Ma ke ola maoli, manaʻo ka hapa nui o ka poʻekila kohu ʻole ʻAʻole ia he magnetic, a he mea ʻepekema ʻole ka hoʻohana ʻana i nā mea magnet e ʻike ai i ke kila kila.Manaʻo pinepine ka poʻe e hoʻopili nā magnet i nā mea kila kila e hōʻoia i ko lākou maikaʻi a me ka ʻoiaʻiʻo.ʻAʻole maikaʻi lākou a ʻaʻole magnetic.Ua manaoia he maikai a he oiaio;inā he magnetic, manaʻo ʻia he mau huahana hoʻopunipuni.He ala hoʻokahi wale nō kēia a hiki ʻole ke ʻike i nā hewa.Nui nā ʻano o ke kila kila, hiki ke hoʻokaʻawale ʻia i nā ʻāpana he nui e like me ka hoʻonohonoho hoʻonohonoho ʻana i ka lumi wela.

1. ʻAno Austenite e like me 304, 321, 316, 310, etc.;

2. Martensite a ferrite ʻano like me 430, 420, 410, etc.;ʻO ke ʻano Austenitic ʻaʻole magnetic a nāwaliwali paha, a ʻo ka martensite a i ʻole ferrite ka magnetic.ʻO ka hapa nui o ke kila kuhili ʻole i hoʻohana maʻamau ʻia no nā ʻāpana paipu hoʻonaninani ʻo austenitic 304, ʻo ia ka mea maʻamau non-magnetic a nāwaliwali paha.Eia nō naʻe, ma muli o ka loli ʻana o ka haku mele ʻana a i ʻole nā ​​kūlana kaʻina hana ʻē aʻe i hana ʻia e ka hoʻoheheʻe ʻana, ʻike ʻia paha ka magnetism, akā ʻaʻole hiki ke manaʻo ʻia he aha ke kumu o ka hoʻopunipuni a i ʻole kūpono ʻole?E like me ka mea i hōʻike ʻia ma luna nei, ʻaʻole magnetic a nāwaliwali paha ka austenite, ʻoiai ʻo martensite a i ʻole ferrite ka magnetic.Ma muli o ka hoʻokaʻawale ʻana o nā ʻāpana a i ʻole ka mālama wela kūpono ʻole i ka wā o ka hoʻoheheʻe ʻana.ʻO kahi mea liʻiliʻi o ka martensite a i ʻole ferrite i loko o ka austenitic 304 stainless steel e hana ʻia.kino kino.Ma kēia ala, e loaʻa i ka 304 stainless steel nā waiwai magnetic nāwaliwali.Eia kekahi, ma hope o ka hana anu ʻana o 304 stainless steel, e hoʻololi ʻia ka hale i martensite.ʻOi aku ka nui o ka deformation hana anuanu, ʻoi aku ka nui o ka hoʻololi ʻana o martensite a ʻoi aku ka nui o nā waiwai magnetic o ke kila.E like me nā kāʻei kila,ΦHoʻopuka ʻia nā paipu 76 me ka ʻike ʻole ʻia o ka induction magnetic, aΦHana ʻia nā paipu 9.5.No ka mea, ʻoi aku ka nui o ka deformation kulou, ʻoi aku ka ʻike o ka induction magnetic, a ʻoi aku ka nui o ka deformation o ka pahu square rectangular ma mua o ka paipu poepoe, ʻoi aku ka ʻāpana kihi, ʻoi aku ka ikaika o ka deformation a ʻoi aku ka maopopo o ka magnetism.No ka hoʻopau ʻana i nā waiwai hypnotic o ke kila 304 i hoʻokumu ʻia e nā kumu i luna aʻe, hiki ke hoʻihoʻi a hoʻopaʻa ʻia ke ʻano austenite e ka mālama ʻana i ka wela wela, a laila e hoʻopau i nā waiwai magnetic.ʻO ka mea kūikawā, ʻo ka magnetism o 304 stainless steel i hoʻokumu ʻia e nā mea i luna nei ʻaʻole i ka pae like me nā mea ʻē aʻe o ke kila kila, e like me 430 a me ke kila kalapona.ʻO kēlā wale nō, ʻo ka magnetism o 304 steel e hōʻike mau ana i ka magnetism nāwaliwali.Hōʻike kēia iā mākou inā he palupalu nā mea kila kila a ʻaʻole paha, pono e hoʻokolokolo ʻia ʻo 304 a i ʻole 316;inā like ia me ke kila kalapona, hōʻike ia i ka magnetism ikaika, no ka mea, ua hoʻoholo ʻia ʻaʻole 304. ʻO 304 a me 316 he austenitic stainless steel a hoʻokahi-phase.He palupalu nawaliwali.
