log tsheb hloov & kho
Ob leeg 316 thiab 316L stainless hlau kav yog ruaj khov, corrosion-resistant alloys. 316L yog tsawg- carbon version, ua rau nws tsim nyog rau vuam daim ntawv thov vim nws zoo heev weldability thiab kuj rau intergranular corrosion. Ua tsaug rau qhov sib ntxiv ntawm molybdenum, ob qib zoo - haum rau siab - chloride raug ib puag ncig, xws li marine applications, thiab muaj ntau yam kev siv hauv kev lag luam thiab kev huv. Qhov sib txawv tseem ceeb nyob rau hauv cov ntsiab lus carbon, uas cuam tshuam rau txhua yam khoom xws li tensile lub zog; 316 feem ntau muaj me ntsis siab dua tensile zog tshaj 316L.
Puas yog 316 stainless hlau zoo dua rau siab - qhov kub thiab txias dua li 316L stainless hlau?
Thaum tshav kub kub Resistance: 316L stainless hlau yog ntau resistant rau carbide nag lossis daus tshaj tus qauv 316 thiab 316H stainless hlau thiab yuav siv tau nyob rau hauv lub aforementioned kub ntau yam. Txawm li cas los xij, rau cov ntawv thov uas xav tau siab dua - qhov kub thiab txias, yuav tsum muaj cov ntsiab lus carbon ntau dua.
Dab tsi yog 316 thiab 316L stainless hlau?
316 thiab 316L stainless hlau yog austenitic stainless hlau, feem ntau muaj hlau, chromium, npib tsib xee, thiab molybdenum. Qhov sib ntxiv ntawm molybdenum (2-3%) txhim kho lawv cov corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj chloride. Qhov sib txawv tseem ceeb ntawm 316 thiab 316L stainless hlau nyob hauv lawv cov ntsiab lus carbon:
316 stainless hlau muaj qhov siab tshaj plaws carbon cov ntsiab lus ntawm 0.08%.
316L stainless hlau ("L" sawv cev rau cov pa roj carbon tsawg) muaj cov ntsiab lus siab tshaj plaws ntawm 0.03%, uas txo cov carbide nag lossis daus thaum vuam, yog li txhim kho weldability.
Ob leeg stainless hlau muaj zoo heev mechanical zog thiab corrosion kuj, tab sis nyob rau hauv kev lag luam uas yuav tsum tau welding los tiv thaiv intergranular corrosion, 316L stainless hlau kav yog ib tug superior xaiv.
