904L Kev Loj Loj Lub Zog Stainless Hlau Phaj Cov Lus Qhia
904L Stainless Hlau Phaj yog lub siab {{1} {{{{{{{{{{{{}}}} muaj xov xwm. Kev nplua nuj nyob hauv npib tsib xee, chromium, thiab tooj liab, thiab kev nyuaj siab} cov phaj corrosion, xws li kev ua yeeb yam, thiab muaj cov tshuaj lom neeg zoo thiab weldability.
Yuav ua li cas 904L steel tiv thaiv corrosion?
Nws yog softer tshaj 316L steel. Qhov sib ntxiv ntawm molybdenum muab nws zoo heev tsis kam rau cov cheeb tsam chloride nres (pitting thiab crevice corrosion) thiab ua kom zoo txo corrosion los ntawm acidic tshuaj. Qhov sib ntxiv ntawm tooj liab, tshwj xeeb, muab cov txiaj ntsig zoo rau cov sulfuric acid ntawm txhua qhov ntau.
904L Kev Loj Loj Lub Zog Stainless Hlau Phaj Cov Lus Qhia
904L alloy (tsis yog n08904) yog super - Austenitic stainless hlau tsim los muab cov kev tiv thaiv ntau yam rau cov txheej txheem ib puag ncig. Kev sib xyaw ntawm cov roj hluav taws xob siab thiab cov kab tsib npib tsib xee, nrog rau kev sib ntxiv ntawm Molybdenum thiab tooj liab, ua kom zoo rau kev ua haujlwm corrosion zoo tshaj plaws.
Nrog nws cov high high all Alloy ntawm 25% Nickel thiab 4.5% Molybdenum, pitting chloside kev ntxhov siab, thiab dav}}}}}}} }l thiab 317l stainless hlau.
904L alloy tau xub tsim kho rau dilute sulfuric ib puag ncig. Nws tseem ua rau pom zoo rau lwm cov inorganic acids, xws li kub phosphoric acid, nrog rau cov organic accic acids.
904L alloy yog yooj yim welded thiab tuaj yeem ua tiav siv cov qauv khoom siv cabrication.

Corrosion Kuj
Cov ntsiab lus siab ntawm alloy cov ntsiab hauv 904L phaj muab cov khoom siv zoo heev corrosion tsis kam.
Ameslikas tau tsim tawm rau kev tawm tsam hauv dilute sulphuric acid, xws li ib qho ntawm cov kua ntxwv zoo li ntawm 0 txog rau cov kua qaub zoo nkauj (xws li phosphoric acid) thiab feem ntau cov organic acids. Txawm li cas los xij, cov kua qaub thiab cov kua qaub acidic muaj cov nplooj lus hauv thaj av hauv 317L, thiab cov xeb tawm tsam ntawm 317L, 317L, thiab 904L yuav tsis txaus.
Lub frectation ntawm cov roj siab feem ntau yuav tsum tau muaj cov khoom siv zoo dua rau 316L lossis txawm tias ntau siv 317LMN. Nyob rau hauv cov siab - kub, concentrated alkaline daws, corrosion tsis yog nyob ntawm cov khoom siv cov ntsiab lus npib tsib xee. Nrog cov ntsiab lus npib tsib xee ntawm 25%, 904L tau muaj pov thawj los ua lwm txoj hauv kev zoo rau cov hlau feem ntau.
Cov hlau uas tsis muaj zog xws li 304L thiab 316L thiab 316L muaj kev cuam tshuam rau cov chloride kev ntxhov siab corrosion (SSC) nyob rau qee yam. Cov ntsiab lus nickel thiab molybdenum cov ntsiab lus nce SSC tiv taus. Thiaj li, siab {{4 4}} kev ua yeeb yam Austenitic Stainless hlau xws li 904L daim ntawv pom kev tshwj xeeb SSC tsis kam. Lub rooj nyob rau hauv lub kaum sab xis sab sauv qhia SSC tsis kam nyob hauv cov tshuaj chloride hauv qab ntawm kev sib cais. High - Kev Ua Haujlwm Austenitic thiab Duplex Stainless Hlau Tseem Ceeb Tshaj Outperform 316L.
