Powder Metallurgy Steels (P.M. steel) and Powdered High Speed Tool Steels are an interesting group of steels that are often used in industrial applications that require tools capable of cutting steel and also withstanding tremendous forces and high temperatures. P.M. steels are made using a variety of proprietary methods, but the basic process usually involves atomizing molten steel by spraying it through a very fine nozzle and in to a container of liquid nitrogen. This produces microscopic droplets of steel with a very fine grain structure and excellent metallurgical properties. Once the resulting powdered steel has been cleaned and sorted, according to the size of the droplets, it is sintered in to an ingot using a hot isostatic press. This process involves heating the metal to just below its melting point and applying extremely high pressure in order to consolidate the steel and remove voids.
For users of kitchen knives, the main benefits of P.M. steels are typically considered to be:
Accordingly, we especially recommend knives made with Powder Metallurgy Steels to serious knife enthusiasts and culinary professionals who demand knives with the best possible edge retention and cutting performance.
