Cobaltic & Abrasion Resistant High Speed Steel, DF6Co

Zhejiang East Tool & Die Co or “East Tool” is one of the most prominent tool and die steel manufacturers of special steel in China. EST Tool Steel Pvt Ltd is an alliance of East Tool and Magicut, a prominent tool manufacturer of India. The company has introduced Cobaltic and Abrasion resistant High Speed Steel, DF6Co. Based on DF6 (M2), this has stronger wearlessness, better red hardness, and keep high tenacity. Moderate saturation degree of carbon (kept between M2 and high carbon M2C), improves the workable hardness of DF6Co, and keeps 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. Applications: end mills, slitting saws, extra hard lathe bits, machine taps, circular saw blades, etc. When processing stainless steel and titanium alloy, DF6Co has better efficiency than M2.
