Corrosion Kuj
Chloride corrosion tsis kam ntawm astm A240 ss 317l
Cov ntsiab lus molybdenum siab ua rau nws ua tau zoo hauv cov chloride ion ib puag ncig (pren) yog qhov haum rau ntug dej platform thiab cov cuab yeej tshuaj desalination.
Acidic nruab nrab tiv taus ntawmDIN 1.4438 PHAJ
Nws muaj qhov ua tau zoo heev rau cov xov xwm uas muaj cov sulphoric acid, thiab ua haujlwm tau cov kua qaub, thiab tseem muaj zog nyob rau hauv 5% sulfuric acid daws (tsawg dua los yog sib npaug rau 49 degree).
Nruab nrab corrosion tsis kam ntawm astm A240 unstral s31703 phaj
Tsawg cov pa roj carbon ua ke nrog daws analing analing txheej txheem ({0}} degree)

Kev kub siab ruaj khov ntawm stainless hlau 317L phaj
SS 317L Cov khoom ua pov thawj zoo heev oxidation tsis kam nyob rau hauv ib puag ncig kub nyob hauv 1600 degree F (li 87 degree F (txog 899 degree).
Lub cev cov khoom ntawm Werkstoff tsis yog 1.4438 kauj
317L cov khoom siv lub cev muaj cov nqi zog 7.98 g / cmÃ, melting point {3}} Cov khoom kub thiab cov khoom siv cua sov thiab cov tshuaj tua hluav taws.
Cov chaw thov ntawm ASME SAA240 hom 317L phaj
Tshuaj thiab Petrochemical:siv los tsim cov tshuaj reactors, tso tsheb tso tsheb rau khoom, cov ntawv luam tawm piping.
Marine Engineering:Cov khoom siv desalination, submarine pipelines thiab nkoj Cheebtsam.
Kev tiv thaiv lub zog thiab ib puag ncig:Flue Gas Desulfurization (FGD) tshuab, lub zog tsim hluav taws xob cog txias thiab tswj cov kuab paug.
Kev kho mob thiab khoom noj:Kev kho deg polished rau ra <{{{{0μm}. 8μm muaj kev tsis muaj menyuam thiab cov khoom siv phais, khoom siv khoom lag luam thiab khoom noj ua khoom.
Txiav thiab tsim ntawmS 317l phaj
Nws raug nquahu kom siv ntshav txiav los yog laser txiav, thiab zam kom tsis txhob muaj cov carbon arc gouging kom tiv thaiv oxidation. Cov txheej txheem nce qib yuav tsum muaj rau kev ua kom txias kom txo qis kev ua haujlwm hnyav.
Vuam ntawm SS317L
Tungsten inert roj vuam (gtaw) lossis hlau inert roj vuam (GMAW) yog qhov kev nyiam. AWS E317L lossis Nickel-based alloy yog pom zoo raws li cov khoom siv cov khoom siv. Cov interlayer kub ntawm tus weld yuav tsum tau tswj hwm hauv qab 60 degree kom ntseeg tau tias cov corrosion tsis kam ntawm Weld.
Kev kho cua sov ntawm S31703 Ntawv
Tshuaj Annaling (1010-1150 degree) tuaj yeem tshem tawm kev ntxhov siab thiab yaj cov carbides, txhim kho cov kev ntxhov siab thiab corrosion tsis kam ntawm cov khoom.
317l stainless hlau phaj sib piv nrog cov ntaub ntawv zoo sib xws
Piv nrog 316L, 317l muaj cov ntsiab lus molybdenum siab dua (}}}}}}}}}}}} {%), tshwj xeeb tshaj yog rau dej hiav txwv thiab acidic ib puag ncig. Piv nrog 317LMN (muaj ntau dua molybdenum thiab nitrogen), 317l muaj tus nqi qis dua thiab me ntsis qis dua siab dua lub zog kub. Hais txog kev lag luam, tus nqi pib ntawm 317L yog hais txog {}}% ntau dua li 50% nyob rau hauv ntau dua 50% nyob rau hauv ntau dua 50% nyob rau hauv ntau dua 50%
