He aha nā ʻano kila mea hana ma laila?

He kiʻekiʻe ke kiʻekiʻe o ke kalapona kalapona kila, ma waena o 0.65-1.35%. Ma hope o ka hoʻomaʻamaʻa ʻana i ka wela, hiki i ka ʻili o ke kila kila kila ke kiʻekiʻe aʻe ka paʻakikī a me ka paʻakikī, a ʻoi aku ka maikaʻi o ke kaʻina hana; he haʻahaʻa ka paʻakikī annealing (ʻaʻole iʻoi aku ma mua o HB207), maikaʻi ka hana hana, akā ʻilihune ka ʻulaʻula. Ke piʻi ka mahana hana i 250 ℃, hāʻule 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, a ʻaʻole hiki ke paʻakikī i nā mea hana nui (ʻo 15mm ke anawaena o ka paʻakikī i ka wai). ʻOkoʻa loa ka paʻakikī o ka ʻili a me ka ʻaoʻao waena i ka wā e hoʻopau ai i ka wai, maʻalahi ke hoʻololi a hana ʻia paha nā māwae i ka wā e hoʻopau ai. Eia kekahi, he haiki kona pae wela, a pono e hoomalu pono ia ka wela i ka manawa o ke kinai ana. Kāohi i ka overheating, decarburization a me ka deformation. Hoʻopili mua ʻia ke kila kila kila me "T" i mea e pale ai 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 ka hapahā o ka maʻiʻo kalapona maʻamau. No ka laʻana, hōʻike ʻo T8 i kahi maʻi kalapona awelika o 0.8%; no ka po'e me ka nui o ka manganese, ua kaha 'ia ka "Mn'" ma ka hope o ka helu kila, no ka la'ana, "T8Mn'"; ʻoi aku ka haʻahaʻa o ka phosphorus a me ka sulfur o ke kila kila kila kiʻekiʻe ma mua o ke kila kila kila kiʻekiʻe, a hoʻohui ʻia ka leka A ma hope o ka helu kila e ʻike ai.
