Cov kev kawm ua haujlwm tsis zoo: Tsis siv neeg plhaub tsis siv neeg plhaw cov khoom, tsis cia siab rau kev siv vuam siv tshuab, los tsim ib yam khoom tsim nyog uas muaj kev zoo siab, tshwj xeeb tsis siv vuam siv tshuab los tiv thaiv cov txheej txheem chromium ntau tshaj 28%, qhov nyuaj ntawm 58-62HRC, lees paub tias peb muaj cov txheej txheem tiv thaiv kab mob uas tsis muaj zog tiv thaiv kab mob. Cov kev sib tw coj ntawm metallurgy, xis mas thiab lwm yam kev lag luam proves tias wearability ntawm tus txhav resistant txheej ntau tshaj 30 zaus qhov sib npaug thickness ntawm 16Mn phaj.
