Kutentha kwakukulu kwa chitsulo cha carburized kumabwera chifukwa cha mpweya wambiri wosanjikiza. Chitsulo cha kaboni w (C) chikakhala chochepera pa 0.43%, gawo lomwe limadzaza ndi mafuta limakhala ndi mwayi wotsutsana, ndipo w (C) Ikakhala yayikulu kuposa 0.45%, kulimbikira kwa magawo olimba kumathandizira. Izi ndizomaliza zomwe TH HACAHOBA ajambula potengera kuyesa kwa pini. Chifukwa chake, pini ya thalakitala imalowetsedwa ndi njira yatsopano yolimbitsira zitsulo 50. . Kufanizira kwa kukana kwamitundu yosiyanasiyana ya w (C) utatha kutsekedwa kwazithunzi kumawonetsera kukopa kwazitsulo. Zomwe zili patebulo zikutsimikizira kuti chitsulo cha T7 chimakhala ndi chovala chochepa kwambiri, ndipo zomwe zili ndi kaboni komanso kuuma kwake ndizopamwamba kwambiri; Zitsulo 45 ndi 50Mn zimakhala ndi kukana kofanana; Chitsulo cha 45Cr chimakhala ndi kukana pakati pa T7 chitsulo ndi 50Mn chitsulo, posonyeza kuti chitsulo chili ndi Ming chitha kukonza kukana kwa abrasion.
