ʻO ka ʻokoʻa ma waena o ke kila kalapona kiʻekiʻe a me ke kila kalapona haʻahaʻa

ʻO ke kila kalapona kiʻekiʻe ka mea i kapa pinepine ʻia he kila mea hana, me ka ʻike kalapona mai ka 0.6% a i ka 1.7%.ʻO nā mea maikaʻi: hiki ke loaʻa ka paʻakikī kiʻekiʻe a me ke kūpaʻa maikaʻi ma hope o ka mālama wela;ʻo ka paʻakikī paʻakikī i ke kūlana annealed a me ka machinability maikaʻi;loaʻa nā mea maka a haʻahaʻa nā kumukūʻai hana.ʻO nā mea pōʻino: ʻo ka paʻakikī wela maikaʻi ʻole, ke ʻoi aku ka nui o ka mahana hana o ka mea hana ma mua o 200 degere Celsius, ʻoi aku ka paʻakikī a me ka paʻa ʻana o ke kūpaʻa;haʻahaʻa ka paʻakikī.

ʻO ke kila kalapona haʻahaʻa he kila kalapona me kahi maʻi kalapona ma lalo o 0.25%.Ma muli o kona ikaika haʻahaʻa, haʻahaʻa paʻakikī a palupalu, ua kapa ʻia ʻo ia he kila māmā.Me ka nui o ke kila kalapona maʻamau a me kekahi kiʻekiʻe kiʻekiʻe kalapona structural kila, ka annealed hale o carbon kila he ferrite a me ka uuku nui o ka pearlite, he haʻahaʻa ikaika a me ka paakiki, maikai plasticity a me ka paʻakikī, a me ka weldability maikaʻi.
