Yog hais tias koj nyob nraum sourcing stainless hlau piping rau kev lag luam, txiv hmab txiv ntoo, lossis kev paub huv, ib qho ntawm cov khoom lag luam stainless feem ntau? Thaum ob qho tib si ntawm cov neeg siv tsis tau cov tsev neeg tsis muaj roj stainless hlau, 304 thiab 316 qhov kev muaj qhov zoo nyob ntawm koj qhov kev ua haujlwm tshwj xeeb. Kab lus no tsoo qhov sib txawv tseem ceeb hauv tshuaj lom neeg, corrosion tsis kam, raug nqi, pab koj ua qhov kev txiav txim siab yuav khoom.

Dab tsi yog 304 stainless hlau yeeb nkab?

AISI 304 Stainless hlau yeeb nkab hlau yog qhov qis}} cov pa roj carbon monoxide}}}}}}}}}}}}}.}% Npib raws li cov tseem ceeb. Nws yog rau 18-8 qib classic (sib raug rau en 1.4301). Nws yog dav siv nyob rau hauv dav dav ib puag ncig ntawm ib txwm kub thiab siab. Nws yog lub hom phiaj dav dav hlau stainless hlau nrog kev ua tau zoo heev ntawm kev lag luam thiab pej xeem teb.

316 Cov Yeeb Nkab Stainless Hlau Yog Dab Tsi?

AISI 316 Stainless hlau yeeb nkab steel yog ib tug aub stainless hlau yeeb nkab nrog 2-3% molybdenum tau ntxiv rau 304 (sib piv rau en 1.4401 / 1.440). Nws qhov kub tiv thaiv thiab cov khoom siv tshuab tau zoo dua li 304. Nws yog qhov tsim nyog rau cov tshuaj thiab cov khoom siv dej, cov khoom siv dej hiav txwv engineering thiab lwm yam scenes.

Qhov txawv ntawm 304 thiab 316 Stainless Hlau Yeeb Nkab

Ua yeeb yam
304 Austenic Alloy Steel Yeeb Nkab yog hom qauv hlau tshaj plaws. Raws li ib qho khoom siv hlau ntau, nws muaj cov khoom lag luam tsis zoo, kub tsis kam, tsawg kub lub zog thiab cov khoom siv tshuab. Zoo kub ua haujlwm xws li Stamping thiab khoov. Tsis muaj cua sov kho cua daj cua sov zoo li cas (tsis -} sib nqus, siv kub -196℃~ 800 degree).

Vim yog qhov sib ntxiv ntawm molybdenum, ss 316 yeeb nkab tau tshwj xeeb corrosion zoo, atmospheric corrosion, thiab kub siab. Tuaj yeem siv hauv cov xwm txheej hnyav. Zoo heev ua haujlwm nyuaj (tsis - sib nqus).

Corrosion Kuj
304 Stainless yeeb nkab ua yeeb yam zoo tshaj plaws hauv kev ua haujlwm ntawm cov huab cua, thiab cov kuab tshuaj ntsuab, ua rau nws zoo tshaj rau cov tub rog, tshuaj lom neeg thiab ntug dej hiav txwv.

Tus nqi
316 Stainless hlau Tubing yog feem ntau 20-30% ntau dua 304 vim yog qhov qis dua hauv kev saib xyuas thaj tsam. Kev kho dua tshiab, thiab lub neej pabcuam ntev dua.

Tau 304 hloov 316?
Nws tuaj yeem siv rau hauv qhov chaw ib puag ncig, tab sis nws yuav ua rau lub neej tsis txaus thiab txawm ua rau muaj kev nyab xeeb kev nyab xeeb hauv cov tshuaj chlorine thiab cov yeeb yaj kiab siab.

Dab tsi yog qhov sib txawv ntawm 304 thiab 316 piping?

Xaiv ntawm 304 thiab 316 cov kav hlau stainless yog nyob ntawm koj ib puag ncig ib puag ncig, nyiaj txiag, thiab cov kev xav tau kev ua tau zoo. Yog tias koj ua haujlwm hauv kev xeb, ntug dej hiav txwv, lossis tshuaj lom neeg {}} Cov mob hnyav, 316 yog qhov kev daws teeb meem ntev. Rau cov qauv txheem sab hauv lossis dav - hom phiaj siv, 304 muaj txiaj ntsig zoo heev.
