u'amea u'amea ferritic
Chromium 15% i le 30%. O lona teteʻe o le corrosion, faigata ma le weldability faateleina i le faateleina o le chromium anotusi, ma lona tetee atu i le chloride stress corrosion e sili atu nai lo isi ituaiga o uʻamea uʻamea, e pei o le Crl7, Cr17Mo2Ti, Cr25, Cr25Mo3Ti, Cr28, ma isi. E masani ona faʻaaogaina i fausaga faʻasaʻo faʻamaʻi ma maualalo le faʻalavelave ma e pei o le sila-antioxidation. O lenei ituaiga o uamea e mafai ona tetee atu i le pala o le siosiomaga, nitric acid ma le masima fofo, ma ei ai uiga o le maualuga maualuga o le vevela o le faʻamaʻiina o le faʻamaʻiina ma le faʻalauteleina o le vevela. E faʻaaogaina i le nitric acid ma meaʻai fale gaosi meaʻai, ma e mafai foi ona faʻaaogaina e fai ai vaega e galue i le maualuga o le vevela, e pei o vaega turbine gas, ma isi.

Austenitic uamea uamea
O loʻo aofia ai le sili atu i le 18% chromium, ma e aofia ai foʻi le 8% nickel ma se vaega itiiti o le molybdenum, titanium, nitrogen ma isi elemene. Lelei atoa le faatinoga, e tetee i le pala e ala o faasalalauga eseese. O togi masani o austenitic stainless steel o 1Cr18Ni9, 0Cr19Ni9 ma isi. O le Wc o le 0Cr19Ni9 uamea e itiiti ifo i le 0.08%, ma o le numera uʻamea ua faailogaina o le "0". O lenei ituaiga o uamea o loʻo i ai se aofaiga tele o Ni ma Cr, lea e faʻaogaina ai le uamea austenitic i le vevela o le potu. O lenei ituaiga o uamea e lelei le palasitisi, faigata, faʻafefe, faʻafefeteina ma le le maneta poʻo le vaivai ma le mumu e faʻaogaina ai le faʻaogaina o mea faʻamaneta. mea e fa'asa'o vai, e pei o atigi pusa ma meafaigaluega linings, pipelines, nitric acid-tetee meafaigaluega vaega, ma e mafai foi ona faaaoga e avea ma mea autu o uamea uamea uamea uamea masani faaaogaina fofo fofo, o lona uiga, ua vevela le uamea i le 1050-1150 ° C, ona maua ai lea o le ea-cooled ea.

Austenitic-ferritic duplex uamea uamea
E i ai le lelei o austenitic ma ferritic stainless steels, ma e superplasticity. Austenite ma ferrite tala taitasi mo le tusa ma le afa o le sila stainless. I le tulaga o le maualalo carbon anotusi, o le anotusi o le chromium (Cr) o le 18% ~ 28%, ma le anotusi o le nickel (Ni) o le 3% ~ 10%. O nisi uamea o loʻo iai foʻi elemene faʻafefiloi e pei o Mo, Cu, Si, Nb, Ti, ma N. O lenei ituaiga uʻamea e iai uiga o austenitic ma ferritic stainless steels. Pe a faatusatusa i le ferrite, e maualuga atu le palasitisi ma le faigata, leai se vevela vevela brittleness, matua faaleleia intergranular corrosion teteʻe ma le uʻamea faatinoga, aʻo tausia le uʻamea O le tino uamea uamea e brittle i le 475 ° C, e maualuga conductivity vevela, ma ei ai uiga o le superplasticity. Fa'atusatusa i le austenitic stainless steel, e maualuga lona malosi ma fa'aleleia atili le tete'e i intergranular corrosion ma chloride stress corrosion. Duplex u'amea u'amea e sili ona lelei tete'e pitting corrosion ma o se nickel-sefe u'amea uamea.

Ua maaa le timuga uamea
O le matrix o le austenite poʻo le martensite, ma o le faʻaaogaina masani o le faʻaogaina o le faʻamaʻaina o timuga uamea 04Cr13Ni8Mo2Al ma isi. Ose u'amea u'amea e mafai ona fa'ama'a'aina (fa'amalosia) e ala i le fa'ama'a'aina o timuga (fa'aigoa fo'i o le fa'ama'a'a tausaga).

Martensitic uamea uamea
Malosi maualuga, ae le lelei palasitisi ma weldability. O togi e masani ona faʻaaogaina o martensitic stainless steel o 1Cr13, 3Cr13, ma isi, ona o le maualuga o le carbon content, e maualuga le malosi, faigata ma le ofuina o le teteʻe, ae o le faʻamaʻiina o le corrosion e laʻititi le leaga, ma e faʻaaogaina mo mea faʻainisinia maualuga ma le faʻaleagaina. O nisi o vaega lautele e manaʻomia, e pei o puna, vaʻa afi afi, vaʻa lolomi hydraulic, ma isi. O lenei ituaiga uʻamea e faʻaaogaina pe a uma ona tineia ma faʻafefe. E mana'omia le su'iina pe a uma ona fa'amea ma fa'ailoga.
