ʻO 304 ke kila kila ka mea i hoʻohana nui ʻia i ka chromium-nickel stainless steel. Ma keʻano he kila i hoʻohana nuiʻia, he maikaʻi ke kūpaʻa corrosion, ka wela wela, ka ikaika haʻahaʻa haʻahaʻa a me nā mea mechanical; He hana wela maikaʻi e like me ke kuʻi ʻana a me ke kulou ʻana, a ʻaʻohe hanana hoʻopaʻapaʻa mālama wela (ka mahana hana -196 ℃ ~ 800 ℃).

Kila kohu ʻoleInox 304(AISI 304) ʻo ia ka mea hoʻohana nui ʻia o ke kila kila ma muli o kona ʻano mekini kaulike.

Eia kāna mau hiʻohiʻona nui o ka inox 304:

1. Pale ʻino

Kū'ē kiʻekiʻe i ka corrosioni loko o kahi ākea o nā kaiapuni, ʻoi aku ka maikaʻi o nā kūlana o ka lewa a me ka ʻike ʻana i nā kemika corrosive e like me nā waikawa a me nā chlorides.

Hana maikaʻi ʻia ma nā wahi i ʻike ʻia i ka makū a i ʻole ka haʻahaʻa.

2. Huina

Aia ma kahi o18% chromiuma8% nikela, i olelo pinepine ia18/8 kila kila.

Loaʻa pū kekahi i nā mea liʻiliʻi okalapona (max 0.08%), manganese, asilika.

3. Na Waiwai Mechanical

Ka ikaika tensile: A puni515 MPa (75 ksi).

E hāʻawi i ka ikaika: A puni205 MPa (30 ksi).

ʻO ka lōʻihi: A hiki i40%, e hōʻike ana i ka maikaʻi formability.

ʻoʻoleʻa: He palupalu a hiki ke paʻakikī i ka hana ma o ka hana anu.

4. Formability a me ka hana

Hoʻokumu maʻalahii loko o nā ʻano like ʻole ma muli o kona ductility maikaʻi loa, kūpono ia no ke kaha kiʻi hohonu, kaomi ʻana, a me ka piko.

Maikaʻi weldability, kūpono loa no nā ʻenehana wiliwili maʻamau.

Hiki ke hana anu: Hiki ke hooikaika nui ia e ka hana anu, aole nae ma ka lapaau wela.

5. Kū'ē wela

ʻO ke kūpaʻa ʻanaa hiki i870°C (1598°F)i ka hoʻohana manawaleʻa a hiki i925°C (1697°F)ma ka lawelawe mau.

ʻAʻole ʻōlelo ʻia no ka hoʻohana ʻana i nā kaiapuni e pili ana i ka ʻike mau ʻana i nā mahana ma luna425-860°C (797-1580°F)ma muli o ka pilikia o ka ua carbide, hiki ke hōʻemi i ka pale ʻana i ka corrosion.

6. Hoʻomaʻemaʻe a me nā hiʻohiʻona nani

Maʻalahi e hoʻomaʻemaʻe a mālamama muli o kona ʻili maʻalahi, ka mea e kūʻē i ka ulu ʻana o ka maʻi bacteria, i mea kūpono no ka hana ʻai a me nā lako kīhini.

Mālama i kahi ʻālohilohi a nanihoʻopau ʻili, e kaulana ana i ka hoʻolālā, nā lako kīhini, a me nā mea hoʻonani.

7. Non-Magnetic

ʻO ka maʻamaunon-magnetici kona ʻano annealed, akā hiki ke lilo i mea hoʻokalakupua ma hope o ka hana anu.

8. Nā noi

Hoʻohana nui ʻia i nā lako hana meaʻai, nā lako kīhini, nā ipu kemika, nā papa hana hale, a me nā mea lapaʻau.

He kūpono no nā kaiapuni e koi ana i ka pale ʻana i ka corrosion maikaʻi, ka lōʻihi, a me ka maʻalahi o ka hana ʻana.

9. Kūʻai-Pono

ʻOi aku ke kumu kūʻai ma mua o nā kila kila kila kiʻekiʻe (e like me 316) ʻoiai e hāʻawi ana i nā waiwai holoʻokoʻa maikaʻi loa, e kaulana ai ia no nā noi he nui.

10.Kūʻē i nā ʻAka

Kūleʻa i ka nui o nā waikawa organika me nā ʻakika inorganic haʻahaʻa haʻahaʻa, ʻoiai ʻaʻole hiki ke hana maikaʻi i nā wahi ʻakika nui a i ʻole chloride-waiwai (e like me ka wai kai), kahi i makemake ʻia ai ke kila kila 316.

ʻO Inox 304 kahi koho kila kila maikaʻi loa a puni no nā ʻano like ʻole a me ka hoʻohana ʻana, ke kaupaona ʻana i ke kumukūʻai, ka lōʻihi, a me ka hana.

ʻO nā pono a me nā hiʻohiʻona o ka inox 304:

1. Kū'ē wela kiʻekiʻe
ʻO 304 kila kila e aloha ʻia e ka hapa nui o nā kānaka no nā kumu he nui. No ka laʻana, he maikaʻi ke kūpaʻa wela kiʻekiʻe, ʻaʻole i hoʻohālikelike ʻia e ke kila kuhili maʻamau. Hiki i ka 304 kila kila ke kū i nā wela kiʻekiʻe a hiki i 800 degere a hiki ke hoʻohana maoli ʻia i nā manawa like ʻole o ke ola.

2. Ke kū'ē i ka corrosion
ʻO 304 kila kila maikaʻi loa i ka pale ʻana i ka corrosion. No ka mea, hoʻohana ʻo ia i nā mea chromium-nickel, paʻa loa nā waiwai kemika a ʻaʻole maʻalahi ke ʻino. No laila, hiki ke hoʻohana ʻia ka 304 stainless steel ma ke ʻano he mea anti-corrosion.

3. ʻOʻoleʻa kiʻekiʻe
Loaʻa i ka 304 stainless steel ke ʻano o ka paʻakikī kiʻekiʻe, i ʻike ʻia e nā poʻe he nui. No laila, e hana nā kānaka i nā huahana like ʻole, a ʻoi aku ka kiʻekiʻe o ka huahana.

4. Haʻahaʻa kepau maʻiʻo
ʻO ke kumu ʻē aʻe o ke koho ʻana i ke kila kila 304 ʻo ia ka liʻiliʻi o ke alakaʻi a ʻaʻohe mea ʻino i ke kino. No laila, ua kapa ʻia ʻo ia ke kila kila kila a hiki ke hoʻohana pololei ʻia e hana i nā mea ʻai.

No ke aha ʻo inox 304 kekahi o nā māka kila kila kila kaulana loa

ʻO ka Inox 304 kekahi o nā māka kila kila ma muli o nā kumu nui:

1. Pale ʻino

• Hāʻawi ia i ke kūpaʻa maikaʻi loa i ka corrosion ma nā ʻano kaiapuni, kūpono ia no nā noi i loko a me waho.

2. ʻAno ʻano

• Hiki i kona haku mele 'ana ke ho'ohana 'ia ma nā 'oihana he nui, e like me ka mea'ai a me ka mea inu, ka hale ho'olālā, ka'a ka'a, a me ka lā'au lapa'au.

3. Na Waiwai Mekani maikai

• Loaʻa iā ia ka ikaika tensile kiʻekiʻe a me ka ductility maikaʻi, hiki iā ia ke kū i ke koʻikoʻi mechanical a me ka deformation me ka ʻole o ka haki ʻana.

4. Maalahi o ka hana ana

• Hana maʻalahi ʻo Inox 304 a hana ʻia i nā ʻano like ʻole a me nā nui, e hoʻomaʻamaʻa i nā kaʻina hana.

5. Weldability

• Hiki ke maʻalahi i ka welded me ka hoʻohana ʻana i nā ʻenehana maʻamau a pau, i kūpono ia no nā noi kūkulu.

6. Na Waiwai Maemae

• ʻO kona ʻili maʻemaʻe a me ke kūpaʻa ʻana i ka maʻi bacteria e kūpono ia no ka hoʻomaʻamaʻa ʻana i ka meaʻai a me nā noi olakino, kahi mea koʻikoʻi ka maʻemaʻe.

7. Kūʻai-Pono

• ʻOiai e hāʻawi ana i nā waiwai maikaʻi loa, ʻoi aku ka liʻiliʻi o ke kumukūʻai ma mua o nā kila kila kila maikaʻi ʻē aʻe, e lilo ia i koho waiwai no nā papahana he nui.

8. Non-Magnetic

• I kona kūlana annealed, ʻaʻole ia he magnet, he mea nui ia no kekahi mau noi kahi e pilikia ai ka magnetism.

9. Hoʻopiʻi nani

• Mālama ʻo ia i kahi hoʻopau nani, kūpono ia no ka hoʻolālā a me nā noi hoʻonaninani.

10.Loaʻa honua

• Ma ke ʻano he alloy maʻamau, hoʻopuka nui ʻia a loaʻa maʻalahi, e maʻalahi ka loaʻa ʻana no nā mea hana a me nā mea kūʻai aku.

Hoʻohui ʻia kēia mau hiʻohiʻona e hana i ka inox 304 i mea hele-i no ka nui o nā noi, e alakaʻi ana i kona hoʻohana ākea a ʻike ʻia.

Hoʻoholo:

ʻIke ʻia ʻo Inox 304 a i ʻole Stainless Steel 304 no kona kūpaʻa ʻana i ka corrosion maikaʻi, ka weldability maikaʻi a me ka ikaika kiʻekiʻe. Loaʻa iā ia ka 18% chromium a me ka 8% nickel a kūpono ia no kahi ākea o nā noi. ʻO kēia mau waiwai e hoʻohana nui ʻia i ka pae kila stainless a puni ka honua.
