316/316L qib stainless hlau specifications
Ob leeg 316 thiab 316L stainless hlau yog austenitic stainless hlau. Vim muaj cov molybdenum, lawv muaj kev tiv thaiv corrosion zoo heev (tshwj xeeb tshaj yog tiv thaiv chloride corrosion). Qhov sib txawv tseem ceeb ntawm lawv yog nyob rau hauv lawv cov ntsiab lus carbon: 316L (tsawg carbon) muaj cov ntsiab lus siab tshaj plaws ntawm 0.03%, muab qhov zoo tshaj plaws weldability thiab tsis kam rau sensitization; thaum tus qauv 316 muaj cov ntsiab lus siab tshaj plaws ntawm 0.08%, muab lub zog zoo me ntsis thiab siab - qhov kub thiab txias, tab sis yuav tsum tau ceev faj ntau dua cov txheej txheem vuam. Ob leeg yog marine- qib stainless hlau, muaj cov qib siab ntawm chromium, nickel, thiab molybdenum. Lawv qhov sib txawv tseem ceeb yog cov ntsiab lus carbon, uas ua rau muaj qhov sib txawv ntawm lawv cov khoom siv kho tshuab (xws li, 316 muaj zog dua me ntsis) thiab cov yam ntxwv vuam.
Dab tsi yog 316L stainless hlau?
316L stainless hlau yog tsawg-carbon, molybdenum- muaj cov austenitic stainless hlau paub txog nws cov corrosion kuj zoo heev, tshwj xeeb tshaj yog nyob rau hauv chloride (xws li dej hiav txwv) thiab acidic ib puag ncig. Nws yog vim li no suav tias yog "marine qib" stainless hlau thiab dav siv hauv kev kho mob, zaub mov, tshuaj, thiab kev siv dej hiav txwv. Lub "L" nyob rau hauv 316L stands rau cov ntsiab lus uas tsis muaj carbon (ntau tshaj 0.03%), uas txhim kho weldability thiab tiv thaiv rhiab heev (carbide nag lossis daus) thaum vuam, muab nws superior corrosion kuj piv rau tus qauv 316 stainless hlau.
316/316L yog ib hom stainless hlau, muaj nyob rau hauv molybdenum-muaj cov tsev neeg austenitic stainless hlau. Qib no muaj cov ntsiab lus ntau dua nickel thiab molybdenum, muab nws zoo dua tag nrho corrosion tsis kam tshaj 304 stainless hlau, tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm tsis kam mus pitting thiab crevice corrosion nyob rau hauv chloride ib puag ncig. Tsis tas li ntawd, 316/316L alloy qhia tau zoo heev -kub tensile lub zog, creep zog, thiab kev nyuaj siab tawg lub zog, nrog rau zoo heev formability thiab weldability. 316L yog ib tug tsawg- carbon version ntawm 316 thiab tsis muaj sensitization; yog li ntawd, nws yog feem ntau siv nyob rau hauv tuab -walled welded Cheebtsam.

Lub ntsiab sib txawv thiab daim ntawv thov
316L (Low Carbon): Vim nws cov ntsiab lus carbon tsawg, nws tiv thaiv carbide nag lossis daus, yog li tswj kev tiv thaiv corrosion hauv tshav kub- thaj tsam cuam tshuam. Yog li ntawd, nws yog cov khoom siv zoo tshaj plaws rau cov qauv welded (cov kav dej, tso tsheb hlau luam).
316 (Standard Hom): Nws muaj lub zog zoo me ntsis thiab siab - qhov kub thiab txias ua haujlwm tshaj 316L, tab sis vuam yuav tsum tau ceev faj tuav (kev daws teeb meem annealing) kom tsis txhob hnov qab.
Corrosion Resistance: Piv nrog rau 304 stainless hlau, ob hom stainless hlau muaj zog corrosion kuj rau chlorides thiab acidic ib puag ncig, tab sis 316L yog ntau haum rau welded marine daim ntaub ntawv.
