅硬性。鈷的加入有肋使用狀態(tài)的穩(wěn)定和細(xì)晶體的保持，有效提升了鋼的回火穩(wěn)定性,同時(shí)保持高的韌性。
●???用途：
立銑刀、鋸片銑刀、超硬車刀、機(jī)用絲錐、切割圓鋸片等各類刀具。加工不銹鋼及鈦合金有比M2更高的切削效率。

End mill, Slitting saws, extra hard lathe bit, machine tap, circular saw blades, etc. When processing stainless steel and titanium alloy, DF6Co has better efficiency than M2

- Basing on DF6 (M2), EAST TOOL introduced cobaltic high speed steel DF6Co, which has stronger wearlessness, better red hardness, and keep high tenacity.
- Moderate saturation degree of carbon (keep between M2 and high carbon M2C), improve the workable hardness of DF6Co, and keep the high tenacity of M2 steel.
- After adding in a right amount of cobalt, DF6Co gets better red hardness. Adding cobalt contributes to stability of carbide and maintenance of fine grain in work, improves the tempering stability of steel and keeps in state of strong wearlessness.
