He aha ka ʻokoʻa o ke kila kila 304,304L,316,316L?

He aha ke kila kila?

ʻAʻole maʻamau ka mea kila kila i ko mākou ola i kēlā me kēia lā, akā ua hoʻohana nui ʻia i ka ʻoihana kaumaha, nā ʻoihana māmā a me nā noi ʻoihana kūkulu. Kūleʻa ʻia ke kila ʻakika kūpaʻa ʻole he kila kila. Hoʻokumu ʻia ia me ke kila kuhiliʻole a me ke kila ʻakika. I ka pōkole, kapa ʻia ke kila hiki ke pale aku i ka ʻinoʻino o ka lewa, a ʻo ke kila hiki ke kūʻē i ka hoʻoheheʻe ʻana i nā mea hoʻoheheʻe kemika, ua kapa ʻia ʻo ia he kila kūpaʻa wai. ʻO nā ʻano kila kuhili ʻole i hoʻohana mau ʻia ʻo 304, 304L, 316, 316L, ʻo ia nā 300 series steels o austenitic stainless steel. He aha ka manaʻo o 304, 304L, 316, 316L? ʻOiaʻiʻo, pili kēia i kakila kila kila kūlana kila, ʻokoʻa nā kūlana o nā ʻāina like ʻole, e ʻoluʻolu e nānā i ka papa ma lalo no nā kikoʻī.

304kila kohu ʻole

ʻO ka 304 stainless steel he kila ākea a hoʻohana nui ʻia me ke kūpaʻa corrosion maikaʻi, ke kūpaʻa wela, ka ikaika haʻahaʻa haʻahaʻa a me nā waiwai mechanical; maikaʻi ka hana hana a me ka paʻakikī kiʻekiʻe. Hoʻohana nui ʻia ia e hana i nā mea hana a me nā ʻāpana e pono ai ka hana piha maikaʻi (ka pale ʻana i ka corrosion a me ka formability). He kū'ē i ka corrosion i ka lewa. Inā he lewa ʻoihana a he wahi haumia nui paha, pono e hoʻomaʻemaʻe ʻia i ka manawa e pale ai i ka corrosion. He kū'ē i ka corrosion i ka lewa. Inā he lewa ʻoihana a he wahi haumia nui paha, pono e hoʻomaʻemaʻe ʻia i ka manawa e pale ai i ka corrosion. ʻO 304 kila kuhiliʻole he kila kila i ʻike ʻia ma ka ʻāina.

316kila kohu ʻole

ʻO ka ʻokoʻa nui ma waena o 316 a me 304 i ka haku mele ʻana ʻo 316 ka Mo, a ʻike ʻia he ʻoi aku ka maikaʻi o ka 316 i ka corrosion a ʻoi aku ke kūpaʻa i ka corrosion ma nā wahi wela kiʻekiʻe ma mua o 304. Hiki ke hoʻohana ʻia ma lalo o ka wela wela. nā kūlana; ka paʻakikī o ka hana maikaʻi (nāwaliwali a i ʻole ka magnet ma hope o ka hana ʻana); non-magnetic ma ke kūlana hoʻonā paʻa; maikaʻi kuʻihao hana. Ka laulā o nā noi, e like me kemika, dye, pepa, oxalic acid, fertilizer a me nā mea hana ʻē aʻe, ʻoihana meaʻai, nā mea hana ma nā kahakai, kūikawā nonā kānana kila kilaetc.

“L”

E like me kā mākou e ʻike ai, e hōʻike ʻia nā metala me ka carbide i hoʻemi ʻia ma mua o ka maʻiʻo maʻamau ma o ka hoʻohui ʻana i kahi "L" ma hope o ka papa-e like me 316L, 304L. No ke aha mākou e hōʻemi ai i nā carbide? ʻO ka mea nui e pale i ka "corrosion intergranular". Intergranular corrosion, ka ua o ka carbide i ka wā kiʻekiʻe-mehana kuʻihao o metala, hoʻopau i ka pilina ma waena o nā hua aniani, e hōʻemi nui i ka ikaika mechanical o ka metala. A paʻa mau ka ʻili metala, akā ʻaʻole hiki ke kūpaʻa i ke kīkēkē, no laila he ʻino weliweli loa ia.

304Lkila kohu ʻole

Ma ke ʻano he kila haʻahaʻa haʻahaʻa 304, ua like kona kūpaʻa corrosion me ke kila 304 ma lalo o nā kūlana maʻamau, akā ma hope o ke kuʻi ʻana a i ʻole ka hoʻoluhi koʻikoʻi, ʻoi aku ka maikaʻi o kona kūʻē ʻana i ka corrosion intergranular. Hiki iā ia ke mālama i ke kūpaʻa corrosion maikaʻi me ka mālama ʻole ʻana i ka wela a hiki ke hoʻohana ʻia ma -196 ℃ ~ 800 ℃. 

316Lkila kohu ʻole

E like me ka haʻahaʻa-carbon moʻo o 316 kila, me ka like me ka 316 kila, he maikai intergranular corrosion kū'ē. Hiki ke hoʻohana ʻia i nā huahana me nā koi kiʻekiʻe no ka anti-intergranular corrosion, a me nā mīkini waho i loko o nā ʻoihana kemika, lanahu, a me ka ʻaila, nā mea kanu kemika a me nā māla ʻē aʻe. ʻOi aku ka maʻalahi o ka corrosion intergranular ʻaʻole ia he ʻoi aku ka maʻalahi o nā mea kalapona haʻahaʻa ʻole i ka corrosion. Ma kahi kiʻekiʻe-chlorine kaiapuni, ʻoi aku ka kiʻekiʻe o kēia naʻau. ʻO ka maʻiʻo Mo o 316L e hoʻoikaika maikaʻi i ke kila i ka pitting corrosion a hiki ke hoʻohana pono ʻia i nā wahi i loaʻa nā ion halogen e like me Cl-.

ʻO HENGKO stainless steel filter element i hana ʻia me 316 a me 316L, loaʻa iā ia ka maikaʻi o ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa ʻana o ka corrosion maikaʻi, ka ikaika kiʻekiʻe, a me nā loulou nānā pono e hōʻoia i ka maikaʻi o nā huahana i waho o ka hale hana i hala i nā kuʻuna.

Eia ka hoʻohālikelike ʻana i nā ʻokoʻa nui o nā waiwai a me nā ʻano o nā ʻano kila kila 304, 304L, 316, a me 316L:

1. Hoʻohui: 316 a me 316L he molybdenum hou aʻe e hoʻonui ai i ko lākou kūʻē ʻana i ka corrosion, ʻoi aku hoʻi ma nā wahi chloride.

2. Nā Pono Mechanical: ʻO nā ʻano like ʻole 'L' (304L a me 316L) ma ke ʻano he haʻahaʻa iki ka ikaika ma muli o kā lākou ʻike kalapona liʻiliʻi, akā hāʻawi lākou i ka maikaʻi weldability.

3. Kū'ē Kū'ē: 316 a me 316L iʻoi aku ka maikaʻi ma ka paleʻana i ka corrosion i hoʻohālikelikeʻia me 304 a me 304L,ʻoi aku ma ka moana a me ka chloride kiʻekiʻe.

4. Hiki ke hoʻopololei: Hāʻawi nā ʻano ʻokoʻa 'L' (304L a me 316L) i ka ʻoi aku ka maikaʻi ma muli o ka hōʻemi ʻana o ka maʻi kalapona.

5. Weldability: ʻO ka mea i hoʻemi ʻia ke kalapona ma 304L a me 316L e hōʻemi i ka pilikia o ka ua carbide i ka wā wili, e hoʻolilo iā lākou i kūpono no nā noi welded ma mua o ko lākou mau hoa ʻole L.

6. Nā noi: ʻO nā noi i hāʻawiʻia he mau hiʻohiʻona wale nō, a hiki ke hoʻohanaʻia kēlā me kēiaʻano o ke kila kila ma nā mea'ē aʻe he nui ma muli o nā koi kiko'ī.

'Ōlelo Aʻo: E ʻokoʻa paha nā waiwai kikoʻī ma muli o ka mea hana a me nā kūlana kikoʻī o ka hana. E nānā mau i ka ʻikepili a ka mea hana hana no nā kikoʻī kikoʻī.

ʻO ka mea kānana kila kila i nā pores ea pololei, a ua like nā pores kānana a hoʻohele like ʻia; Maikaʻi ka ea permeability, ka wikiwiki o ke kinoea-wai kahe a me ka puʻunaue like ʻole. Aia nā ʻano kikoʻī nui a me nā ʻano hale e koho ai, a hiki ke hoʻopili ʻia e like me nā pono. Hoʻohui maikaʻi ʻia ka ʻāpana wili kila kila me ka pūpū vented, paʻa a ʻaʻole hāʻule a nani; hiki ke kūkulu pololei ʻia i loko o ka pūpū i hoʻoheheʻe ʻia me kahi hiʻohiʻona piha a ʻaʻohe mea paʻa hou.

Pioloke paha ʻoe e pili ana i nā ʻokoʻa ma waena o ke kila kila 304, 304L, 316, a me 316L?

Mai hopohopo, hiki i kā mākou hui loea ma HENGKO ke kōkua iā ʻoe e hoʻomaopopo i nā ʻokoʻa a loaʻa ke koho maikaʻi loa no kāu papahana a i ʻole noi.

Kāhea iā mā˚oui kēia lā e hoʻomaka a hana i ka hana mua i ka hoʻoholo ʻana i ka ʻike.
