Qhov sib txawv tseem ceeb ntawm 316 stainless hlau thiab 316L stainless hlau daim hlau
Qhov sib txawv tseem ceeb ntawm 316 stainless hlau thiab 316L stainless hlau daim hlau
Qhov sib txawv tseem ceeb ntawm 316 thiab 316L stainless hlau daim hlau nyob hauv lawv cov ntsiab lus carbon: 316L ("L" sawv cev rau cov pa roj carbon tsawg) muaj cov ntsiab lus siab tshaj plaws ntawm 0.03%, thaum tus qauv 316 daim hlau tuaj yeem muaj cov ntsiab lus carbon txog 0.08%. Cov ntsiab lus qis dua ntawm 316L daim hlau ua rau lawv haum rau vuam, tiv thaiv "weld decay" (intergranular corrosion), thiab yog li zoo tagnrho rau hnyav -cov haujlwm welded qauv. 316 stainless hlau daim hlau muaj zog dua me ntsis, tab sis yuav tsum tau annealing tom qab vuam kom ua tau zoo corrosion kuj.
Dab tsi yog qhov tshwj xeeb ntawm 316 stainless hlau?
SAE 316 Stainless hlau
Nws muaj kev tiv thaiv corrosion zoo heev, tshwj xeeb tshaj yog tiv thaiv chlorides thiab lwm cov kuab tshuaj ua haujlwm. Nws muaj lub zog zoo me ntsis, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias, thiab tiv taus pitting thiab crevice corrosion. Nws tuav nws txoj kev ruaj ntseg thiab lub zog txawm tias thaum kub kub.
Dab tsi yog 316L stainless hlau phaj?
316L stainless hlau phaj yog qis- carbon version ntawm 316 stainless hlau, tsim los txo qis carbide nag lossis daus thaum vuam. Yog li ntawd, nws yog cov khoom siv zoo tshaj plaws rau cov ntawv thov uas yuav tsum tau siv dav hauv vuam lossis raug rau qhov chaw corrosive ntawm qhov kub thiab txias. Nws tuav lub zog zoo heev thiab corrosion kuj thaum muab kev txhim kho weldability thiab txo kev pheej hmoo ntawm kev tawg.
Dab tsi yog 316 stainless hlau phaj?
316 stainless hlau phaj yog dav siv nyob rau hauv marine, tshuaj, thiab kev lag luam daim ntaub ntawv vim nws siab corrosion kuj thiab lub zog. Nws muaj molybdenum, uas txhim kho nws cov kev tiv thaiv rau pitting thiab crevice corrosion, tshwj xeeb tshaj yog nyob rau hauv chloride - nplua nuj ib puag ncig. Nws cov ntsiab lus carbon siab dua muab qhov nyuaj dua, ua rau nws haum rau hnyav- cov qauv thiab cov khoom siv.

316 vs . 316L: Qhov txawv ntawm qhov tseem ceeb
Weldability:
316L yog qhov tsim nyog rau kev vuam vim tias nws cov ntsiab lus qis qis tiv thaiv carbide nag lossis daus (weld decay), kom ntseeg tau zoo corrosion kuj tom qab vuam.
316 tej zaum yuav muaj weld lwj yog tias tsis annealed tom qab vuam, tab sis nws tseem pom tau tias muaj weldability zoo.
Corrosion Resistance:
Ob leeg muaj kev tiv thaiv corrosion zoo heev, tab sis 316L zoo dua me ntsis, tshwj xeeb tshaj yog nyob rau hauv cov pob qij txha welded thiab siab -chloride / siab- qhov kub thiab txias, vim nws txo qhov kev pheej hmoo ntawm intergranular corrosion.
Lub zog / Kub Resistance:
Vim nws cov ntsiab lus carbon ntau dua, 316 feem ntau muaj me ntsis siab dua txhua yam lub zog thiab kub tsis kam tshaj 316L.
