Amoung the many factor that go into steel selection for the manufacturer of Punches & Dies for the tablet are tonnaged required, chemical atmosphere, abrasive nature of the product, turret speed; cup depth, location of embossing, bisect land and physical condition of press.

For general punches application oil hardened non-shrinking steel S grade are chosen because they combine high toughness and low to medium wear resistance. The Principal alloying elements in this steel are manganese, silicon and chromium, tungsten, moly & dennum in percentage wise. It is applicable to all pharmaceutical industries in normal application , We call it is JAYSHREE-S (Standard).

For high wear application D-2, D-3 high carbon high chromium steel is recommend . D-2 HCHCr steel are abrasive resistance, but don't have. The ductility or toughness of the S grade of steel. D-2 Punch are susceptible to cracking and caution must be exercised in application with embossed & deep cup Punches. D-3 steel is used for Dies only. These grades of steel are referring as premium steel for tools, we called it as a JAYSHREE-P (Premium).

For corrosive products SS 440 C Stainless steel is used for the Punches. This grade has low toughness rating and wears resistance falls between S&D series of steel. It is applicable to chemical industries where corrosion is main factor than wear resistance, we called it JAYSHREE-440 C.

Please note that no single tool material has combine maximum wear resistance, toughness and corrosion resistance. Consequently, the selection of proper steel for Punches & Dies may required an optimal combination of properties.
