Introduction of PM STEEL
The Powder made steel formation process results in a homogeneous microstructure with a finer, more uniform carbide distribution imparting superior dimensional stability, grind ability and toughness when compared to steels produced by conventional processes. This process also allows the design of more highly alloyed grades which cannot be produced by conventional steelmaking
Powder Metallurgy formation of steel is highly costly since the process of annealing and forging via nitrogen technology is costly. Producing Various High speed steel grades via powder metallurgy formation process is completely different than already commonly used HSS conventional way via forging/annealing/hardening/ grinding route. With high demands from around the world
Nowadays, with huge demand of Powder HSS, Conventional HSS has started to get replaced by this Effective PM Steel. It has become a wide popular choice for various diverse applications for tooling in mechanical as well as in CNC. It is suitable 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, 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.
