SS904L AISI 904L Cov Hlau Tsis Xeb (UNS N08904)
Kev Taw Qhia Txog Khoom
AISI 904L stainless hlau (UNS N08904) yog cov hlau stainless hlau austenitic siab. Piv nrog 316L, SS904L muaj cov ntsiab lus carbon (C) qis dua, cov ntsiab lus chromium (Cr) siab dua, thiab kwv yees li ob npaug ntawm cov ntsiab lus nickel (Ni) thiab molybdenum (Mo) ntawm316L, uas ua rau nws muaj qhov kub siab dua oxidation tsis kam, pitting tsis kam, thiab tsis kam txo cov kua qaub (piv txwv li, sulfuric acid). Nitrogen (N) tuaj yeem txo qhov nrawm ntawm chromium carbide precipitation, yog li txo qhov rhiab heev ntawm sensitization, nws kuj txhim kho qhov tsis kam rau pitting thiab crevice corrosion los ntawm chlorides. Tshwj xeeb tshaj yog nws ntxiv tooj liab (Cu) ua rau nws muaj txiaj ntsig rau txhua qhov concentration ntawm sulfuric acid.
Alloy 904L ua tau zoo dua li lwm cov hlau tsis xeb austenitic vim muaj cov hlau nickel thiab molybdenum ntau dua. Cov qib no tsis yog hlau nplaum hauv txhua qhov xwm txheej thiab muaj kev ua tau zoo heev thiab kev vuam. Cov qauv austenitic kuj muab qib no zoo heev rau kev tawv, txawm tias mus txog qhov kub cryogenic. Cov ntsiab lus chromium siab txhawb nqa thiab tswj hwm cov yeeb yaj kiab passive uas tiv thaiv cov khoom siv hauv ntau qhov chaw corrosive. Tsis muaj kev pheej hmoo ntawm kev xeb intercrystalline ntawm kev txias lossis vuam vim muaj cov ntsiab lus carbon tsawg. Nws qhov kub siab tshaj plaws yog ntawm 450 ° C. Qib no yog qhov tshwj xeeb tshaj yog siv rau kev tswj hwm thiab cov cuab yeej siv tubing uas 316 thiab 317L tsis haum.
Alloy 904L tau tsim thawj zaug los tiv taus cov chaw muaj cov kua qaub sulfuric dilute. Nws kuj tseem muaj kev tiv taus zoo rau lwm cov inorganic acids xws li cov kua qaub phosphoric kub thiab feem ntau cov organic acids.
Alloy 904L yog yooj yim welded thiab ua tiav los ntawm cov qauv kev tsim khoom hauv khw.
904L stainless hlau (SS904L) yog siv rau hauv roj av, tshuaj lom neeg, chiv, cov pej thuam tsim kho dej hiav txwv, cov thoob dej, cov kav dej thiab cov raj xa dej thiab cov khoom hloov pauv cua sov. Rolex thiab lwm cov chaw tsim khoom siv moos kuj siv nws los ua moos.
