Poyerekeza ndi mbale zachitsulo zachikhalidwe zosatha kutha, gawo logwira ntchito la mbale yotha kutha ya CCO lili ndi gawo lalikulu la zinthu za Cr ndi C (zomwe zili mu Cr 27-45%, zomwe zili mu C 3-5%), zomwe zimatha kupanga ma carbide olimba a M7C3 nthawi zonse akamagwira ntchito, okhala ndi kuuma kwa Mohs kwa 58-65HRC, zomwe zimathandizira kwambiri kukana kugwedezeka ndi kutha kutha.

Chogulitsachi chimathandizira kukonza malinga ndi zojambula, mawonekedwe apadera okonzedwa, malo otseguka okonzedweratu, kupindika ndi kuwotcherera, ndipo ndi choyenera pa nyumba zosiyanasiyana zovuta, monga:
