Nyob rau hauv lub ntiaj teb no ntawm kev lag luam kev siv, kev xaiv ntawm cov ntaub ntawv muaj peev xwm cuam tshuam rau kev ua tau zoo, durability, thiab tag nrho cov kev vam meej ntawm ib qhov project. Cov khoom siv feem ntau siv hauv cov kav dej yog cov yeeb nkab steel hlau, tshwj xeeb yog qib 304 thiab 316. Thaum ob qho tib si yog cov kev xaiv nrov, lawv muaj cov khoom tshwj xeeb uas ua rau lawv haum rau kev siv sib txawv. Cov lus qhia no yuav ua tib zoo saib qhov sib txawv ntawm Suav 304 stainless hlau yeeb nkab thiab 316 stainless hlau yeeb nkab, pab koj txiav txim siab rau koj qhov project tom ntej.
** 304 stainless hlau yeeb nkab: multifunctional khoom tseem ceeb **
304 Stainless Steel Pipe feem ntau hu ua "workhorse" ntawm tsev neeg stainless hlau. Uas feem ntau ntawm cov hlau, chromium (18%), thiab npib tsib xee (8%), qib no paub txog nws cov kev tiv thaiv zoo corrosion, zoo formability, thiab weldability. Nws yog siv nyob rau hauv ntau yam kev lag luam, nrog rau kev ua zaub mov, kev cia tshuaj, thiab kev tsim kho.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm 304 stainless hlau yog tias nws tuaj yeem tiv taus ntau qhov kub thiab txias, ua rau nws haum rau ob qho tib si kub thiab tsis kub. Tsis tas li ntawd, nws tsis yog hlau nplaum thiab muaj ib qho chaw du, uas yog qhov tseem ceeb rau kev nyiam huv hauv kev lag luam khoom noj. Txawm li cas los xij, thaum 304 stainless hlau muaj kev tiv thaiv zoo rau oxidation thiab corrosion, nws tsis ua haujlwm zoo nyob rau hauv ib puag ncig corrosive, tshwj xeeb tshaj yog cov uas muaj chlorides.
** 316 stainless hlau yeeb nkab: tus yeej ntawm corrosion kuj **
Ntawm qhov tod tes, rau cov ntawv thov uas xav tau kev txhim kho corrosion, 316 stainless hlau yeeb nkab feem ntau suav hais tias yog qhov kev xaiv zoo tshaj plaws. Cov qib no muaj cov feem pua ntawm cov npib tsib xee (10%) thiab molybdenum (2%), uas ua rau nws zoo dua rau pitting thiab crevice corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig chloride nplua nuj. Yog li, 316 stainless hlau yog cov khoom xaiv rau kev siv dej hiav txwv, kev ua tshuaj, thiab kev lag luam tshuaj.
Qhov sib ntxiv ntawm molybdenum tsis tsuas yog txhim kho corrosion kuj, tab sis kuj txhim kho tag nrho lub zog thiab kav ntev ntawm cov khoom. 316 stainless hlau kav tuaj yeem tiv taus qhov kub thiab txias thiab tsis tshua muaj kev ntxhov siab corrosion tawg. Qhov no ua rau lawv zoo tagnrho rau kev siv nyob rau hauv ib puag ncig hnyav, xws li cov chaw ntug hiav txwv lossis cov nroj tsuag tshuaj uas feem ntau raug rau cov tshuaj corrosive.
** Qhov txawv ntawm qhov tseem ceeb: Cov ntsiab lus sib piv **
1. **Corrosion Resistance**: Thaum ob leeg 304 thiab 316 stainless hlau kav muaj corrosion kuj zoo, 316 ua tau zoo tshaj 304 nyob rau hauv ib puag ncig uas muaj chloride ntau. Qhov no ua rau 316 qhov kev xaiv zoo tshaj plaws rau kev siv dej hiav txwv thiab tshuaj lom neeg.
2. **Composition**: Qhov sib txawv tseem ceeb hauv kev muaj pes tsawg leeg yog molybdenum ntxiv rau 316 stainless hlau, uas ua rau nws tsis kam mus rau pitting thiab crevice corrosion.
3. ** Nqi **: Feem ntau hais lus, 316 stainless hlau yeeb nkab yog kim dua 304 stainless hlau yeeb nkab vim qhov sib ntxiv ntawm alloying ntsiab. Yog li ntawd, kev xaiv ntawm ob feem ntau yog nyob ntawm cov kev cai tshwj xeeb ntawm daim ntawv thov thiab kev xav txog nyiaj txiag.
4.** Daim ntawv thov**: 304 stainless hlau yog tsim rau ntau yam kev siv, nrog rau kev siv cov khoom noj thiab kev tsim kho, thaum 316 stainless hlau yog tsim los rau ntau qhov chaw xav tau, xws li marine thiab tshuaj ua haujlwm.
** nyob rau hauv xaus **
Xaiv Tuam Tshoj 304 stainless hlau yeeb nkab lossis 316 stainless hlau yeeb nkab kawg yog nyob ntawm qhov xav tau tshwj xeeb ntawm koj qhov project. Nkag siab txog qhov sib txawv ntawm qhov sib txawv, kev tiv thaiv corrosion, thiab daim ntawv thov tsim nyog yuav pab koj txiav txim siab paub. Txawm hais tias koj xav tau qhov kev ua tau zoo ntawm 304 lossis kev txhim kho ruaj khov ntawm 316, ob qib muab kev ua tau zoo thiab kev ntseeg siab hauv lawv cov haujlwm. Ua lag luam nyob rau hauv txoj cai stainless hlau yeeb nkab rau koj cov kev xav tau los xyuas kom meej tias koj qhov project ua tiav rau xyoo tom ntej.
