65Mn yotentha yozungulira zitsulo zozungulira

65Mn zitsulo ndi Chinese GB muyezo kasupe zitsulo kalasi, Manganese (Mn) bwino hardability, kotero mphamvu, kuuma, elasticity ndi hardability ndi apamwamba kuposa 65 # zitsulo, koma ali ndi kutenthedwa kutengeka ndi kupsa mtima brittleness. Kuzimitsa madzi kumapangitsa kuti ming'alu ikhale. The annealed state ali machinability zabwino, otsika ozizira deformation plasticity, ndi weldability osauka.
65Mn high carbon steel imagwiritsidwa ntchito makamaka popanga akasupe ang'onoang'ono ang'onoang'ono, akasupe ozungulira, mawotchi, ndi zina zotero. Ikhoza kugwiritsidwanso ntchito popanga mphete za kasupe, akasupe a valve, zowonongeka, mabango a clutch ndi akasupe ophulika.
