904L stainless hlau yog ib qho tsis-stabilized austenitic stainless hlau nrog cov ntsiab lus qis. Qhov no high alloy stainless hlau yog ntxiv nrog tooj liab los txhim kho nws cov kev tiv thaiv kom muaj zog txo acids, xws li sulfuric acid. Cov hlau kuj tseem tiv taus kev ntxhov siab corrosion cracking thiab crevice corrosion. Qib 904L yog non-sib nqus, thiab muaj cov qauv zoo heev, toughness thiab weldability.
904L alloy yog super austenitic stainless hlau tsim rau ntau yam nruab nrab thiab siab corrosion kuj ib puag ncig. Cov ntsiab lus siab ntawm chromium thiab npib tsib xee, ua ke nrog molybdenum thiab tooj liab raws li kev sib xyaw ntawm cov khoom, xyuas kom zoo corrosion kuj ntawm cov khoom.
Nrog rau siab alloy tshuaj muaj pes tsawg leeg ntawm 25% npib tsib xee thiab 4.5% molybdenum, 904L yog superior rau 316L thiab 317L stainless hlau nyob rau hauv tsis kam mus chloride kev nyuaj siab corrosion cracking, pitting thiab corrosion kuj.
Lub 904L alloy yog Ameslikas tsim rau corrosion kuj nyob rau hauv dilute sulfuric acid. Nws kuj muaj qhov zoo corrosion kuj rau lwm cov inorganic acids (xws li kub phosphoric acid) thiab feem ntau cov organic acids.
Lub 904L alloy yog yooj yim welded thiab machined nyob rau hauv lub khw tsim kev coj ua

Corrosion Resistance
Qib 904L stainless hlau muaj kev tiv thaiv zoo rau cov dej hiav txwv sov thiab cov tshuaj chloride nres. Lub siab tsis kam ntawm qib 904L tiv thaiv kev ntxhov siab corrosion tawg yog vim muaj cov nyiaj npib tsib xee ntau hauv nws cov muaj pes tsawg leeg. Tsis tas li ntawd, qhov sib ntxiv ntawm tooj liab rau cov qib no txhim kho kev tiv thaiv sulfuric acid thiab lwm yam kev txo qis hauv ob qho tib si txhoj puab heev thiab mob me.
Kev tiv thaiv corrosion ntawm qib 904L yog nruab nrab ntawm cov qib super austenitic, nrog 6% molybdenum cov ntsiab lus, thiab cov qauv 316L austenitic qib. Qib 904L tsis tshua muaj zog rau nitric acid dua qib 304L thiab 310L, uas tsis muaj molybdenum. Cov qib steel no yuav tsum tau muab tshuaj kho tom qab ua haujlwm txias, kom ua tiav qhov siab tshaj plaws corrosion cracking kuj nyob rau hauv ib puag ncig tseem ceeb.
Cov ntaub ntawv Fabrication
Thaum tshav kub kub Resistance
Qib 904L stainless hlau muaj oxidation zoo. Txawm li cas los xij, cov qauv kev ruaj ntseg ntawm qib no poob qis ntawm qhov kub thiab txias, tshwj xeeb tshaj yog siab dua 400 degree.
Kev kho cua sov
