No ke aha i hoʻohana ʻia ai ʻo 304 Stainless Steel Pipe
I ke ola, hoʻohana pinepine mākou i ka magnetism o nā paipu e hoʻoholo ai inā he maikaʻi a maikaʻi ʻole paha ke kila kila, akā ʻoiaʻiʻo, ʻaʻole ʻepekema kēia ʻano. No ka laʻana, hiki i kā mākou mau ʻāpana zinc tube a me nā ʻāpana keleawe ke hoʻohālike i ke ʻano a me ke kala o ke kila kila, ʻaʻole hoʻi lākou he magnetic, he mea maʻalahi ke kuhihewa ʻia no ke kila kila. ʻO ke kila 304 a mākou e hoʻohana pinepine ai i kēia manawa, ma hope o ka hana anu, E loaʻa pū kekahi mau degere like ʻole o ka magnetism paipu, no laila ʻaʻole hiki iā mākou ke hoʻoholo inā he maikaʻi a maikaʻi ʻole paha ke kila kila ma ka loaʻa ʻana o kahi paipu magnetic. No ke aha 304 Paipu kila kila he manekini.
Ma keʻano laulā, hiki ke hoʻokaʻawale ʻia ka paipu kuhili kila kila i ʻelua ʻano e like me kona ʻano i ka lumi wela. ʻO kekahi he paipu kila ʻole austenitic, e like me ka paipu 304321, 316 paipu, 310 paipu, a me nā mea ʻē aʻe, a ʻo kekahi ʻo ka paipu martensite a i ʻole ka ferritic stainless steel paipu, e like me 430420 paipu, 410 paipu, etc. mākia.
'Ōlelo pinepine mākou i ka 304 stainless steel he non-magnetic tubular stainless steel, ʻo ia hoʻi, ʻoi aku ka haʻahaʻa o kāna helu magnetic ma mua o kahi waiwai. ʻO ia hoʻi, loaʻa i ke kila kuhili ʻole ke ʻano o ka magnetism tube. ʻO ka austenitic stainless steel i hāpai ʻia ma mua he non-magnetic a nāwaliwali paha, ʻoiai ʻo ka ferritic a me ka martensitic stainless steel he mau waiwai tubular magnetic, ʻo ia ma muli o ka hoʻokaʻawale ʻana a i ʻole nā paipu mālama wela kūpono ʻole i ka wā o ka hoʻoheheʻe ʻana. Paipu Kuhiliʻole. Eia kekahi, ma hope o ka hana anu, e hoʻololi ʻia ke ʻano o 304 stainless steel tube i martensite. Me ka nui o ka deformation o ka hoʻoheheʻe ʻana i ke anuanu, ʻoi aku ka nui o nā paipu hoʻololi martensite, ʻoi aku ka ikaika o ka magnetism.
No laila, ua hoʻoholo ʻia nā waiwai magnetic o nā mea e ka maʻamau o ka hoʻonohonoho molecular o nā paipu a me ka isotropy o ka uila uila, hiki ke noʻonoʻo ʻia he ʻano kino o nā mea, ʻoiai ʻo ke kūpaʻa ʻana o nā mea i hoʻoholo ʻia e ka hoʻohui kemika o nā mea, ʻo ia nā mea kemika o nā mea a me nā paipu, a ʻaʻohe mea pili inā he magnetic a ʻaʻole paha nā mea.
