ʻOi aku ka kiʻekiʻe o ka ikaika ma mua o 15 kila, ʻaʻole hiki ke kinai ʻia, ʻaʻohe huhū ʻino deformation plasticity kiʻekiʻe maʻamau no ka kulou ʻana o ka calender flanging a me ka hana hāmare, e like me ke kuʻi ʻana arc a me ke kuʻi ʻana i ka hana kuʻihao maikaʻi, ka kuʻi ʻana i ka wā liʻiliʻi ka mānoanoa, ʻano paʻa a i ʻole. ʻO ke ʻano o nā ʻāpana paʻakikī e ʻoki ʻia i ka ʻoki ʻana i ke ʻano o ka mīkini huki ʻana a i ʻole ke kūlana annealing maʻamau i hoʻohana maʻamau i ka hana ʻana i ka ikaika ʻaʻole nui a kiʻekiʻe. ʻoʻoleʻa
Aia ke kila i ke kila kalapona haʻahaʻa haʻahaʻa kiʻekiʻe, ke kila extrusion carburized paʻakikī, he haʻahaʻa haʻahaʻa ke kila, paʻakikī maikaʻi, plasticity a weldability, ikaika tensile o 355-500mpa, elongation rate o 24%
Hiki i ka Normalizing ke hoʻoikaika i ka spheroidization o ke kila, hoʻomaʻemaʻe i ka ferrite block proeutectoid nui, a hoʻomaikaʻi i ka hana ʻoki ʻana o nā blanks ma lalo o 160HBS
ʻO ke ala ʻenehana o kakilaʻO nā ʻāpana make ʻo ia: ʻo ka hoʻolei ʻana i ka hoʻoheheʻe ʻana make blank annealing machinery rough machining cold extrusion molding recrystallization annealing machinery fine machining carburizing quenching tempering grinding polishing hui.
