65Mn zafi birgima karfe zagaye sanduna

65Mn karfe ne na kasar Sin GB misali spring karfe grade, Manganese (Mn) inganta taurin, don haka ƙarfi, taurin, elasticity da taurin sun fi na 65 # karfe, amma yana da zafi ji na ƙwarai da kuma m gaggautsa. quenching ruwa yana ƙoƙarin haifar da fasa. Jihar da aka rufe tana da ingantattun injina, ƙarancin nakasar sanyi mai sanyi, da ƙarancin walda.
65Mn high carbon karfe ne yafi amfani a yi na daban-daban kananan-section lebur marẽmari, zagaye marẽmari, clockwork, da dai sauransu Har ila yau, za a iya amfani da su ƙera spring zobba, bawul marẽmari, shock absorbers, kama reeds da birki marẽmari.
