ʻO kaʻikepili o ka Carbon a me ka paʻakikī o ka 440A-440b-440c i hoʻonuiʻia mai ABC (A-0.75%, C-1.2%, C-1.2%. ʻO ka 440c kahi kiʻekiʻe maikaʻi loa-hope loa i keʻano o ka paʻakikī me ka paʻakikī o 56-58 rc. ʻO kēia mau kilaʻekolu i loaʻa i ke kū'ēʻana, 440a ka mea maikaʻi loa, aʻo 440c ka haʻahaʻa loa. He maʻamau loa ka 440C. ʻO keʻano o ka cmoposition o ka cimenietic stienless stivless steel e like me ka mea like me ka huiʻana o ka molybden nui o 0.1%-0% -27% cr. Mai ka hoʻolālāʻana o keʻano o ka Tissue i kahiʻano cubic cubic cubic, ke kauʻana o ka ikaika ma nā kiʻekiʻe kiʻekiʻe. Ma lalo o 600 ° C,ʻO ka ikaika kiʻekiʻe kiʻekiʻe o ka laulā kiʻekiʻe,ʻo ia ka kiʻekiʻe o nā kila kila, aʻo ka ikaika hoʻi ka kiʻekiʻe. ʻO 440a he nui a me nā waiwai paʻakikī a paʻakikī hoʻi. Uaʻoi aku ka paʻakikī ma mua o 440b Steel a me 440c Steel. Hoʻohanaʻia 440B no nā mea hanaʻokiʻoki, ke anaʻana i nā mea hana, nā mea hana a me nā awāwa. He paʻakikīʻoi aku ka paʻakikī ma mua o 440a Steel a me ke kiʻekiʻe kiʻekiʻe ma mua o 440c Steel. Loaʻa iā 440C ka paʻakikī kiʻekiʻe loa o nā kila kila a me nā kila wela a me ka wela-resian a hoʻohanaʻia no nā nozzles a me nā mea mālama. ʻO 440F kahi helu kila e hoʻomaikaʻi i nā waiwai iʻokiʻia i nā waiwai o 440c no ka itala no nā laha.
