410 vs

2025-06-27

Introduction to 410 and 304 Ke kila kila:ʻO 410 a me 304 mau kila kila ʻelua mau māka hana maʻamau me nā waiwai like ʻole. ʻO ka papa 410 he 400-series martensitic stainless steel i loaʻa ma kahi o 11.5–13.5% chromium a me ka nickel haʻahaʻa loa. He magnetic a hiki ke mālama ʻia i ka wela i ka ikaika kiʻekiʻe a me ka paʻakikī. ʻO ka hoʻohālikelike ʻana, ʻo 304 he 18/8 austenitic stainless steel me kahi 18-20% chromium a me 8-11% nickel. ʻO ka maʻiʻo nickel kiʻekiʻe e hana i ka 304 non-magnetic a hāʻawi iā ia i ke kūpaʻa corrosion maikaʻi loa. Hoʻololi ʻia kēia mau ʻokoʻa i ka hoʻololi ʻana i ke kumukūʻai, ka ikaika, a me ka hana corrosion. 410 kila kila vs 304

Hoʻohālikelike Kūʻai Kūʻai

Laulaha, 410 Ke kila kila ʻoi aku ka liʻiliʻi o ke kumukūʻai ma mua o 304. No ka laʻana, nā kumukūʻai mākeke (ma kahi o 2024) kau i 410 a puni$2,100 no ka metric tona a me 304 a puni $3,500 no ke tona. ʻO ke kumu kūʻai kiʻekiʻe o 304 ke kumu nui mai kāna ʻike nickel (ʻo ka nickel kahi mea hoʻohui waiwai nui). ʻOiaʻiʻo, loli nā kumukūʻai maka, no laila pono nā mea kūʻai aku e hōʻoia i nā huaʻōlelo o kēia manawa. Akā ma ke ʻano he lula, hiki iā 410 ke mālama i kekahi mau tausani kālā no ka ton i hoʻohālikelike ʻia me 304 i nā kūʻai nui.

ʻAno Hoʻohālikelike: Martensitic vs. Austenitic

410 Kuhiliʻole (Martensitic) - He kila kila kila 400-series me kahi 12% chromium a aneane ʻaʻohe nickel. Loaʻa iā ia ke kino-centered cubic (BCC) structure, ka mea e hana ai i ka magnetic a hiki i ka paʻakikī ma ka mālama ʻana i ka wela. ʻIke ʻia nā kila Martensitic no ka ikaika kiʻekiʻe a hoʻopaʻa i ke kūpaʻa i ka wā i huhū ʻia.
304 ʻAi ʻole (Austenitic) – He kila kila kila 300-series me ka 18–20% chromium a me 8–11% nickel. Loaʻa iā ia kahi ʻano aniani cubic alo-centered (FCC) a he non-magnetic. Loaʻa i nā kila Austenitic ka nickel kiʻekiʻe, kahi e hoʻonui ai i ka pale ʻana i ka corrosion. ʻAʻole hiki iā lākou ke hoʻopaʻakikī ʻia e ka mālama wela (ma ka hana anu wale nō) akā hāʻawi i ka paʻakikī maikaʻi loa a me ke ʻano.

ʻO kēia mau ʻokoʻa hoʻohālikelike, ʻoi aku ka paʻakikī a me ka ikaika o 410 (ke mālama ʻia ka wela), ʻoiai ʻo 304 ʻoi aku ka ductile a me ka corrosion-resistant.

Laulā noi a me ka hana

ʻO 410 ka ikaika kiʻekiʻe a me ka paʻakikī o ke kila kila kila i kūpono ia no nā noi pale ʻaʻahu a haʻahaʻa kiʻekiʻe. Hoʻohana maʻamau nā ʻoki ʻoki, nā ʻūhā, nā pūnāwai, nā mea hoʻopaʻa, nā ʻauʻau pamu, a me nā ʻāpana valve - nā mea e pono ai ka lōʻihi a me ke kū'ē i ka hopena. Hiki i ka 410 ke ʻae i nā mahana kiʻekiʻe, akā kūpono wale nō kona kūpaʻa ʻana i ka corrosion: hiki i nā ʻakika ikaika, chlorides, a i ʻole ka maʻa mau ke kumu i ka ʻōpala a i ʻole ka pohā i ka 410. Ua kaupalena ʻia kāna hana ma nā wela kiʻekiʻe a haʻahaʻa loa.

ʻO ka ʻokoʻa, ʻoi aku ka maikaʻi o 304 kila kila ma nā wahi corrosive, pulu, a maʻemaʻe paha. ʻO kāna 18-20% chromium a me 8-11% nickel e hana i kahi kiʻiʻoniʻoni passive oxide e kūʻē i ka rust a me ka oxidation. Hoʻohana nui ʻia ka 304 ma ka hana meaʻai, nā lāʻau lapaʻau, nā lako kīhini, a me nā mea kemika. Hiki iā ia ke hana ma nā mahana cryogenic ʻelua a me nā wela haʻahaʻa kiʻekiʻe (a hiki i ~800 °C) me ka nalowale ʻole o ka ikaika. ʻOi aku ka maʻalahi o ka weld a me ke ʻano: 304 i manaʻo ʻia ʻoi aku ka weldable a me ka ductile ma mua o 410.

Nā hiʻohiʻona hoʻohana

Mea ʻoki a me nā mea hana: ʻO ka paʻakikī o 410 ka mea kūpono no nā pahi pahi, ʻoki, a me nā mea hana ʻoki kaumaha. (Inā makemake ʻia ka pale ʻana i ka corrosion ma ka papa ʻaina, hiki ke hoʻohana ʻia nā māka austenitic e like me 304 a i ʻole 316.)

ʻO ka lumi kuke a me nā lako meaʻai: ʻOi ʻia ka 304 no nā pūnāwai, nā mea kuke, a me nā ʻaoʻao pili i ka meaʻai ma muli o kona kūpaʻa ʻana i ka ʻino a me ka ʻike palekana meaʻai.aoxingmetal.comunifiedalloys.com. No ka laʻana, hoʻohana ʻia ʻo 304 i ka paipu a me nā pahu i nā mea kanu meaʻai, akā hiki ke hoʻohana ʻia ʻo 410 no nā lima a i ʻole nā papa waho i pili ʻole me ka meaʻai.

Nā mea paʻa a me nā lako mīkini: Hoʻohana pinepine ʻia nā bolts, nā nati, nā ʻili, a me nā bushings i 410azom.com e mālama i ke kumukūʻai me ka hāʻawi ʻana i ka ikaika maikaʻi. Pēlā nō, hiki ke hoʻohana i ka 410 i nā lāʻau pāpaʻi a i ʻole nā ʻōpuʻu valve i nā wahi ʻoluʻolu.

Mea Kimia, Aila, a me Kai: ʻO 304 (a i ʻole nā mea hoʻohui kiʻekiʻe aʻe) ka mea e kū ai ka waika, wai paʻakai, a i ʻole nā kūlana koʻikoʻi ʻē aʻe. Hoʻohana maʻamau nā pahu, nā mea hoʻololi wela, a me nā paipu i loko o nā mea kanu kemika a i ʻole kaiapuni kai i ka 304. ʻAʻole hoʻohana ʻia ʻo Martensitic 410 i kēia mau kūlana koʻikoʻi.

Nā Laʻana Hoʻohana Huahana Maoli

I ka hoʻomaʻamaʻa, hoʻohui pinepine nā mea hana i nā māka e hoʻonui i ke kumukūʻai a me ka hana. No ka laʻana, hiki ke hoʻohana i kahi ipu wela uila 304 kila kila no ka ipu kuke o loko (no ka pale ʻana i ka meaʻai a me ka ʻōpala) a 410 kila kila no ka pahu o waho (no ka ikaika a me ke kumu kūʻai haʻahaʻa). Pēlā nō, hoʻohana maʻamau nā pahi kīhini i ka 410 no ka maka, aʻo nā poho a me nā faucets i hana ʻia i 304 e pale aku i ka ʻino wai. I nā mea hana hale, hiki ke hoʻohana ʻia ka 410 no nā papa o loko a i ʻole nā brackets, akā ʻo nā panela a me nā ʻili i ʻike ʻia i ka makū he 304.

Ka hopena a me ka ʻōlelo aʻoaʻo koho mea

ʻO ke koho ʻana ma waena o 410 a me 304 e pili ana i nā mea nui o ka noi. Laulaha:

410 kila kila: Hāʻawi ikaika, paakiki, a me ke kumukuai haahaa. He kūpono ia no nā ʻāpana pale ʻaʻahu a me nā kaiapuni mālie. ʻO kona mau ʻaoʻao haʻahaʻa, ʻo ia ke kūpaʻa corrosion haʻahaʻa (hiki iā ia ke ʻōpala i nā kūlana koʻikoʻi) a ʻoi aku ka paʻakikī o ka mīkini (410 ka hana-paʻakikī).
304 kila kila: Hāʻawi ʻoi aku ka maikaʻi o ka corrosion a me ka paʻakikī. ʻO ia ke koho palekana no ka pulu, acidic, a i ʻole nā mea maʻemaʻe, a ʻaʻole ia he magnet. ʻO kāna mau hemahema koina kiekie (ma muli o ka nickel) a haʻahaʻa loa ka paʻakikī (ʻaʻohe hoʻopaʻapaʻa mālama wela).

Pono nā poʻe ʻoihana kūʻai e loiloi i ke kaiapuni a me nā pono mechanical. Inā koʻikoʻi ka pale ʻana i ka corrosion a i ʻole ka maʻemaʻe, 304 ke kumu kūʻai; inā ʻoi aku ka nui o ka lōʻihi o ka mīkini a me ke kumu kūʻai haʻahaʻa, hiki i ka 410 ke lawa. E hōʻoia mau i nā kumukūʻai makeke o kēia manawa (hiki ke hoʻololi i nā kumukūʻai nickel i nā koina 304) a e nīnau i ka ʻikepili mea hoʻolako. Ma ka hoʻohālikelike ʻana i ka pae kila i nā koi kikoʻī, hiki i nā mea kūʻai ke hoʻonui i ka hana a me ke kālā.
