Dachang moni 304L fa'atau paipa uamea
O le American Iron and Steel Institute e faʻaaogaina numera e tolu e faʻailoga ai tulaga eseese
E foliga vaivai. O lea:
① Austenitic stainless steel o loʻo faʻaalia i numera o le 200 ma le 300 faasologa,
②Ferritic ma martensitic uamea uamea o loʻo faʻatusalia e 400 numera faasologa. Mo se faʻataʻitaʻiga, o nisi o uʻamea austenitic sili ona taatele
Faailoga 201, 304L, 316 ma le 310,
③ Ferritic uamea uamea ua faailogaina i le 430 ma le 446, ma martensitic uamea ua faailogaina i le 410, 420 ma le 440C.
Manatua, duplex (austenite ferrite),
④ u'amea u'amea, timu fa'ama'a'aina u'amea u'amea ma u'amea mea i lalo ifo o le 50% masani fa'aaoga igoa pateni po'o igoa tau fefa'ataua'iga.
① Fa'ailoga fa'ava-o-malo elemene elemene ma fa'ailoga a le atunu'u o lo'o fa'aaogaina e fai ma sui o vaila'au, ma o mata'itusi Arapi e fa'aaogaina e fai ma sui o mea e aofia ai:
Mo se faʻataʻitaʻiga: Saina, Rusia 12CrNi3A
②Fa'aoga numera numera fa'amau e fa'atusa ai fa'asologa u'amea po'o numera; Mo se faʻataʻitaʻiga, o le Iunaite Setete, Iapani, 300 series, 400 series ma 200 series.
③ O le numera fa'asologa e aofia ai mataitusi Latina ma le fa'atonuga, lea e na'o le fa'amoemoega.
Fa'aoga, Pinyin Saina, u'amea tatala tapuni: P, u'amea uamea: F, u'amea mate: B, vasega a uamea: A, T8: te8

◆ uamea fusifusia ma uamea tautotogo, e pei o le 20CrMnTi 60simn, (C anotusi o loʻo faʻaalia i le sefulu afe)
◆ u'amea u'amea ma u'amea meafaigaluega uamea (C anotusi o loʻo faʻaalia i afe), pei ole 1 afe ole 1Cr18Ni9 (ie
0.1% C), C stainless C ≤ 0.08%, pei ole 0Cr18Ni9, ultra-maualalo carbon C ≤ 0.03%, pei ole 0cr17ni13mo
O le mamafa ile mita ole 304L paipa u'amea u'amea = pito i fafo - mafiafia puipui x mafiafia puipui x0.02491
Elemene anotusi o le 304L paipa uamea u'amea c ≤ 0.03, ni8.00 ~ 12.00, cr18.00 ~ 20.00, Mn <= 2.0, Si <= 1.0, s <= 0.030, P <= 0.035.
304L paipa uamea u'amea 18cr-8ni-maualalo carbon pei Low-C 304 uamea, lona tetee corrosion e tutusa ma 304 uʻamea i le lautele, ae o lona tuaoi saito tetee corrosion e sili ona lelei pe a uma le uelo po o le toomaga popole; E mafai fo'i ona fa'atumauina lelei le fa'afefeteina e aunoa ma le vevela, ma le vevela o le tautua - 196 ℃ ~ 800 ℃. E faʻaaogaina i masini i fafo i vailaʻau, koale ma suauʻu faʻapitoa e manaʻomia maualuga mo le faʻafefeteina o tuaoi o saito, vaega vevela o mea fau fale ma vaega e faigata ile togafitiga vevela.
Fa'amoemoega: fa'aaogaina mo le fa'ainisinia vai inu sa'o ma isi felauaiga fa'afefe ma mana'oga maualuga
Autu autu: ola umi auaunaga; Fa'aletonu maualalo ma le tafe o le vai; E lelei le tulaga lelei o le suavai, ma e leai ni mea leaga o le a fa'afefe i totonu o le vai; O le puipui i totonu o le paipa e lamolemole ma e maualalo le faʻafefe o le vai; Faʻatinoga tau maualuga, ola tautua e oʻo atu i le 100 tausaga, leai se tausiga ma tau maualalo; E mafai ona tatalia le maualuga o le tafe o le vai e sili atu nai lo le 30m / S; Fa'ata'atia paipa ma foliga matagofie.
Fa'aoga: susu ma mea'ai alamanuia, alamanuia pharmaceutical, alamanuia e iai manaoga faapitoa i totonu.
Fa'agasologa fa'agasologa: fa'avasegaina o lo'o fa'aulufaleina i totonu, togafitiga fa'ato'a mautu, fa'alelei eletise eletise i totonu.
Fa'atinoga fa'atinoga: o le pito i totonu roughness Ra e sili atu nai lo le 0.2, o le puipui tautau o totoe e la'ititi, faigofie ona fa'amama, puipuia le tuputupu a'e siama, fa'alelei electrolytic ei ai aafiaga passivation, ma le puipui i totonu e lelei le puipuiga.
Metotia o su'ega: fa'ata'atia, fa'a'umi'umi fa'amafola, fa'ata'amilo fa'asaga, su'ega hydrostatic po'o le su'esu'eina o mea sese o lo'o i ai nei, su'ega mea tau masini, su'ega gaogao i totonu.
