Gumbara kw’isi {{0}=icuma, chromium hejuru n’ibindi vyambaye icuma kimwe- y’ivyuma vy’ivyuma, uburemere bw’icuma bugira ico bukoze ku bijanye n’ubushobozi bwo gusudira, kugira ngo umuntu ashobore gukoresha mu buryo busanzwe no gushiramwo bishobora kugabanya uburemere, kugira ngo uburemere bwaco bushobora kuba buri munsi ya HRC 40, yamara, ubushobozi bwayo bwo gusudira ntibushobora gusaduka mu nzira yo gusudira. Kugira ngo umuntu aronke uburinganire hagati y’ubushobozi bwo kwambara bwinshi, ubushobozi bwo gusudira n’ubushobozi bwo guhangana n’ingaruka, KMTBCr28 yambaye immumetal artive -iriho yaje mu kubaho kandi yarakoreshejwe cane kuva mu mpera z’imyaka ya 1990. KMTBCr28 igihimba c’umubiri c’umubiri (bimetallic) ntigishobora gusa gutuma habaho ugukomera kw’imiyoboro, ubushobozi bwo gusudira n’inkomezi (ubushobozi bwo guhangana n’ibintu), ariko kandi kugira ngo umuntu ashobore guhangana n’ibintu bihagije, ni uburyo bwiza cane bwo kuyambara - umuti udashobora kuwukoresha.
