Meatotino Lautele
Alloy 2205 duplex plate u'amea u'amea o se 22% Chromium, 3% Molybdenum, 5-6% Nickel nitrogen alloyed duplex stainless steel ipu ma le maualuga lautele, localized ma popolega corrosion teteʻe meatotino i le faaopoopo atu i le malosi maualuga ma le aafiaga sili ona faigata.
2205 uamea uamea vili paipa
Alloy 2205 duplex plate u'amea u'amea maua pitting ma clevice corrosion teteʻe sili atu i le 316L po o le 317L austenitic uʻamea uʻamea i le toetoe lava uma ala pala.O lo'o i ai fo'i le maualuga o le pala ma le tafia o mea vaivai fa'apea fo'i le fa'alauteleina o le vevela ma maualuga atu le fa'auluina o le vevela nai lo le austenitic.
O le malosi e maua ai e tusa ma le faaluaina o austenitic stainless steels.Ole mea lea e mafai ai e se tagata mamanu ona fa'asaoina le mamafa ma fa'atauva'a ai le u'amea pe a fa'atusatusa ile 316L po'o le 317L.
2205 uamea uamea vili paipa
Alloy 2205 duplex ipu uamea e sili ona talafeagai mo talosaga e aofia ai le -50 ° F / + 600 ° F vevela laina.O le vevela i fafo atu o lenei va'aiga e mafai ona iloiloina ae mana'omia ni tapula'a, aemaise lava mo fausaga uelo.
Tete'e a'e
A'oa'i Lautele
Ona o le maualuga o le chromium (22%), molybdenum (3%), ma le nitrogen (0.18%) o loʻo i totonu, o mea e teteʻe ai le corrosion o le 2205 duplex stainless steel plate e sili atu nai lo le 316L poʻo le 317L i le tele o siosiomaga.
Fa'alotoifale Tete'e
O le chromium, molybdenum, ma le nitrogen i le 2205 duplex stainless steel plate e maua ai foʻi le teteʻe lelei i le pitting ma le gaʻo e oʻo lava i vaifofo faʻamaʻi ma faʻamaʻi.
Isocorrosion Curves 4 mpy (0.1 mm/yr), i le vaifofo sulfuric acid o lo'o iai le 2000 ppm
Fa'amamafa Tete'e a'e
O le fa'apipi'i microstructure ua iloa e fa'aleleia atili ai le fa'amamafaina o fa'ama'i fa'a'a'a'esega o u'amea u'amea.
Ole fa'amamafa ole chloride e mafai ona tupu ile u'amea austenitic u'amea pe a iai tulaga mana'omia o le vevela, fa'amamafa, okesene, ma chlorides.Talu ai o nei tulaga e le faigofie ona faʻatonutonuina, o le taʻe aʻe o le mamafa e masani ona avea ma pa puipui i le faʻaaogaina o le 304L, 316L, poʻo le 317L.

Tete'e ole vaivai ole pala
Alloy 2205 duplex stainless steel plate e tuʻufaʻatasia le malosi maualuga ma le faʻafefe maualuga e maua ai le malosi vaivai vaivai.Talosaga e fa'aogaina ai masini e fa'atatau i se si'osi'omaga e pala ma fa'aoso fa'ata'amilomilo e mafai ona fa'amanuiaina mai meatotino o le 2205 duplex plate stainless steel.
