Ntau tus neeg tau yooj yim tsis meej pem 316 stainless hlau yeeb nkab thiab 316L stainless hlau yeeb nkab, xav tias lawv yog tib hom hlau yeeb nkab, tab sis qhov tseeb lawv tsis yog.
Qhov sib txawv tshwj xeeb ntawm 316 thiab 316L stainless hlau yog raws li hauv qab no:
1. Tshuaj muaj pes tsawg leeg
Cov ntsiab lus carbon ntawm 316L stainless hlau yog qis dua li ntawm 316 stainless hlau.Nws tuaj yeem hais tias "316L" yog ib qho tsis tshua muaj carbon 316 stainless hlau.316L stainless hlau muaj cov ntsiab lus molybdenum ntau dua 316.
2. Corrosion kuj
316L stainless hlau muaj zoo corrosion kuj.
3. Lub zog
316 muaj zog mechanical zog.Lub zog tensile ntawm 316 stainless hlau yeeb nkab yog siab dua li ntawm 316L stainless hlau yeeb nkab.Lub zog tensile ntawm 316 stainless hlau yuav tsum muaj ntau dua 520MPa, thaum lub 316L stainless hlau tsuas yog yuav tsum tau ntau dua 480MPa.Qhov no yog vim cov pa roj carbon (C) yog cov khoom muaj zog austenitic, uas tuaj yeem txhim kho lub zog ntawm cov hlau.
4. Kub kub tsis kam
316L stainless hlau tuaj yeem siv tsis tu ncua ntawm qhov kub thiab txias, thaum 316 tsis tuaj yeem.Nyob rau hauv qhov ntau ntawm 800 ~ 1575 degrees, nws yog qhov zoo dua tsis txhob ua tsis tu ncua ntawm 316 stainless hlau.Carbide nag lossis daus tsis kam ntawm 316L stainless hlau zoo dua li ntawm 316 stainless hlau, thiab nws tuaj yeem siv tsis tu ncua nyob rau hauv thaj tsam ntawm 800 ~ 1575 degrees.
5. Vuam
316 stainless hlau muaj qhov zoo weldability, uas tuaj yeem welded los ntawm cov txheej txheem vuam txheej txheem.Lub vuam seem ntawm 316 stainless hlau xav tau tom qab vuam annealing los txhim kho nws cov corrosion kuj.Txawm li cas los xij, yog tias 316L stainless hlau siv, tom qab vuam annealing tsis tas yuav tsum tau.
