Auwe, pēlā i hana ʻia ai ka ipu ʻaina kila.

ʻO ke kaʻina hana o ka pahi kila kila, ka ʻōpala a me ka puna liʻiliʻi no ka ʻaina ahiahi e hana ʻia e nā kaʻina hana paʻakikī e like me ka stamping, welding a me ka wili.

Hiki ke hoʻokaʻawale ʻia nā papa ʻaina kila kila hale i 201, 430, 304 (18-8) a me 18-10.

430 kila kila:
ʻO ka hao + ʻoi aku ma mua o 12% chromium hiki ke pale i ka oxidation ma muli o nā kumu kūlohelohe.Kapa ʻia ʻo ia he kila kila.Ma JIS, ua kapa ʻia ʻo 430, no laila ua kapa ʻia ʻo 430 stainless steel.Eia nō naʻe, ʻaʻole hiki i ka 430 stainless steel ke pale i ka oxidation i hana ʻia e nā kemika i ka lewa.ʻAʻole hoʻohana pinepine ʻia ʻo 430 stainless steel no kekahi manawa, akā e hoʻoheheʻe ʻia (rusted) ma muli o nā kumu kūlohelohe.

18-8 kila kila:
Hiki i ka hao + 18% chromium + 8% nickel ke pale aku i ka oxidation kemika.ʻO kēia kila kila ka helu 304 ma ke code JIS, no laila ua kapa ʻia ʻo 304 stainless steel.

18-10 kila kila:
Eia naʻe, ʻoi aku ka nui o nā mea kemika i ka lewa, a hiki i ka 304 e ʻōpala ma kekahi mau wahi haumia nui;No laila, e hana ʻia kekahi mau huahana kiʻekiʻe me 10% nickel i mea e ʻoi aku ka lōʻihi a me ka pale ʻana i ka corrosion.Kapa ʻia kēia ʻano kila kila he 18-10 kila kila.Ma kekahi mau ʻōlelo aʻoaʻo papa ʻaina, aia kekahi ʻōlelo e like me "hoʻohana ʻana i ka 18-10 ʻoi loa ke kila kila kila".

Wahi a ka loiloi o ke kikowaena noiʻi ʻikepili, hiki ke hoʻokaʻawale ʻia ke kila kila i ʻekolu mau ʻāpana: austenitic stainless steel, ferritic stainless steel a me martensitic stainless steel.ʻO nā mea nui o ke kila kila he hao, chromium a me nickel alloys.Eia kekahi, loaʻa iā ia nā mea trace e like me ka manganese, titanium, cobalt, molybdenum a me cadmium, ka mea e hoʻokō ai i ka hana o ke kila kila a me ke kūpaʻa ʻana a me ka pale ʻana i ka corrosion.ʻAʻole maʻalahi ka hoʻohana ʻia ʻana o ke kila kila Austenitic ma muli o ke ʻano o ke ʻano molekala kūloko.
