Stainless hlau yog ib qho kev xaiv nrov rau ntau yam kev siv vim nws cov corrosion kuj, durability, thiab versatility. Qhov ob feem ntau siv stainless hlau qib yog 304 thiab 316, ob qho tib si uas muaj cov khoom tshwj xeeb thiab qhov zoo. Nov yog yuav ua li cas xaiv ntawm ob:
1. Corrosion resistance: Ob qib muab kev tiv thaiv corrosion zoo heev, tab sis 316 yog superior rau 304 nyob rau hauv ib puag ncig uas muaj cov chlorides siab, xws li marine los yog ntug hiav txwv daim ntaub ntawv. Yog tias koj daim ntawv thov cuam tshuam nrog cov dej ntsev, tshuaj lom neeg, lossis cov kua qaub ib puag ncig, 316 yog qhov kev xaiv zoo dua.
2. Lub zog: 316 kuj tseem muaj zog dua 304, ua kom nws haum rau kev siv hnyav. Txawm li cas los xij, 304 tseem yog cov khoom siv muaj zog thiab tuaj yeem yog qhov kev xaiv zoo dua rau cov ntawv thov qhov hnyav yog qhov kev txhawj xeeb.
3. Tus nqi: 304 feem ntau tsis tshua kim tshaj 316, ua rau nws muaj kev xaiv pheej yig dua rau ntau daim ntawv thov. Yog tias tus nqi yog qhov kev txhawj xeeb tseem ceeb thiab koj daim ntawv thov tsis tas yuav muaj kev tiv thaiv corrosion ntau dua ntawm 316, 304 yog qhov kev xaiv zoo.
4. Weldability: Ob qib tau yooj yim welded, tab sis 316 yog qhov nyuaj dua rau vuam vim nws cov ntsiab lus carbon ntau dua. Yog tias vuam yog qhov tseem ceeb ntawm koj daim ntawv thov, 304 yuav yog qhov kev xaiv zoo dua.
Hauv cov ntsiab lus, thaum xaiv cov qib stainless hlau 304 thiab 316, xav txog cov kev xav tau tshwj xeeb ntawm koj daim ntawv thov. Yog tias kev tiv thaiv corrosion yog qhov tseem ceeb tshaj plaws, 316 yuav yog qhov kev xaiv zoo dua. Yog tias lub zog lossis tus nqi yog qhov kev txhawj xeeb loj dua, 304 yog qhov kev xaiv zoo. Tham nrog ib tus kws kho hlau lossis tus kws paub txog cov khoom siv los xaiv cov qib stainless hlau zoo rau koj daim ntawv thov.
