  ʻOi aku ka haʻahaʻa o ka thermal centaltivity ma mua o ka carel carbon, wela wela mai nā ulding unding dissipates; Hoʻopili kēia i nā kaʻina hana a me nā hana hoʻokomo.

ʻO ka hanaʻo Cenogongenic:

• ʻO nā mea hoʻokūkū Austeditic ret i loaʻa i ka paʻakikī ma nā haʻahaʻa haʻahaʻa loa a me nā mea maʻamau i hoʻohanaʻia ma nā kūlana cryogen.

8. Nā pōmaikaʻi o 300-Series Austenitic Stainless Steel

Nā hiʻohiʻona loea o 300-series Austenitic staelless-ʻO ka paleʻana i ke kū'ēʻana, ʻO nā micsstruc microstrutic, maikaʻi loa, a me ka nawaliwali-unuhi i loko Pono, pōmaikaʻi pono No nā mea hana, Nā mea hoʻohana-hoʻohana, a me nāʻoihana.

ʻO ka mālama haʻahaʻa a me ke ola holoʻokoʻa

• Ke kū'ē neiʻo Corrosionion: ʻO ka paleʻana i ka interent i ka corrosion e hoʻopau i ka pono no ka pena kiʻi, Wehe, a iʻole ka hoʻomaʻemaʻe pinepineʻana.
  ʻo kahi laʻana, 316L nā mea hana many e like me nā mea holo moku hiki ke lilo i hope 20-30 mau makahiki ma ka paʻakai paʻakai, ua hoʻohālikelikeʻia 5-10 mau makahiki no ke kila carbon coated.
• Nā mālama kālā: Hoʻemiʻia ka hopena o ka neʻeʻana a me ka hana hana mālama i nā mālama nui.
  ʻO nā meaʻai hana meaʻai e hoʻohana ai 304 Nā Pono Hana Hōʻikeʻia i 50% ʻO nā kumukūʻai haʻahaʻa haʻahaʻa hoʻohālikelikeʻia me nā mea kila kila carbon.

Intertility ma waena o nā noi

• Nā mea waiwai nui: He papa hoʻokahi e like me 304 hiki ke lawelawe i nāʻoihana he nui-ʻO ka ho'ōlaʻana i ka meaʻai (sinks, kaniulail), Biikona (kumamalima, Handrail), a nā leka uila (nā pā)-Simpliplinging i nā kaulahao a me ka hōʻemiʻana i nā koi waiwai.
• Papa hana papa: ʻO nā māka kūikawā i hoʻonuiʻia:

Kumukūʻai-kūpono

• Hoʻolālā kūleʻa kaulike vs. Kālā: 304 maʻamau maʻamau 20-30% eʻoi aku ka maikaʻi ma mua o nā alloys kūikawā (E.g., HadELy C276) ʻOiai e hoʻokō ana 80% o nā pono noi noi.
  ʻo kahi laʻana, 304L piping kumukūʻai $ 2- $ 4 i kēlā me kēia wāwae, ma waena o $ 10- $ 15 i kēlā me kēia wāwae no 6% Nā MolyBdelu Alloys.
• Uku haʻahaʻa haʻahaʻa: ʻO ka normability maikaʻi a me ka ulia e hōʻemi ai i nā hana fabrication a me ka manawa hana.
  Hōʻike nā mea hana ≈30% wikiwiki wikiwiki na 304 Hoʻokomoʻia nā pahu kila Strienless i hoʻohālikelikeʻia me nā helu ferritic.

ʻO ka noʻonoʻo a me Recyclability

• Recylability High: 300-sericant sisinless steel 100% recyclable, me ka 90% of scrap reed i ka hana hou.
  Kiʻi houʻia 304 Mālama i nā mea like me nā waiwai a me nā corrosioni a me nā waiwai corrosioni, Ka hoʻohiheʻana Nā Emisbons emissions e ~ 50%.
• FILLTEDED MODESPAN: Ola lōʻihi (20-50 makahiki) ho'ēmi i nā alapine e hoʻololi ai, ʻO ka hopena o ke kaiāulu holoʻokoʻa.
  ʻo kahi laʻana, 304 ke kūkuluʻana i nā lauoho e koi pinepineʻole no ka hoʻololiʻana no 40+ mau makahiki, ua hoʻohālikelikeʻia 10-15 mau makahiki no aluminim.

Hilinaʻi ma nāʻano nui

• Cryogicication: Nā Kaumaka 304 a 316 Mālama i ka paʻakikī ma -270 ° C, e hana ana iā lākou no Lng mālama, ʻO nā pahu pahu pahu, a me nā palapala noi e nā cristogen kahi i hikiʻole ai ke pale i ka catastrophic.
• ʻO ka nui o ka nohoʻana:310 e hana mau ana i ka hana 1150° C, hōʻoia i ka hilinaʻi i loko nā lako hanaʻoihana a me nā lako hana wela.
  Nā mea hoʻololi 5-10 mau makahiki no ka 310 Nā'āpana huluhulu, kūwaho 1-2 mau makahiki no ke kila carbon.

9. PAHUI, ʻO nā hana hana a me nā hana hoʻoikaika kaʻa

• Pitting and crevice corrosionion ma chrloudes: E hoʻomaʻamaʻaʻia ma ke kohoʻana i nā helu molybden (316), e wehewehe ana i nā mea kiʻekiʻe a iʻole nā ​​mea kiloki a iʻole duplex no ka hoʻolahaʻana i ka hoʻolaha, a iʻole e hoʻopili ana i nā pale pale pale.
• ʻO ke kūleʻaʻana o ke kalaʻana: Hoʻemi i nā kaumaha kūlohelohe o Tensile, kaohi a me ke aniani, a iʻole e koho i nā mea hou o SCC-resistant.
• Hana paʻakikī a me ka mancinability: E hoʻohana i nā mea hana kūpono a me nā'āpana kūpono; E noʻonoʻo i kaʻaeʻana a iʻole ka hoʻohanaʻana i nā variants manuahi manuahi inā he koʻikoʻi ka macinability.
