ʻO kahi alloy kaulana no kona ikaika ʻoi aku ka maikaʻi, ka pale ʻana i ka corrosion, a me ka nani, ua hoʻololi ke kila kila i nā ʻoihana lehulehu. Eia nō naʻe, ʻo ka hoʻokele ʻana i nā ʻano nui o nā māka kila kila hiki ke lilo i hana paʻakikī. Mai makaʻu, ʻoiai ke komo nei kēia alakaʻi piha i ka honua paʻakikī o ke kila kila, e hoʻolako iā ʻoe me ka ʻike e koho i ka papa kūpono no kāu mau pono kikoʻī.
Hoʻolauna iKila kohu ʻole: He mau mea paa loa
ʻO ke kila kila kahi huaʻōlelo umbrella e uhi ana i nā ʻano huila i ʻike ʻia no ko lākou hiki ke kūʻē i ka corrosion, kahi waiwai i hāʻawi ʻia i ka liʻiliʻi o 10.5% chromium. ʻO kēia ʻāpana pale, i ʻike ʻia he kiʻiʻoniʻoni passive, e hana maʻamau i ka wā e ʻike ʻia ai i ka oxygen, e pale ana i ke kila ma lalo mai nā hopena pōʻino o ke kaiapuni.
Ka hoomaopopo ana i kaKila kohu ʻole Pūnaehana Papa: Wehewehe i nā Helu
Ua hoʻomohala ka American Iron and Steel Institute (AISI) i kahi ʻōnaehana helu maʻamau e hoʻokaʻawale i nā māka kila kila. ʻIke ʻia kēlā me kēia papa e kahi helu ʻekolu-helu, me ka huahelu mua e hōʻike ana i ka moʻo (austenitic, ferritic, martensitic, duplex, a i ʻole precipitation hardenable), ʻo ka huahelu ʻelua e hōʻike ana i ka ʻike nickel, a ʻo ka huahelu ʻekolu e hōʻike ana i nā mea hou a i ʻole nā hoʻololi.
I loko o ke ao o ke kila kila: wehe i ka ʻelima nui
ʻO Austenitic Stainless Steels: ʻO nā All-Rounders
ʻO nā kila kila Austenitic, i hōʻike ʻia e ka 300 series, ʻo ia nā ʻano maʻalahi a hoʻohana nui ʻia. Hōʻike ʻia e ka ʻikepili nickel kiʻekiʻe, hāʻawi lākou i ka formability maikaʻi loa, weldability, a me ka pale ʻana i ka corrosion, e hoʻolilo iā lākou i mea kūpono no ka hoʻoili ʻana i ka meaʻai, kemika, a me nā noi olakino. ʻO nā māka i hoʻohana maʻamau ʻia ʻo 304 (ke kumu nui), 316 (ka papa moana), a me 310 (ke wela kiʻekiʻe).
ʻO Ferritic Stainless Steels: The Iron Champions
ʻO nā kila kila Ferritic, i hōʻike ʻia e ka 400 series, ua ʻike ʻia no ko lākou mau waiwai magnetic, ikaika kiʻekiʻe, a me ke kumukūʻai. Eia nō naʻe, he haʻahaʻa ko lākou maʻiʻo nickel ma mua o nā kila stainless austenitic, e hoʻemi ʻole iā lākou i ka corrosion. Loaʻa nā noi maʻamau i nā ʻāpana kaʻa, nā mea hana, a me nā mea kūkulu hale. ʻO nā māka kaulana ʻo 430 (martensitic transformation), 409 (automotive interior), a me 446 (architectural).
ʻO Martensitic Stainless Steels: ʻO nā loea hoʻololi
ʻO nā kila kila Martensitic, i hōʻike ʻia e ka 400 series, hāʻawi i ka ikaika kiʻekiʻe a me ka paʻakikī ma muli o kā lākou martensitic microstructure. Eia nō naʻe, ʻoi aku ka liʻiliʻi o ka ductile a ʻoi aku ka maʻalahi o ka corrosion ma mua o nā kila stainless austenitic. Hoʻopili ʻia nā mea hoʻohana i nā ʻoki ʻoki, nā mea hana ʻoki, a me nā ʻāpana lole. ʻO nā māka maʻamau ʻo 410 (mea ʻokiʻoki), 420 (mea hoʻonaninani), a me 440 (paʻakikī kiʻekiʻe).
Duplex Stainless Steel: He Hui Mana Mana
ʻO ka Duplex stainless steel kahi hui like ʻole o nā hale austenitic a me ka ferritic e hāʻawi i kahi hui kūʻokoʻa o ka ikaika kiʻekiʻe, ke kūpaʻa corrosion, a me ka weldability. Hoʻonui ʻia kona ʻano chromium kiʻekiʻe i kona kūʻē ʻana i ke koʻikoʻi o ka chloride, kūpono ia no nā noi kai a me waho. ʻO nā māka kaulana ʻo 2205 (Oil & Gas), 2304 (Super Duplex), a me 2507 (Super Duplex).
ʻO ke kila paʻakikī o ka ua: Koa Paʻa Makahiki
ʻO nā kila kuhili ʻole paʻakikī paʻakikī, i hōʻike ʻia e nā māka 17-4PH a me X70, hiki ke hoʻonui i ko lākou ikaika a me ka paʻakikī ma o ke kaʻina hana mālama wela i kapa ʻia ʻo precipitation hardening. ʻO kā lākou kūpaʻa corrosion maikaʻi a me ke kūpaʻa dimensional e kūpono iā lākou no ka aerospace, nā ʻāpana valve, a me nā noi kiʻekiʻe.
E hoʻokele i ka honua o ke kila kila me ka hilinaʻi
Me kēia alakaʻi piha e like me kāu panana, hiki iā ʻoe ke hoʻokele i ka honua like ʻole o nā māka kila kila. Ma ka noʻonoʻo pono ʻana i nā hiʻohiʻona, nā noi, a me nā palena o kēlā me kēia ʻano, hiki iā ʻoe ke hoʻoholo i ka ʻike e kūpono i kāu mau pono kikoʻī a hōʻoia i ka hana lōʻihi mai kāu mau mea kila kila.
