304 steel phaj thiab 316 Stainless Hlau Phaj
Dab tsi yog qhov sib txawv ntawm 304 steel phaj thiab 316 stainless hlau phaj
Qhov sib txawv ntawm kev sib txawv ntawm 304 thiab 316 stainless tus neeg nyob hauv lawv cov lus thiab ua rau corrosion rau chloride, uas txhim kho nws cov kev siv mary corrosion lossis bulk devenance rau cov tshuaj cog qoob loo lossis chaw hnyav nrog cov tshuaj lom neeg. Thaum ob qho tib si yog Austenitic thiab feem ntau tsis yog sib nqus, 316 stainless hlau muaj cov khoom siv zoo dua thiab feem ntau kim dua.
Cov hlau nplaum tuaj yeem nyiam 304 stainless hlau?
Feem ntau, cov hlau nplaum tsis nyiam 304 stainless hlau muaj zog, raws li nws feem ntau Austenitic thiab paub rau kev tsis sib nqus. Txawm li cas los xij, kev ua haujlwm txias (xws li khoov, dov, lossis machinustenite theem los hloov mus rau martensite, uas yog sib nqus. Yog li ntawd, thaum cov hlau nplaum yuav tsis nyiam 304 stainless hlau muaj zog, nws yuav ua rau qee qhov tsis muaj zog sib nqus, tshwj xeeb yog nws tau txias ua haujlwm.
Qhov sib txawv ntawm SS 316 daim hlau thiab SS 304 daim hlau
Thaum piv 316 stainless hlau (SS316) thiab 304 stainless hlau (SS304) muaj ob peb qhov sib txawv. SS316 lub phaj yog ntau dua corrosion-resistant dua li SS304 thiab muaj qhov ntau dua chloride, ua rau nws zoo rau cov kev siv nthuav tawm ib puag ncig corrosive. SS316 kuj tseem muaj ntau lub zog kub siab, nrog kev kub ntxhov txog 900℃/ 1650℃f yam tsis muaj kev cuam tshuam tseem ceeb. SS316 cov khoom pov thawj siab dua ntawm lub zog kub tshaj SS304, thaum ob qho tib si muab cov yam ntxwv zoo heev thiab cov kws kho zoo. Vim tias SS316 muaj ntau dua kev tawm tsam rau pitting thiab crevice corrosion dua cov ntaub ntawv qis dua hauv SS304 lub phaj yuav tsum muaj cov nqi tswj cov nqi qis dua.
Corrosion Kuj
SS 316 phaj feem ntau ntau dua corrosion-resistant dua SS 304 phaj, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig muaj chloride ions. Qhov no yog vim ss 316 lub phaj muaj cov ntsiab lus molybdenum siab dua, uas txhim kho nws txoj kev tiv thaiv kom pitting corrosion. Txawm li cas los xij, SS 304 lub phaj tseem ua tau zoo hauv cov chaw muaj kev nyab xeeb tsawg.
Ob lub 316 thiab 304 cov phiaj hlau stainless yog tsim los ntawm alloy steels, tab sis lawv cov kev sib txawv. SS 304 muaj chromium, npib tsib xee, thaum ss 316 ntau dua corrosion-resistant ntau dua li peb lub sij hawm muaj peb zaug ntawm cov qib kawm.
Lub zog
SS 316 Phaj muaj lub zog siab dua thiab tawm lub zog dua SS 304 phaj. Lub zog no siab dua yog ntaus nqi rau kev ntxiv ntawm Molybdenum thiab ntau dua npib tsib xee nyob hauv SS 316 phaj. Txawm li cas los xij, SS 304 phaj tseem muaj lub zog txaus rau feem ntau cov ntawv thov.
SS 316 thiab SS 304 phaj sib txawv hauv lawv cov tshuaj muaj kuab lom. Qhov sib txawv ntawm 2% -3% Molybdenum rau SS 316, uas ua rau nws muaj ntau corrosion-resistant ntau dua li SS 304 phaj. SS 316 lub phaj tseem muaj lub zog ntau dua thiab muaj peev xwm tiv taus qhov kub thiab txias, ua rau nws ruaj khov. Vim nws cov ntsiab lus molybdenum siab dua, SS 316 lub phaj tseem tiv taus pittingist rau pitting thiab crevice corrosion hauv cov chaw sov sov.
