Hobaneng ho nkela sebaka sa Stellite 21 e se "Fetola 'me U tsamaee"
Stellite 21 ke motsoako oa cobalt-chromium-tungsten o thatafalitsoeng ke eutectic carbides-M.7C3 le M23C6- e fana ka khanyetso e feteletseng ea ho koaleha, abrasion, le oxidation e phahameng ea mocheso. Empa ts'ebetso ea eona e ipapisitse le mefuta e mene e ke keng ea buisanoa: sekhahla sa ho tiisa nakong ea ho lahlela, potoloho ea kalafo ea mocheso ka mor'a weld, ts'ebetso ea carbide ho pholletsa le bokaholimo ba ho roala, le khokahano ea metallurgical ka har'a litlhophiso tse koaheletsoeng.
Liphatlalatsong tsa 'nete tsa lefats'e, re tloaetse ho lekanya boima ba li-gradients tse fetang 120 HV ka bophara ba 0.5 mm ka lisebelisoa tse sa sebetsoang hantle. Ke ka lebaka leo 73% ea mefokolo ea pele ho nako eo re e fumanang e khutlela ho sesosa se le seng: karolo e ile ea etsoa ho tloha sepacheng se entsoeng ho e-na le li-castings tse tiileng.
