Manaʻo pinepine ka poʻe e komo nā magnet i ke kila kila e hōʻoia i kona maikaʻi a me ka ʻoiaʻiʻo. Inā ʻaʻole ia e huki i nā huahana non-magnetic, manaʻo ʻia he maikaʻi a ʻoiaʻiʻo; ina e huki mai i na magnet, ua manaoia he hoopunipuni. ʻO ka ʻoiaʻiʻo, he ʻaoʻao hoʻokahi kēia, ʻaʻole maoli a hewa ʻole o ka ʻike.
Nui nā ʻano o ke kila kila, hiki ke hoʻokaʻawale ʻia i nā ʻāpana he nui e like me kā lākou hoʻonohonoho hoʻonohonoho ʻana i ka lumi wela:
1. ʻAno Austenitic: e like me 304, 321, 316, 310, etc.;
2. Martensite a ferrite ʻano: e like me 430, 420, 410, etc.;
ʻAʻole magnetic a nāwaliwali paha ʻo Austenite, ʻoiai ʻo martensite a i ʻole ferrite ka magnetic.
ʻO ka hapa nui o ke kila kila i hoʻohana mau ʻia no nā ʻāpana paipu hoʻonaninani he mea austenitic 304. ʻO ka ʻōlelo maʻamau, ʻaʻole magnetic a nāwaliwali nāwaliwali. Eia nō naʻe, ma muli o ka loli ʻana o ka haku mele ma muli o ka hoʻoheheʻe ʻana a i ʻole nā ʻano kaʻina hana like ʻole, hiki i ka magnetism ke hiki mai, akā ʻaʻole hiki ke manaʻo ʻia he hoʻopunipuni a i ʻole kūpono ʻole, he aha ke kumu?
E like me ka mea i ʻōlelo ʻia ma luna nei, ʻo ka austenite he non-magnetic a nāwaliwali paha, 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, e hana ʻia kahi mea liʻiliʻi o ka martensite a i ʻole ferrite i ka austenitic 304 stainless steel. kino kino. Ma kēia ʻano, e loaʻa i ka 304 stainless steel ka nāwaliwali nāwaliwali.
Eia kekahi, ma hope o ka hana anuanu o 304 stainless steel, e hoʻololi ʻia ka hoʻonohonoho hoʻonohonoho i martensite. ʻOi aku ka nui o ka deformation hana anu, ʻoi aku ka martensitic transformation, a ʻoi aku ka nui o ka magnetism o ke kila. E like me ka nui o nā ʻāpana kila,Φ76 paipu i hanaia. ʻAʻohe mea i ʻike ʻia i ka hoʻokomo magnetic, aΦHana ʻia nā paipu 9.5. No ka mea ʻoi aku ka nui o ka deformation kulou, e ʻike ʻia ka induction magnetic. ʻOi aku ka nui o ka hoʻololi ʻana o ka paipu ʻehā ʻehā 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.
I mea e hoʻopau loa ai i ka magnetism o ke kila 304 i hoʻokumu ʻia e nā kumu i luna, hiki ke hoʻihoʻi ʻia ka hale austenite paʻa ma o ka mālama ʻana i ka hopena wela, a laila e hoʻopau i ka magnetism.
ʻO ka mea nui, pono e kuhikuhi ʻia ʻo ka magnetism o 304 stainless steel ma muli o nā kumu i luna nei ʻaʻole i ka pae like me ka magnetism o nā mea kila kila, e like me 430 a me ke kila kalapona. I nā huaʻōlelo ʻē aʻe, ʻo ka magnetism o ke kila 304 e hōʻike mau ana i ka magnetism nāwaliwali.
Hōʻike kēia iā mākou inā he palupalu nāwaliwali ke kila kila a ʻaʻole loa he magnetism, pono e ʻike ʻia ʻo 304 a i ʻole 316 mea; inā loaʻa ka magnetism like me ke kila kalapona a hōʻike i ka magnetism ikaika, pono e ʻike ʻia ʻaʻole 304 mea.
ʻO Jindalai Steel Groupmanaʻo ʻoe i ke kūʻai ʻana i nā huahana kila kila, pono ʻoe e koho i nā huahana mai nā mea hana kaulana. Mai kuko i ke kumu kūʻai haʻahaʻa a e makaʻala i ka hoʻopunipuni ʻia. ʻO Jindalai Steel Group kahi ʻoihana kila kila nui a me ka ʻoihana kālepa e hoʻohui ana i ka pā kila kila ma ke kūʻai nui, ka hana ʻana, ka hale kūʻai a me ka hāʻawi ʻana. Ke hilinaʻi nei i ka hilinaʻi a me ke kōkua o nā hoa hana ma ka home a ma waho, ua ulu ka hui i hoʻokahi o nā ʻoihana nui e hoʻohui i ka hana a me ke kālepa ʻana i ka ʻoihana kila kila ma hope o nā makahiki he ʻumi o ka hoʻomohala ʻana a me ka ulu ʻana.
