Nānā o nā pā kila Carbon
Hana ʻia nā pā kila kalapona mai loko mai o ka hao i loko o ka hao a me ka carbon. Hiki i nā kila kila ke komo i nā mea like ʻole me ka chromium, nickel, a me ka vanadium. Wahi a ka American Iron and Steel Institute, hiki ke wehewehe ʻia ke kila he kila kalapona inā ʻaʻohe mea liʻiliʻi i kuhikuhi ʻia a koi ʻia paha no ka chromium, cobalt, columbium, molybdenum, nickel, titanium, tungsten, vanadium, zirconium, a i ʻole kekahi mea e pono ai. hoʻohana ʻia e hoʻokō i kahi hopena alloying. He poʻe akamai mākou i ka hoʻolako ʻana i ka pā kila kalapona a he alakaʻi i ka mea kūʻai aku i ka pā kila kalapona, a me nā mea hoʻolako alakaʻi o ka ʻili kalapona.
Nā Pākēneka liʻiliʻi
No nā mea hoʻokahi, aia ka hapa haʻahaʻa i pono ʻole e hoʻonui ʻia:
● ʻAʻole pono ke keleawe ma mua o 0.40 pakeneka
● ʻAʻole pono ka manganese ma mua o 1.65 pakeneka
● ʻAʻole pono ka silikoni ma mua o 0.60 pakeneka
Loaʻa i nā pā kila kalapona a hiki i ka 2% o kā lākou mau mea hoʻohui hui a hiki ke hoʻokaʻawale ʻia i nā kila kalapona haʻahaʻa, nā kila kalapona waena, nā kila kalapona kiʻekiʻe, a me nā kila kalapona ultrahigh.
Na kila kalapona haahaa
Loaʻa i nā kila kalapona haʻahaʻa a hiki i ka 0.30 pakeneka kalapona. ʻO ka māhele nui loa no ke kila kalapona haʻahaʻa e pili ana i nā ʻāpana kila kalapona, nā huahana palahalaha. Hoʻohana maʻamau ʻia kēia i nā ʻāpana kino kaʻa, nā moena kaʻa, nā papa tin, a me nā huahana uea.
Na hao kalapona waena
ʻO nā kila kalapona liʻiliʻi (he kila māmā) loaʻa nā pae kalapona mai 0.30 a 0.60 pakeneka. Hoʻohana nui ʻia nā pā kila i nā mea hana, axles, shafts, a me ka forging. ʻO nā kila kalapona liʻiliʻi he 0.40 pākēneka a hiki i ka 0.60 pākēneka kalapona i hoʻohana ʻia ma ke ʻano he mea hana no ke kaʻaahi.
Na hao kalapona kiʻekiʻe
Loaʻa i nā kila kalapona kiʻekiʻe ka 0.60 a 1.00 pakeneka kalapona. Hiki ke hoʻohana ʻia ka hoʻohana ʻana i nā ʻāpana kila kalapona no nā mea hana e like me ka wili ikaika, ka punawai, a me ka ʻoki ʻana.
Na hao kalapona kiʻekiʻe kiʻekiʻe
ʻO nā kila kalapona Ultrahigh he mau ʻāpana hoʻokolohua i loaʻa ka 1.25 a 2.0 pakeneka kalapona. ʻIke pinepine ʻia ka hoʻohana ʻia ʻana o nā ʻāpana kila kalapona i nā pahi a me ka ʻoihana kūkulu hale.
