ʻO ke kaʻina hana hana o ka pahi kila kila, ka ʻō a me ka puna liʻiliʻi no ka ʻaina ahiahi e hana ʻia e nā kaʻina hana paʻakikī he nui e like me ka stamping, welding a me ka wili ʻana
Hiki ke hoʻokaʻawale ʻia nā ipu ʻaina kila kila o ka 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 i hoʻokumu ʻia e nā kumu kūlohelohe. Ua kapa ʻia ʻo ia he kila kila. Ma JIS, ua kapa ʻia ʻo ia he code 430, no laila ua kapa ʻia hoʻi ʻo ia he kila kila 430. Eia naʻe, ʻaʻole hiki i ke kila kila 430 ke pale aku i ka oxidation i hoʻokumu ʻia e nā kemika i ka lewa. ʻAʻole hoʻohana pinepine ʻia ke kila kila 430 no kekahi manawa, akā e oxidized mau ʻia (popo) ma muli o nā kumu kūlohelohe ʻole.
18-8 kila kila:
Hiki i ka hao + 18% chromium + 8% nickel ke kū'ē i ka oxidation kemika. ʻO kēia kila kila he helu 304 ma ke code JIS, no laila ua kapa ʻia hoʻi he 304 kila kila.
18-10 kila kila:
Eia nō naʻe, ʻoi aku ka nui o nā ʻāpana kemika i ka lewa, a hiki i ka 304 ke popo i kekahi mau wahi haumia loa; No laila, e hana ʻia kekahi mau huahana kiʻekiʻe me ka 10% nickel e ʻoi aku ka paʻa a me ke kūpaʻa i ka pala. Ua kapa ʻia kēia ʻano kila kila he 18-10 kila kila. Ma kekahi mau kuhikuhi no nā mea ʻaina, aia kahi ʻōlelo e like me "ka hoʻohana ʻana i ka 18-10 kila kila lapaʻau holomua loa".
Wahi a ka loiloi o ke kikowaena noiʻi ʻikepili, hiki ke hoʻokaʻawale ʻia ke kila kila i ʻekolu mau māhele: ke kila kila austenitic, ke kila kila ferritic a me ke kila kila martensitic. ʻO nā ʻāpana nui o ke kila kila he hao, chromium a me nā mea hoʻohuihui nickel. Eia kekahi, loaʻa pū kekahi mau mea trace e like me ka manganese, titanium, cobalt, molybdenum a me cadmium, ka mea e hoʻopaʻa ai i ka hana o ke kila kila a he kūpaʻa i ka popo a me ka pale ʻana i ka pala. ʻAʻole maʻalahi ka magnetized o ke kila kila Austenitic ma muli o ke ʻano kūikawā o ka ʻano molekala kūloko.
