INCOLOY 825 (UNS N08825 / NS142)
Fa'atatauga
Alloy 825 o se austenitic nickel-iron-chromium alloy ua faʻamatalaina foi i faʻaopoopoga o le molybdenum, kopa ma le titanium. Na fa'atupuina e tu'uina atu ai le tete'e fa'apitoa i le tele o si'osi'omaga pala, fa'ama'i fa'ama'i ma fa'aitiitia.
Alloy 825 na fa'atupuina e maua ai le tete'e fa'apitoa i le tele o si'osi'omaga pala, fa'ama'i fa'ama'i ma fa'aitiitia. Faatasi ai ma le nickel content range i le va o le 38%-46%, o lenei vasega o loʻo faʻaalia le faʻaalia o le teteʻe atu i le faʻalavelave faʻafefe (SCC) faʻaosoina e chlorides ma alkalis. Ole mea ole nickel e lava mo le tetee atu ile chloride-ion stress-corrosion ta'e. O le nickel, faʻatasi ma le molybdenum ma le kopa, e tuʻuina atu ai foʻi le tetee mataʻina i le faʻaitiitia o siosiomaga e pei o mea o loʻo i ai sulfuric ma phosphoric acids.
Ole mea ole chromium ma le molybdenum e maua ai fo'i le fa'asao lelei i totonu o si'osi'omaga uma se'i vagana ai vaifofo chloride malosi fa'ama'i. Faʻaaogaina e avea o se mea aoga i le tele o siʻosiʻomaga faʻagasologa, o le alloy 825 o loʻo tausia lelei mea faʻainisinia mai le vevela cryogenic e oʻo atu i le 1,000 ° F.
O le fa'aopoopoina o le titanium e fa'amautu ai le Alloy 825 e fa'asagatau i le fa'alogoina i le tulaga fa'apipi'i e fa'asalaina ai le u'amea i osofa'iga fa'ava-o-malo pe a uma ona fa'aalia i le vevela i se va'aiga e fa'afefe ai u'amea e le mautu. O le gaosiga o le Alloy 825 e masani lava o u'amea fa'avae nickel, fa'atasi ai ma mea e faigofie ona fa'apipi'iina ma fa'afefeteina e ala eseese.
O lenei mea e sili ona lelei le fa'aogaina, e masani lava o u'amea fa'avae nickel, fa'ataga le mea e punou i radii la'ititi. E le masani ona mana'omia le fa'amuta pe a uma ona punou.
E talitutusa ma le u'amea 800 ae ua fa'aleleia atili le tete'e atu i le vai. E matua'i lelei le tete'e atu i le fa'aitiitia ma le fa'ama'i fa'ama'i, i le fa'amamafa o le fa'amamafa, ma le osofa'iga fa'apitonu'u e pei o le pitting ma le ga'o. Alloy 825 e sili ona tetee i sulfuric ma phosphoric acids. O lenei u'amea u'amea nickel o lo'o fa'aaogaina mo le gaosiga o vaila'au, mea e fa'aleagaina ai le fa'aleagaina, paipa lelei o le suau'u ma le kesi, toe gaosia o suau'u faaniukilia, gaosiga o vaila'au, ma meafaigaluega piki.
