He aha nā ʻano kila kila?

ʻOi aku ka kiʻekiʻe o ke kalapona o ke kila kila mea hana, ma waena o 0.65-1.35%. Ma hope o ka mālama ʻana i ka wela, hiki i ka ʻili o ke kila kila mea hana ke loaʻa ka paʻakikī a me ka paʻakikī kiʻekiʻe, a ʻoi aku ka maikaʻi o ke kaʻina hana o ke kumu; haʻahaʻa ka paʻakikī annealing (ʻaʻole ʻoi aku ma mua o HB207), maikaʻi ka hana hana, akā ʻaʻole maikaʻi ka paʻakikī ʻulaʻula. Ke hiki ka mahana hana i 250 ℃, hāʻule koke ka paʻakikī a me ke kūpaʻa o ke kila, a hāʻule ka paʻakikī ma lalo o HRC60. He haʻahaʻa ka paʻakikī o ke kila kila mea hana, a ʻaʻole hiki ke hoʻopaʻakikī ʻia nā mea hana nui (ʻo ke anawaena o ka paʻakikī i ka wai he 15mm). He ʻokoʻa loa ka paʻakikī o ka papa paʻakikī o ka ʻili a me ka ʻāpana waena i ka wā e kinai ai i ka wai, kahi maʻalahi ke hoʻololi a hana paha i nā māwae i ka wā e kinai ai. Eia kekahi, he haiki kona pae mahana quenching, a pono e hoʻomalu pono ʻia ka mahana i ka wā e kinai ai. Pale i ka wela nui, decarburization a me ka deformation. Hoʻokomo mua ʻia ke kila kila kila me "T" e pale aku i ka huikau me nā kila ʻē aʻe: ʻo ka helu ma ka helu kila e hōʻike ana i ka ʻike kalapona, i hōʻike ʻia ma nā tausani o ka awelika o ka ʻike kalapona. No ka laʻana, hōʻike ʻo T8 i ka awelika o ka nui o ke kalapona he 0.8%; no ka poʻe me ka nui o ka manganese, ua hōʻailona ʻia ʻo "Mn'" ma ka hopena o ka helu kila, no ka laʻana, "T8Mn'"; ʻoi aku ka haʻahaʻa o ka nui o ka phosphorus a me ka sulfur o ke kila kila kalapona kiʻekiʻe ma mua o ke kila kila kalapona kiʻekiʻe maʻamau, a ua hoʻohui ʻia ka leka A ma hope o ka helu kila e hoʻokaʻawale iā ia.
