65Mn mau kaola poʻe kila ʻōwili wela

ʻO 65Mn kila he Kina GB punawai kila maʻamau, Manganese (Mn) hoʻomaikaʻi i ka hardenability, no laila, ʻoi aku ka ikaika, ka paʻakikī, ka elasticity a me ka paʻakikī ma mua o ka 65 # kila, akā he overheat sensitivity a me ka huhū brittleness. ʻO ka hoʻopau ʻana i ka wai e hana i nā māwae. Ka annealed moku'āina i maikai machinability, haʻahaʻa anu deformation plasticity, a ilihune weldability.
65Mn kiʻekiʻe kalapona kila ua nui hoʻohana 'ia i loko o ka hana 'ana i nāʻano liʻiliʻi-ʻāpana palahalaha punawai, poepoe puna, clockwork, etc. Hiki ke hoʻohana 'ia no ka hana ana i nā apo apo, valve punawai, haʻalulu, clutch ohe a me ka uhaki puna.
