I kēia manawa, nui nā huahana ʻoihana e hana ʻia me ke kaula uwea kila kila.I mea e ʻike ai i ke kila kila kila hoʻopunipuni a haʻahaʻa, hiki ke lawe ʻia kekahi mau ana a me nā ʻano hana.Akā ʻaʻole ʻike ka nui o nā mea kūʻai aku i ke ala e ʻike ai, ua helu ʻia nā ʻano ʻike aʻe no ʻoe.
ʻO ke ʻano hoʻāʻo Magnetic ka ʻokoʻa maʻamau ma waena o ka austenitic stainless steel a me ka ferritic stainless steel ala maʻalahi, austenitic stainless steel hewa magnetic steel, akā ma hope o ka hana anu ma lalo o ke kaomi nui e loaʻa kahi magnetic liʻiliʻi;Akā ʻo ke kila chrome maʻemaʻe a me ke kila hao haʻahaʻa he kila magnetic ikaika.
ʻO kahi hiʻohiʻona kupaianaha o ke kaula uea kila kila ʻo ia kona kūpaʻa ʻana i ka corrosion i ka concentrated nitric acid a me ka dilute nitric acid, kahi e maʻalahi ai ke hoʻokaʻawale ʻia mai ka hapa nui o nā metala a i ʻole nā mea hao.Akā, kiʻekiʻe kalapona 420 a me 440 kila i loko o ka nitricʻakika wahi ho'āʻo ua iki corroded, non-ferrous metala halawai concentrated nitricʻakika ua koke corroded, a dilute nitricʻakika i ikaika corrosion ma carbon kila.
He ala maʻalahi ka hoʻāʻo ʻana i ke kiko keleawe keleawe e ʻike koke i ke kila kalapona maʻamau a me nā ʻano kaula uea kuhili ʻole.ʻO ka nui o ka hopena keleawe sulfate i hoʻohanaʻia he 5% -10%.Ma mua o ka ho'āʻo kiko, pono e wehe pono ʻia ka ʻāpana hoʻokolohua mai ka ʻaila a i ʻole nā mea haumia ʻē aʻe, a ʻo kahi wahi liʻiliʻi e poni ʻia e ka mīkini wili a i ʻole ka lole wili palupalu, a laila hāʻule ka wai hoʻāʻo i kahi wili.ʻO ke kila kalapona maʻamau a i ʻole ka hao i loko o kekahi mau kekona e hana i kahi papa o waho metala keleawe, a ʻo ka ʻili o ke kila kila ʻaʻole e hoʻohua ke keleawe a hōʻike i ke kala keleawe.
