Litšepe tse chitja tse 65Mn tse chesang

65Mn steel ke Chinese GB standard spring steel grade, Manganese (Mn) e ntlafatsa ho thatafala, kahoo matla, thata, elasticity le hardability li phahame ho feta tsa 65 # tšepe, empa e na le kutloelo-bohloko e feteletseng le bohale ba brittleness. Ho tima metsi ho atisa ho etsa mapetsong. Naha e kentsoeng e na le machinability e ntle, polasetiki e tlase e batang ea deformation, 'me ha e chesehele hantle.
65Mn high carbon steel e sebelisoa haholo-holo ha ho etsoa likhaba tse fapa-fapaneng tse sephara, liliba tse pota-potileng, li-clockwork, joalo-joalo. E ka boela ea sebelisoa ho etsa mehele ea selemo, li-valve springs, shock absorbers, lehlaka la clutch le liliba tsa brake.
