S32750 uamea uamea fa'asu'amea
Folasaga o oloa
Super Duplex stainless e pei o S32750, o se microstructure fefiloi o austenite ma ferrite (50/50) lea ua faaleleia atili le malosi i luga o ferritic ma austenitic uamea togi. O le eseesega autu o le Super Duplex o loʻo i ai le maualuga o le molybdenum ma le chromium mea e maua ai mea e sili atu. ma embrittlement e le sigma, chi ma isi vaega i le maualuga o le vevela.
Alloy 2507 (S32750) e iai foʻi le maualuga o le nitrogen content, lea e le gata ina faʻamalosia ai le faʻavaeina o le austenite ma faʻateleina le malosi, ae faʻatuai foi le faʻavaeina o vaega intermetallic e lava e faʻatagaina ai le gaosiga ma le fausiaina o le duplex grade.
O le vasega o loʻo faʻaalia i le lelei tele o le chloride corrosion resistance, faʻapipiʻiina ma le maualuga tele o le malosi faʻainisinia. E fa'apitoa mo le fa'aoga i totonu o si'osi'omaga fa'amalosi e pei ole suasami fa'amafana chlorinated ma ala fa'asalalau o lo'o iai le chloride acid.
Alloy 2507 (S32750) uiga e fa'apea:
● Tete'e sili atu i fa'amamafa ta'eta'e (SCC) i chloride-tauave siosiomaga
● E sili ona tetee atu i le pala ma le gaogao
● Teteʻe maualuga i le pala lautele
● Malosi fa'ainisinia maualuga
● Mea faʻaletino e ofoina atu le lelei o le mamanu
● Teteʻe maualuga i le pala ma le vaivai vaivai
● Lelei faʻapipiʻi
S32750 ua mamanuina mo talosaga manaʻomia e manaʻomia ai le malosi faʻapitoa ma le faʻafefeteina, lea e maua i totonu.fa'agasologa o vaila'au, petrochemical, ma mea faigaluega o le sami. E fa'aaoga lautele i su'esu'ega suau'u ma kesi i fafo / gaosiga ma i fa'afesuia'i vevela ile gaosiga ole petrochemical/kemikolo. O le vasega e fetaui lelei mo le fa'aogaina o le hydraulic ma meafaigāluega i si'osi'omaga o le gataifale.
