Puas yog Sus304 thiab SS304 yuav siv sib hloov pauv?
Hauv cov xwm txheej dav dav, lawv tuaj yeem siv sib hloov pauv, tab sis nws yog ib qho tsim nyog los xyuas kom meej tias lawv ua tau raws li cov ntawv pov thawj kev lag luam (xws li en 1.4301 rau export rau EU).
Qhov twg yog kim dua, sus304 lossis SS304?
Tus nqi yog zoo sib xws rau tib cov lus qhia tshwj xeeb, tab sis SS304 yuav kim me ntsis yog tias nws muaj cov ntawv pov thawj ntxiv (xws li ASME).
Sus304 Stainless Hlau Corrosion Kuj
Nws muaj qhov zoo heev corrosion tsis kam rau cov huab cua, dej, qaug zog acid thiab alkali (xws li kev ua zaub mov noj), uas yog qhov zoo dua li cov pa roj carbon hlau. Los ntawm kev kho cov tshuaj (quenching ntawm 1010-1150 degree), intergranular chromium qhov tsis muaj vuam corrosion.
Sus304 Stainless Hlau Ua Kev Zoo
Nws muaj cov qauv siv tau zoo, yog qhov yooj yim rau stamp, khoov thiab weld, thiab haum rau cov qauv tsim ua cov qauv kev lag luam nyuaj.

Sus304 Stainless Hlau Kub Kuj
Lub sijhawm luv luv siv tau kub yuav ncav cuag 870 degree, thiab lub sij hawm ntev ua haujlwm yog tsawg dua lossis sib npaug nrog 53L degree, uas yog qhov zoo dua 304L (cov pa roj carbon qis).
Sus304 Stainless Hlau Thaum Tshav Kub Kub Kho Mob
Kev Kho Mob:Feem ntau, sus304 yog rhuab rau ntawm 1010 degree -1150}} kawm, thiab tom qab ntawd txias txias, feem ntau los ntawm dej txias. Kev kho cov tshuaj muaj peev xwm ua kom yaj tag nrho cov alloy cov ntsiab lus hauv Austenite, tshem tawm cov kev ntxhov siab thiab txias ua haujlwm tsis kam thiab tawv ntawm cov hlau.
Kev kho kom ruaj khov:Txog qee cov sus304 cov ntaub ntawv uas tau ua haujlwm txias lossis siv nyob rau hauv qhov rhiab heev, yuav tsum muaj kev kho kom nruj. Qhov ntsuas kub ntawm kev kho ruaj khov yog feem ntau ntawm 850 degree {{}} degree, thiab lub sij hawm tuav thawj nyob ntawm qhov xwm txheej tshwj xeeb. Los ntawm kev kho mob ruaj khov, cov carbides hauv cov steel tuaj yeem ua tau tag nrho thiab rov ua dua tshiab, txo qhov rhiab rau intergranular.
Dab tsi yog qhov sib txawv ntawm Sus304 thiab sus316 stainless hlau?
Sus304 (18cr -8 ni) yog ib lub hom phiaj dav dav thiab kev ua tau zoo rau kev ua tau zoo thiab kev tsim kho kom zoo nkauj txhua hnub thiab lwm yam scenes; Thaum sus316 (17Cr -12}} mo ion corrosion (thiab feem ntau li cov pa dej hiav txwv, cov pa roj carbon monoxide) Ob qho tib si tsis yog sib nqus, tab sis sus316 muaj tus nqi ntau dua ntawm Molybdenum thiab tsis tas yuav muaj kev kho cua sov ntxiv tom qab vuam, yog li nws cov kev ua tau zoo dua.
