Whakaahuatanga Poto:
He pai ake te ahua o tenei ahua o te maitai i te 30Mn2 maitai, te pakeke teitei, te diameter hardenability nui o te 8 ~ 22mm i roto i te wai, te pai machinability, te reo makariri deformation plasticity me te weldability;I tua atu, ko te pakari o te rino e kore e tino heke i te wa o te maimoatanga wera, engari he tino kaha te kaha me te mau atete, ina koa ka tinei te wai;Heoi, ko tenei rino he ngawari ki nga waahi ma, te ngawari o te riri me te wera nui i te wa o te maimoatanga wera.
