Alongside with the specified materials firm " Stommat " makes and, stainless steels of type traditionally used in stomatology 25H18N9C2 . In 1996 specifications Gudermesskogo of a factory on delivery by last are transferred to firm " Stommat " by the decision of Ministry of Health and the Medical Industry of the Russian Federation.
Steel stomatologic 3CKC-01 is issued as measured passport preparation and is intended for manufacturing cast artificial limbs with a covering nitride of the titan. Steel 3CKC-01 is analogue of widely known steel in stomatology 25H18N9C2. Alloys is a cast material produced by alloying of commercially pure metals in vacuum induction furnaces. The alloy is characterized with required level of technological, physical and chemical and mechanical properties in accordance with requirements of the international standards. It has high corrosion resistance and meets to toxicology and sanitary requirements for stomatology materials.
Heightened fluidity of the alloys makes it possible to cast thin-walled parts having thickness up to 0.3 mm. The products made from this alloy are well workable by abrasive tools and polishing means. Alloys properties ensure a reasonably high strength of metal-ceramic bonds on application of porcelain masses, i.e. it may be used for metal-ceramic dentures producing.
