Muaj ob hom ntawm cov hlwv hauv av tsis muaj roj
300 series cov hlau stainless feem ntau paub nws cov qauv Austenic los ntawm kev ntxiv npib tsib xee. Hom 304 stainless hlau thiab 316L stainless hlau muaj rau cov series no. Lub 200 series stainless hloov manganese thiab nitrogen hloov npib tsib xee, thiab cov ntsiab lus tsib xee yog qhov tsawg heev. Cov hom 201 stainless hlau thiab 202 stainless hlau muaj rau cov series no.
300 series stainless hlau yog qhov loj dua. Qhov feem ntau cov thiab feem ntau hom ustenitic stainless hlau yog hom 304, tseem hu ua 18/8 lossis A2. Cov khoom xws li 304 stainless cov khoom lag luam, tshuab ua noj thiab chav ua noj. 316 series stainless hlau yog qhov tom ntej feem ntau feem ntau feem ntau feem ntau atustenitic steel hlau. Kwv yees li 300 series, xws li hom 316, tseem muaj qee cov molybdenum los txhawb rau cov kua qaub thiab nce ntxiv rau cov chaw nres tsheb hauv zos (xws li pitting thiab compevice corrosion).
Qhov siab dua nitrogen ntxiv nyob rau hauv 200 series muab nws ntau dua txhua yam muaj zog ntawm 300 series. Austenitic Stainless hlau yog hom 309 thiab 310 rau cov ntawv thov kub siab dua 800 ° C. Cov yam ntxwv ntawm 200 series stainless corrosion: thaum 200 series yog tsawg dua li 300 koob los tiv thaiv pitture, uas ua rau cov kua dej siab, uas ua rau muaj kua ntshauv, uas ua rau ib puag ncig kua dej thiab cov khoom siv acid. Qhov no yog vim tias, nyob rau hauv thiaj li yuav txo cov ntsiab lus tsib xee, cov ntsiab lus chromium yuav tsum raug txo kom tseem yuav raug txo kom tsawg, yog li txo cov corrosion tsis kam.
200 series stainless cov hlau yog cuam tshuam kev cuam tshuam thiab tawv txawm tias tsawg kub. Lawv feem ntau nyuaj dua li 300 daim hlau sib tw, feem ntau vim yog lawv cov ntsiab lus nitrogen, uas ua raws li tus neeg sawv cev txhawb. Vim tias lawv yog Austenitic, 200 thiab 300 series hlau yog pheej yig. Txawm li cas los xij, qhov muaj peev xwm (ductility) ntawm 200 series steel yog qis dua li ntawm 300 series hlau, txawm hais tias qhov no tuaj yeem txhim kho los ntawm kev ntxiv tooj liab.
Alloy 20 (Kws Ntoo Ntoo 20) yog ib qho kev ua kom tsis muaj roj stainless hlau uas muaj kev tiv thaiv zoo heev rau cov sulfuric acid thiab ntau lwm qhov chaw nres tsheb 316 stainless hlau. Lub Alloy cov khoom ua pov thawj tsis zoo rau kev ntxhov siab corrosion tawg nyob rau hauv boiling 20-40% sulfuric acid. Alloy 20 muaj cov kws kho zoo dua tshiab thiab muaj Niobium hauv cov alloy minimizes carbide nag lossis daus thaum lub sij hawm vuam. Raws li cov yam ntxwv sib txawv ntawm cov khoom sib txawv ntawm cov khoom sib txawv, kev ua yeeb yam thiab faib cov arches yuav tsum sib txawv, yog li ntawd qhov kev ua kom muaj zog me me thiab muaj cov khoom siv zoo tuaj yeem tau txais. Yog li ntawd, Hangao Tech (Seko Machinery) yuav ib txwm sib txuas lus nrog lawv txog ntau yam tsis tau, tom qab tau txais cov lus nug los ntawm cov neeg siv khoom muaj tseeb txog kev daws teeb meem txog Stainless Hlau Muaj yeeb nkab ntau lawm Kab Tube zeb Machinery Uas tau raws li kev xav tau tsim ntau lawm.
Kev kuaj cov hlau tsis tuaj yeem kuaj xyuas los ntawm kev kuaj tsis yog kev rhuav tshem cov txheej txheem, lossis siv Eddy kev sim tam sim no, tab sis tsis yog los ntawm kev sib nqus particetic tshuaj ntsuam txoj kev.
