16MnCr5 kaho porotaka tira wera

Ko te rino 16MnCr5 he rino miihini whakapakeke mo nga waahanga e hiahia ana kia kaha te kaha o te 800 – 1100 N/mm² me te pai o te mau kakahu. He rauemi miihini e whakamahia ana hei hanga i nga raka piston, camshafts, reera me etahi atu waka me nga waahanga miihini miihini.
EN 1.7131 maitai (16MnCr5 rauemi) Ko te maitai carburized paerewa Pākehā (case hardening maitai) ki te hardenability pai me te machinability. Mo nga waahanga whitinga nui ake, ka taea te whiwhi i te pakeke o te mata me te whakakakahu i muri i te maimoatanga wera, me te kaha o te kaha o te pawera iti. Mo te whakatakotoranga me te papanga raraunga, tirohia nga ripanga kei raro nei.
Ko te maitai 16MnCr5 te nuinga o te whakamahi i muri i te carburizing me te tinei, a ka whakamahia te nuinga mo te hanga taputapu, kutukutu, hiri hiri me etahi atu waahanga.

Ko te ripanga e whai ake nei e whakaatu ana i te hanganga matū o te rauemi 16MnCr5 (1.7131 maitai).
