2205 uamea uamea 4*1mm capillary coiled tubing
O nisi o faʻaoga masani o le uʻamea uʻamea lua vasega 2205 o loʻo lisiina i lalo:
- Su'ega suau'u ma kesi
- Mea faigaluega gaosi
- Felauaiga, teuina, ma le gaosiga o vailaʻau
- Ole maualuga ole chloride ma le gataifale

Vaega o le Duplex Ss 2205
2205 uamea uamea 4*1mm capillary coiled tubing
Duplex Stainless Steel 2205 Fa'atusatusa i le 316L ma le 317L austenitic u'amea u'amea, 2205 e sili atu i le anti-pitting ma crevice corrosion teteʻe.E maualuga le corrosion tete'e.Pe a faʻatusatusa i le austenite, o lona faʻalauteleina o le vevela e maualalo, o le faʻauluina o le vevela e maualuga atu.
Duplex Stainless Steel 2205 e faaluaina le malosi compressive o austenitic uʻamea uʻamea, faʻatagaina tagata mamanu e faʻaitiitia lo latou mamafa pe a faʻatusatusa i le 316L ma le 317L.O le 2205 alloy e sili ona talafeagai mo le faʻaaogaina i le -50 ° F / + 600 ° F le vevela ma e mafai ona faʻaaogaina mo le maualalo o le vevela i lalo o tapulaʻa ogaoga (aemaise mo le fausiaina o le uelo).
Le fa'afefeteina o le 2205 Duplex Stainless Steel
2205 uamea uamea 4*1mm capillary coiled tubing
- Fa'amea tutusa, O le fa'afefeteina o le duplex stainless steel 2205 e sili atu nai lo le 316L ma le 317L i le tele o siosiomaga ona o le chromium (22%), molybdenum (3%), ma le nitrogen (0.18%).
Fa'apitonu'u anti-corrosion, O mea o lo'o i totonu o le chromium, molybdenum, ma le nitrogen i le duplex stainless steel 2205 e matua fa'asalaina ai le pitting ma le ga'o i vaifofo oxidizing ma acidic. - Anti-stress corrosion, O le 2205 duplex structure of stainless steel e fesoasoani e faʻaleleia atili ai le teteʻe atu i le faʻalavelave faʻafefe o le uʻamea.I se vevela faapitoa, i lalo o tulaga o le vevesi, okesene, ma chloride, chloride mamafa corrosion e tupu i austenitic stainless steel.Ona o nei tulaga e le faigofie ona pulea, o le faʻaaogaina o le 304L, 316L, ma le 317L e faʻatapulaʻaina i lenei tulaga.
- Anti-corrosion vaivai, Lua-vaega uʻamea 2205 malosi maualuga ma corrosion teteʻe i le corrosion tetee maualuga malosi vaivai vaivai.O le gaosiga o meafaigaluega e faigofie ona afaina i siosiomaga ma le utaina o taamilosaga, ma o le duplex stainless steel 2205 foliga e fetaui lelei mo ia talosaga.
Metallography e uiga i le Duplex Ss 2205 uns s31803
O le vailaʻau vailaʻau o le 2205 duplex uamea e maua ai le microstructure manaʻomia o le 50 ϫ / 50 i le maeʻa ai o le 1900 / 1922 ° F (1040 °C / 1080 ° C) vaifofo malulu.Afai o le vevela o togafitiga e maualuga atu nai lo le 2000 ° F, e mafai ona oʻo atu ai i le faʻateleina o le faʻaogaina o le ferrite.E pei o isi u'amea u'amea lua, 2205 u'amea e mafai ona fa'afefe i le vaeluaga o timuga.
O le vaega intermetallic precipitates i le va o le 1300 ° F ma le 1800 ° F ma precipitates vave i le 1600 ° F. O le mea lea, e tatau ona tatou suʻeina 2205, ina ia mautinoa e leai se vaega intermetallic, o le suʻega suʻega ASTM A 923.
