ʻO 4145H kahi kila kila i hoʻohana nui ʻia no ka hana ʻana a me ka hoʻohana ʻana i nā mea hana ʻaila punawai. Hoʻopili ʻia ke kila i loko o ka umu ahi a hana ʻia ma o ka ʻenehana hoʻomaʻemaʻe palupalu. Eia kekahi, hoʻohana pinepine ʻia nā ʻaila hinu e hoʻomaikaʻi i ka hana o nā pahu drill. I ka hoʻohana ʻana i ke kila 4145H i nā pūnāwai kuhikuhi, hiki ke hoʻoheheʻe i ka torque haʻahaʻa a me ka wikiwiki kiʻekiʻe, a laila e hōʻemi i ka ʻaʻahu a me ka pōʻino i nā pou wili.
Ma muli o nā waiwai kila liʻiliʻi o ke kila 4145H a me ka wahi liʻiliʻi liʻiliʻi me ka lua wili, paʻakikī ke hana i kahi kāleka ʻokoʻa kaomi. ʻO kēia hiʻohiʻona e ʻoi aku ka hilinaʻi o ke kila 4145H i nā hana wili, ʻoiai e hōʻemi ana i ka friction me ka luawai a me nā poho pono ʻole.
ʻO ka hui kemika o 4145H kila ke kī i kāna hana maikaʻi loa. Hiki i ka lakio kūpono o ka hui kemika ke hōʻoia i ka hana paʻa o ke kila ma nā wahi paʻakikī e like me ke kiʻekiʻe kiʻekiʻe a me ke kaomi kiʻekiʻe. ʻO ka mea maʻamau, ʻo ka hui kemika o 4145H kila nā mea e like me carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), chromium (Cr), a me nickel (Ni). Hiki ke hoʻololi ʻia ka ʻike a me ka ratio o kēia mau mea e like me nā pono kikoʻī e hoʻokō i nā koi o nā hiʻohiʻona noiʻi like ʻole.
Ma ke ʻano he kila kila ikaika kiʻekiʻe, hoʻohana nui ʻia ia i ka hana ʻana i nā forgings a loaʻa iā ia nā pono penei:
Ka ikaika kiʻekiʻe: 4145H ka ikaika kiʻekiʻe a me ka ikaika tensile, e ʻae ana i nā forgings e pale i nā ukana a me nā koʻikoʻi. He koho kūpono kēia no nā noi e koi ana i nā mea ikaika kiʻekiʻe. Kūleʻa maikaʻi: Ma muli o ka hoʻohui ʻana o nā mea hoʻohui, 4145H maikaʻi ke pale ʻana i ka lole a hiki ke pale aku i nā hopena o ka lole, nā ʻāpana abrasive, a me ka friction. ʻO kēia ka mea i kūpono loa i ka forgings i hoʻohana ʻia i ka friction kiʻekiʻe a me ka ʻaʻahu ʻana i nā wahi. ʻO ka paʻakikī maikaʻi: 4145H ka hopena maikaʻi loa a hiki ke mālama i ka hana paʻa a me ka hana ma lalo o ka hopena a i ʻole ka haʻalulu. ʻO kēia ka mea e hiki ai i nā forgings ke hana ma lalo o nā kūlana paʻakikī a he palekana kiʻekiʻe. E maʻalahi ka hana: ʻOiai ʻo 4145H he kila kila kiʻekiʻe, ʻoi aku ka maikaʻi o ka hana ʻana. Hiki ke hana a hana ʻia ma o nā kaʻina hana e like me ka forging, ka mālama ʻana i ka wela, a me ka hana mīkini e hoʻokō i nā koi o nā ʻano like ʻole a me nā nui. ʻO ke kūpaʻa ʻino: 4145H maikaʻi loa ka pale ʻana i ka corrosion, ʻoi aku ka nui o ka wela a me ka haʻahaʻa. ʻO kēia ka mea e hiki ai i nā forgings ke hoʻomau i ke kūpaʻa i nā wahi kemika paʻakikī a hoʻonui i ko lākou ola lawelawe.
I ka hōʻuluʻulu ʻana, ʻo ka hoʻohana ʻana i ke kila 4145H i nā mea hana ʻaila punawai he mea nui. ʻO kāna hana ʻana i ka umu ahi arc a me ka ʻenehana hoʻomaʻemaʻe palupalu e hāʻawi iā ia me nā waiwai mechanical maikaʻi a me ka lōʻihi. ʻO ka lakio kūpono o kāna haku mele e hōʻoia i ka hana paʻa ma lalo o nā kūlana hana paʻakikī. Ma o ka noiʻi hou ʻana a me ka noiʻi hou ʻana, hiki iā mākou ke manaʻo i ka 4145H kila e pāʻani i kahi ʻoi aku ka nui ma ka māla ʻaila ʻaila e hiki mai ana, e hoʻomaikaʻi ana i ka pono wili a me ka hōʻemi ʻana i nā kumukūʻai.
