It is machinable & is available in few sizes only. Suitable for fast, high wear & chipping machinability, works with high graded steel aluminum, carbon contained alloys etc. Turning and milling tools for roughing and finishing work, wood working tools, highly stressed cold work tools, tool bits.
Introduction of PM STEEL
With new technologies & innovations coming our way, high categorized High speed steel with Powder used technology has been introduced as Powder Metallurgy (P.M.).
With high demands from around the world, Powder made steel has started replacing earlier made HSS. It has become a wide popular choice for various diverse applications for tooling in mechanical as well as CNC. It is perfect for an ample variety of users that grind, not except operations with alloys of the high temperature and exotics.
With life of the tools as almost equal to twice, PM steel has given the best performance in comparison to even carbide, leave the earlier used HSS. Due to high chemical composition of Cobalt, Vanadium, Tungsten, Nickel the steel grains stick to its properties stronger with offering us the best steel to be used for high performance tools. High speed steel produced by the powder metallurgy method for heavy duty machining tools e.g. for machining of nonferrous metals alloys, such as Ti-base & Ai-alloys. Tools exposed to high compressive stresses, e.g. in fine blanking tools for high-strength materials.
