I ke koho ʻana i kahi papa kila kila (SS) no kāu noi a i ʻole prototype, he mea nui e noʻonoʻo inā pono nā waiwai magnetic. No ka hoʻoholo ʻana i kahi hoʻoholo naʻauao, he mea nui e hoʻomaopopo i nā mea e hoʻoholo ai inā he magnetic a ʻaʻole paha kahi papa kila kila.
ʻO nā kila kila he mau mea hao i kaulana no ko lākou kūpaʻa maikaʻi loa i ka pala. Aia nā ʻano kila kila like ʻole, me nā māhele mua he austenitic (e laʻa, 304H20RW, 304F10250X010SL) a me ferritic (hoʻohana pinepine ʻia i nā noi kaʻa, nā lako kīhini, a me nā lako ʻoihana). Loaʻa i kēia mau māhele nā mea hoʻohui kemika like ʻole, e alakaʻi ana i kā lākou mau ʻano magnetic ʻokoʻa. ʻO nā kila kila Ferritic he magnetic, ʻoiai ʻaʻole nā kila kila austenitic. ʻO ka magnetism o ke kila kila ferritic e kū mai ana mai ʻelua mau kumu nui: kona nui o ka hao a me kona hoʻonohonoho ʻana i ke ʻano ma lalo.
Hoʻololi mai nā ʻĀpana Non-Magnetic a i nā ʻĀpana Magnetic i ke kila kila
ʻO nā mea ʻelua304a hāʻule nā kila kila kila 316 ma lalo o ka māhele austenitic, ʻo ia hoʻi, ke hoʻomaʻalili lākou, mālama ka hao i kona ʻano austenite (gamma iron), kahi pae non-magnetic. Pili nā pae like ʻole o ka hao paʻa i nā ʻano kristal ʻokoʻa. I kekahi mau mea hao ʻē aʻe, hoʻololi kēia pae hao wela kiʻekiʻe i kahi pae magnetic i ka wā e hoʻomaʻalili ai. Eia nō naʻe, ʻo ke alo o ka nickel i loko o nā mea kila kila e pale aku i kēia hoʻololi pae i ka wā e hoʻomaʻalili ai ka mea hao i ka mahana o ka lumi. ʻO ka hopena, hōʻike ka kila kila i kahi susceptibility magnetic kiʻekiʻe iki ma mua o nā mea non-magnetic loa, ʻoiai ke noho mau nei ia ma lalo o ka mea i manaʻo ʻia he magnetic.
He mea nui e hoʻomaopopo ʻaʻole pono ʻoe e manaʻo e ana i kēlā ʻano haʻahaʻa o ka magnetic susceptibility ma kēlā me kēia ʻāpana o ke kila kila 304 a i ʻole 316 āu e ʻike ai. ʻO kēlā me kēia kaʻina hana e hiki ai ke hoʻololi i ke ʻano kristal o ke kila kila hiki ke hoʻololi i ka austenite i loko o nā ʻano ferromagnetic martensite a i ʻole ferrite o ka hao. ʻO ia mau kaʻina hana e komo pū me ka hana anu a me ka hoʻopili ʻana. Eia kekahi, hiki i ka austenite ke hoʻololi koke i martensite ma nā mahana haʻahaʻa. No ka hoʻohui ʻana i ka paʻakikī, ua hoʻopili ʻia nā waiwai magnetic o kēia mau alloys e kā lākou haku mele ʻana. ʻOiai i loko o nā pae ʻae ʻia o ka ʻokoʻa o ka nickel a me ka chromium, hiki ke ʻike ʻia nā ʻokoʻa i ʻike ʻia i nā waiwai magnetic no kahi alloy kikoʻī.
Nā Manaʻo Kūpono no ka Wehe ʻana i nā ʻĀpana Kila Kinoea
ʻO 304 a me316 kila kilahōʻike i nā ʻano paramagnetic. No laila, hiki ke huki ʻia nā ʻāpana liʻiliʻi, e like me nā spheres me nā diameters mai kahi o 0.1 a 3mm, i nā mea hoʻokaʻawale magnetic ikaika i kau ʻia ma ke ʻano kūpono i loko o ke kahawai huahana. Ma muli o ko lākou kaumaha a, ʻoi aku ka nui, ko lākou kaumaha e pili ana i ka ikaika o ka huki magnetic, e pili ana kēia mau ʻāpana liʻiliʻi i nā magnet i ka wā o ke kaʻina hana.
Ma hope iho, hiki ke wehe pono ʻia kēia mau ʻāpana i ka wā o nā hana hoʻomaʻemaʻe magnet maʻamau. Ma muli o kā mākou nānā pono ʻana, ua ʻike mākou he ʻoi aku ka nui o ka paʻa ʻana o nā ʻāpana kila kila 304 i ke kahe ʻana i hoʻohālikelike ʻia me nā ʻāpana kila kila 316. ʻO ke kumu nui o kēia, ʻo ia ke ʻano magnetic kiʻekiʻe iki o ke kila kila 304, ka mea e ʻoi aku ai ka pane ʻana i nā ʻano hana hoʻokaʻawale magnetic.
