Qhov sib txawv ntawm 304, 304L, 304n thiab 304h- cov ntaub ntawv

Thaum ntxuav cov hlau Stainless los ntawm koob304, nws yog qhov tseem ceeb kom nkag siab txog qhov sib txawv ntawm304, 304L, 304nthiab30H, tshwj xeeb tshaj yog rau kev yuav cov kws tshaj lij kev yuav khoom uas yuav tsum tau nrhiav qhov kev pom raws kev ua kom zoo ntawm corrosion tsis kam, muaj zog thiab tus cwj pwm kub. Cov hlau tsis huv no tau siv dav hauv cov cuab yeej siv tshuaj, cov piping, thiab lawv cov carbon thiab cov pa roj carbon monoxide, tab sis lawv cov pa roj carbon thiab nitrogen txiav txim siab lawv cov ntawv thov tshwj xeeb.

304l stainless hlau

Tus txheej txheem suav rau stainless hlau30LyogS30403Cov. Nws cov ntsiab lus carbon yog txo qis dua0.03%, uas tsis tsuas yog txhim kho corrosion tsis kam tab sis kuj mitigates lubsiab zooThiab tusintergranular corrosiontshwm sim los ntawm cov nag lossis daus ntawm carbides nyob rau hauv thaj tsam ntawm 450℃- {{{} {degree ntawm lub neej muaj txiaj ntsig ntawm cov welds. Tsis tas li ntawd, tus30LNws tau zoo dua ductility tshaj 304, yog li nws tuaj yeem hloov nws rau ntau lub sijhawm.

304n Stainless Hlau

Cov khoom tseem ceeb ntawm4NLawv zoo ib yam li 304, tab sis nws yog lub hlau stainlessnitrogen ntxivCov. Qhov sib ntxiv ntawm nitrogen nce nws cov neeg siv tshuab tsis kam; Yog li ntawd, tus4NNws yog ib qho siv nyob rau hauv cov ntawv thov uas xav tau kev ua haujlwm siab hauv kev txias.

Cov Ntsiab Lus Tseem Ceeb:

30L: Nyiam rau welded kev tsim kho vim nws cov ntsiab lus muaj roj carbon tsawg.

4N: Muaj cov neeg siv tshuab ntau dua tsis kam ua tsaug rau nitrogen.

30H: Qhov zoo tagnrho rau cov ntawv thov kub siab, tswj kev tiv thaiv ntawm 500-800 degrees.

Nqe sib txawv ntawm 304, 304L, 304n, 304h

Tus nqi ntawm hlau304ranges nruab nrab ntawmUSD 2.50-3.20 / kg, ua tus30LMe ntsis siab dua (USD 2.60-3.40 / kg) Vim nws cov tshwj xeeb uas muaj kev tsim khoom me me. Cov degrees4Nthiab30HLawv feem ntau yog a10-15% kim kimVim yog cov nitrogen lossis cov ntsiab lus carbon.

Dab tsi yog qhov sib txawv ntawm 304L thiab 304H?

Lub ntsiab sib txawv yog cov ntsiab lus carbon, uas cuam tshuam nws lub ntsiab siv:30LNws muaj cov pa roj carbon tsawg kom tsis txhob corrosion tom qab vuam, ua qhov zoo tagnrho rau welded daim ntawv thov, thaum lub30HNws muaj ntau dua cov pa roj carbon ntau rau ntau dua kev tiv thaiv kom muaj kub, ua kom haum rau boilers thiab kev hloov cua sov.

Vim li cas xaiv 304n tshaj 304 lossis 304L?

Nws4NNtxiv0.10-0.16 wt% nitrogen, nce cov paib muaj zog los ntawm ~ 20% (≈ 260 MPA), ua kom pom kev sib tw loj thiab nce qhov kev ua tau zoo hauv chloride-nplua nuj lossis cryogenic ib puag ncig.

Dab tsi yog qhov sib txawv ntawm 304L thiab 304LN?

NwsYogNws yog Ameslikas tsim los ua lub zog siab dua ntawm 304L siv nitrogen. Txawm li cas los xij, kev nce hauv lub zog yog coj nruab thiab tsuas yog cov qib duuplex tam sim no siv rau lub hom phiaj ntawd. Tam sim no siv tau hauv cov ntawv teev tshwj xeeb uas aTsawg heev sib nqus lus tebCov.
