In the pharmaceutical industry, Powder Compression is a process in which the steel is in constant contact with the powder (Granulator, Mixer, Tablet Press with tooling). Therefore it requires custom-made compression tools made of a highly elaborate type of steel which must be altogether stainless, food-safe and conform to the FDA : 21CFR182 norm. The following types of steel AISI 302 - 303 - 304 - 316 – 410 - 416 - 440 comply with these demands. The AISI 440 steel is particularly well suited for powdercompression tools as it reaches a hardness of 56/58 HRC. This is the reason why we use the AISI 440 steel which offers a wide range of advantages :
Increased wear resistance
Washable in washing machines
Better sliding on the racks and compression rollers
Possible re-polishing of the punches
Increased lifetime
Non-sticky properties
