S32750 Fa'alava Uamea Fa'alava

Fa'amatalaga Puupuu:

Alloy 2507, faʻatasi ai ma le UNS numera S32750, o se uʻamea lua-vaega e faʻavae i luga o le uʻamea-chromium-nickel system faʻatasi ai ma se fausaga faʻafefiloi e tusa ma le tutusa tutusa o austenite ma ferrite. Ona o le paleni vaega lua, Alloy 2507 faʻaalia le teteʻe sili atu i le pala e pei o austenitic uʻamea uʻamea ma elemene faʻafefiloi tutusa. E le gata i lea, o loʻo i ai le malosi sili atu ma le malosi e maua ai faʻapea foʻi ma le sili atu o le chloride SCC teteʻe nai lo ona austenitic faʻataʻitaʻiga aʻo tumau pea le malosi sili atu nai lo le ferritic counterparts.

Faailoga o oloa

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 le mea e sili atu.

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 faʻainisinia 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.
