Special steels
The main requirements for steels used in the manufacturing of compression tooling are the wear resistance, good resistance to chipping, high compressive strength, good through hardening properties, high hardness after high temperature tempering and good stability in hardening.
ASCORP. uses steel grades which fulfill those requirements and purchase them only from world leading steel producers.
Besides the standard steel grades used by all compression tooling suppliers, ASCORP. offers a series of different specialty steels which can solve the tableting problems with abrasive, sticky and corrosive products as well as products which requires the higher compression forces than recommended due to the tablet size and dimensions. Such steels with the combination of different coatings, the right surface finish and very narrow dimensional tolerances make the tooling supplied by ASCORP. one of the best in the world.
The following tabulation will give you a brief idea of the type of steel and its properties.
Symbols
C= Carbon
Cr= Chromium
Mn= Manganese
Mo= Molybdenum
Ni= Nickel
P= Phosphorous
S= Sulphur
Si= Silicon
Ti= Titanium
V= Vanadium
W= Tungsten
*Note : PM-2 and PK-3 are high premium steel manufactured with powder metallurgy technology and by electro-slag remelting (ESR) process. The ESR process gives a better control of the solidification of the microstructure and chemical homogeneity and thus betters the mechanical properties.
Steel Options: A2, D2, DC-53, D3, M2 PM-M4, S7, PM-3V, Tungsten Carbide, 440C and M340
