The abbreviation PM in HSS-PM does not refer to the alloying constituents of the high speed steel, but to the method of manufacture. The liquid steel melt is atomized by means of nitrogen. The powder is then hot isostatically pressed (so-called HIP process) and then brought into the respective shape by forging and rolling as in conventional steel production. The advantages of steel result from the more uniform and finer carbide distribution (carbide = hard materials in steel). This makes the material easier to machine. In application, however, it is still wear-resistant and has a high hot hardness.
Titanium Carbo-Nitride (TiCN) has the highest lubricitiy of all the TiN coatings - making it an excellent choice as a dry film lubricant where improved hardness and wear resistance beyond standard Calico TiN is needed. TiCN is normally applied to steels, hardened steel, and stainless steel materials. TiCN is an excellent coating when working against bronze, brass and plastic, therefore, it a good choice for stamping, punching, and forming. Can be stripped and recoated.
