304 Stainless hlau yog qhov feem ntau cov hlau tsis muaj. Cov hlau muaj ob txoj kev chromium (nruab nrab ntawm 18% thiab 20%) thiab thib pua (nruab nrab ntawm 8%) [1] cov hlau uas yog cov qauv hlau tseem ceeb. Nws yog Austenitic stainless hlau.When nws los txog siv, SS304 tuaj yeem pom hauv chav ua noj hauv chav dej thiab lwm yam khoom siv xws li toaster thiab microwave ncu. SS304 kuj yog siv los ua kom cov hlab ntsha siab, lub log npog zoo li rau kev ua lub tsev kws ua liaj ua teb.

Duplex steel s31803 Reducer fittings yog tiv taus chloride ib puag ncig thiab sulfide kev nyuaj siab corrosion. Lub caij no, cov chav dej dulex s3180 hla cov xaim hluav taws xob tseem muaj rau peb cov neeg siv khoom sib txawv thiab cov duab. Duplex steel s31803 khoov pob tw welded yeeb nkab fittings feem ntau ua tau zoo nyob rau hauv ib puag ncig uas ua rau muaj kev ua ntej ntawm cov qib tsis ua haujlwm. Txawm hais tias tus pas dej Duplex S31803 luv luv khawm welded cov khaub noom fittings muaj qhov kub ntawm lub sijhawm yog tias muaj qhov kub nyob rau ntawm 300 degrees Celsius.

Peb tsim Sa403 WP 304 luv luv voj voog thiab ntev rapius elbows muaj zog heev zog ntawm 205mpa thiab tsawg kawg tensile lub zog ntawm 515MPA. Cov haujlwm no tau zoo nyob rau hauv cov kev kub siab ib puag ncig mus txog 870 degrees Celsius.

Lub hauv paus cov khoom siv rau Astm A234 WPB Hlau Yeeb Nkab Fittings tuaj yeem yog los ntawm cov phaj hlau xws li Astm A285 Gr.16 Gr 50, ASTM A512 thiab lwm yam.

Cov ntsev ntsev no tuaj yeem txhim kho thaum hydrochloric acid los sib cuag nrog hlau thiab tooj liab. Yog li ntawd, yog tias cov khoom siv no ua ke nrog cov hlau lossis cov raj tooj liab hauv cov kab ke thiab cov khw muag khoom siv hydernoric tuaj yeem ua rau lub ntsej muag ua ntej ua ntej.

Hmoov tsis zoo li S32100 thiab qib 32% rau 19% rau 1 xee, .70% titanium, nrog qhov sib npaug yog hlau. Nrog rau kev cuam tshuam rau corrosion tsis kam, 321 stainless hlau yog sib npaug rau qib 304 nyob rau hauv anealed mob thiab zoo dua yog tias daim ntawv thov cuam tshuam nrog 797¡Ã li 1652¡Ã f ntau. 321 Stainless hlau ua ke siab lub zog, tiv taus rau scring thiab theem kev ruaj khov nrog kev tiv thaiv a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a axoous.

Rau cov ntawv sau zeb hauv av uas xav tau cov qib qis dua uas tsis muaj cov xeb txaus tiv thaiv. Raws li 22% chromium cov ntsiab lus, lawv muaj cov ustenitic: Ferritic microstructure uas muaj zog dua, corrosion tsis kam thiab nqi-ua hauj lwm zoo.
