Lub teb chaws stainless hlau valve steel tooj siv tus qauv tswj steel valve lub ntsiab cov khoom siv rooj

Lub teb chaws stainless hlau valve steel tooj siv tus qauv tswj steel valve lub ntsiab cov ntaub ntawv rooj 321 stainless hlau valve sib npaug rau hauv tsev 1Cr17Ni9Ti, 321 stainless hlau valve kev ua tau zoo zoo ib yam li 304, tab sis vim qhov sib ntxiv ntawm titanium hlau, kom nws muaj kev tiv thaiv zoo dua. rau grain ciam corrosion thiab siab kub zog. Vim yog qhov sib ntxiv ntawm titanium hlau, nws tswj tau qhov tsim ntawm chromium carbide. Lub 321 stainless hlau valve muaj kev ua haujlwm zoo dua Stress Rupture thiab kub siab dua Creep Resistance nyob rau hauv ob qho tib si kev ntxhov siab thiab txhua yam khoom dua li 304 stainless hlau valve. 321 Stainless hlau li qub yog siv rau kev ua haujlwm siab rau lis ciam corrosion Stainless hlau valve lub ntsiab kev ua tau zoo 304 stainless hlau valve GB 0Cr18Ni9, GB 0Cr18Ni9 raws li lub hom phiaj ntawm stainless hlau valve, muaj kev tiv thaiv zoo corrosion, kub tsis kam, kub tsis tshua muaj zog thiab txhua yam khoom. ; Stamping, dabtsi yog khoov thiab lwm yam kub ua tau zoo, tsis muaj kev kho cua sov hardening tshwm sim (tsis muaj hlau nplaum, siv kub -196 ℃ ~ 800 ℃). 321 stainless hlau valve sib npaug rau hauv tsev 1Cr17Ni9Ti, 321 stainless hlau valve kev ua tau zoo zoo ib yam li 304, tab sis vim yog ntxiv ntawm titanium hlau, yog li nws muaj kev tiv thaiv zoo rau cov kab ciam corrosion thiab kub siab zog. Vim qhov sib ntxiv ntawm titanium hlau, nws tswj tau qhov tsim ntawm chromium carbide. Lub 321 stainless hlau valve muaj kev ua haujlwm zoo dua Stress Rupture thiab kub siab dua Creep Resistance nyob rau hauv ob qho tib si kev ntxhov siab thiab txhua yam khoom dua li 304 stainless hlau valve. 321 Stainless hlau valve yog siv nyob rau hauv high grain ciam teb corrosion kuj ntawm tshuaj, thee, roj av kev lag luam nyob rau hauv lub tshav pob ntawm qhib tshav kub resistant pipeline thiab kev kho cua sov yog nyuaj pipeline. 316 stainless hlau valve GB 0Cr17Ni12Mo2 0Cr17Ni12Mo2, vim qhov sib ntxiv ntawm Mo, yog li nws cov kev tiv thaiv corrosion, atmospheric corrosion kuj thiab kub kub lub zog yog tshwj xeeb yog zoo, yuav siv tau nyob rau hauv hnyav tej yam kev mob; 316 stainless hlau li qub siv nyob rau hauv: dej hiav txwv, tshuaj, zas xim, ntawv, oxalic acid, chiv thiab lwm yam khoom siv ntau lawm; 316L stainless hlau valve GB 00Cr17Ni14Mo2 00Cr17Ni14Mo2, raws li 316L stainless hlau valve ntxiv rau 316 stainless hlau valve muaj cov yam ntxwv zoo ib yam, nws cov qoob loo ciam teb corrosion zoo dua 316; Tsis tas li ntawd, qhov sib ntxiv ntawm molybdenum caij tuaj yeem txhim kho nws txoj kev tiv thaiv rau intergranular corrosion thiab oxide kev nyuaj siab corrosion, thiab txo qhov kub kub tawg nyiam thaum vuam. 316L stainless hlau valve yog siv rau hauv: feem ntau siv hauv cov dej ntshiab, dej distilled, tshuaj, ntses, vinegar thiab lwm yam kev noj qab haus huv, kev ua haujlwm nruab nrab corrosion yog lub sijhawm muaj zog, 316 stainless hlau valve tshwj xeeb siv tawm tsam grain ciam corrosion muaj cov khoom tshwj xeeb ntawm cov khoom. 310S stainless hlau valve yog tus qauv qauv ntawm stainless hlau valve nyob rau hauv Teb Chaws Asmeskas, daim ntawv lo hauv tsev yog (2520) 0Cr25Ni20, yog ib hom austenitic stainless hlau valve, S hauv 310S yog hais txog kev siv tshwj xeeb ntawm stainless hlau valve. 0Cr25Ni20 (310S) cov yam ntxwv - kub oxidation tsis kam, siab kub zog. Siv - tso cov yeeb nkab Bellows, microwave qhov cub rhaub, Tube, kub kub rauv zais zis, cremation rauv thiab lwm yam uas yuav tsum tau ntawm tshav kub tsis kam ntawm stainless hlau li qub. Feem ntau ** feem ntau pom 304, 316 stainless hlau valve yog xws li, 304 tus qauv tivthaiv yog 18% chromium ntxiv rau 8% npib tsib xee, uas feem ntau hu ua 18-8 stainless hlau valve. Cov yam ntxwv ntawm hom stainless hlau valve no tsis yog-sib nqus, tsis tuaj yeem hloov pauv los ntawm kev kho cua sov ntawm metallography qauv, kev ua haujlwm zoo, thiab vim yog cov hlau alloy - npib tsib xee, yog li cov corrosion kuj zoo dua tsuas yog muaj chromium (tsis muaj. nickel) ntawm lwm ob hom stainless hlau li qub. Kev siv tseem ceeb ntawm 300 series stainless hlau li qub yog: feem ntau siv hauv roj av, tshuaj, tshuaj, tshuaj chiv, hluav taws xob thiab lwm yam kev lag luam ntawm ntau yam kev ua haujlwm ntawm cov kav dej. Nyob rau hauv lub siab ntawm cov neeg zoo tib yam, lub thiaj li hu ua stainless hlau valve yog hais txog 300 stainless hlau li qub (tshwj xeeb tshaj yog 304 stainless hlau li qub).
