Puas yog AISI 316 zoo ib yam li SS 316?
AISI 316 thiab SS 316 yog, qhov tseem ceeb, tib yam khoom; ob leeg sawv cev tib qib ntawm austenitic stainless hlau nrog molybdenum cov ntsiab lus. "AISI" (American Iron and Steel Institute) yog lub cev qauv, thaum "SS" yog cov ntawv luv ntawm * Stainless Hlau *; Yog li, "SS 316" feem ntau yog siv los ua ib txoj hauv kev luv luv rau AISI 316. AISI 316 muaj 16% chromium, 10% nickel thiab 2% molybdenum, thaum SS 316 muaj 18% chromium, 12% nickel thiab 2% molybdenum. Txij li thaum SS 316 muaj feem ntau ntawm chromium, nws cov corrosion kuj yog siab dua li ntawm AISI 316.

Dab tsi yog qhov txawv ntawm 316 thiab 316L stainless hlau?
Ob leeg SS316 thiab SS316L yog cov ua haujlwm siab austenitic stainless hlau uas muaj molybdenum; Qhov sib txawv tseem ceeb ntawm ob yog nyob rau hauv lawv cov ntsiab lus carbon. SS316L (qhov sib txawv ntawm cov pa roj carbon tsawg, nrog qhov feem pua tsawg dua lossis sib npaug li 0.03%) muaj kev ua tau zoo tshaj plaws hauv cov ntawv thov uas muaj cov khoom siv welded, pab tiv thaiv corrosion; thaum SS316 (qhov sib txawv nrog cov qauv carbon cov ntsiab lus, nrog rau feem pua tsawg dua lossis sib npaug li 0.08%) muaj zog dua me ntsis thiab hardness.
Corrosion kuj ntawm 316 thiab 316L stainless hlau kav
Ob leeg 316 thiab 316L stainless hlau kav muaj kev tiv thaiv corrosion zoo heev, tshwj xeeb tshaj yog tiv thaiv chlorides thiab hauv marine ib puag ncig, vim lawv cov ntsiab lus 2-3% molybdenum. 316L (cov pa roj carbon tsawg) feem ntau yog qhov zoo tshaj plaws vim nws tiv thaiv kev nkag siab thiab kev cuam tshuam ntawm intergranular tom qab vuam. Thaum 316 muaj zog dua me ntsis, 316L tiv thaiv carbide nag lossis daus, ua rau nws tsim nyog rau kev siv vuam hauv qhov chaw muaj corrosive heev.
Dab tsi yog qhov ceev ntawm 316 thiab 316L stainless hlau kav?
Qhov ntom ntawm 316 thiab 316L stainless hlau yeeb nkab yog kwv yees li 8.0 g / cm³ (0.289-0.290 lb / in³ lossis 8000 kg / m³). Qhov ceev tas li no siv tau rau ob qib, ua rau lawv xaiv zoo heev rau qhov chaw muaj corrosive xws li marine, tshuaj thiab zaub mov siv.
316 thiab 316L stainless hlau kav: Yuav xaiv li cas?
Xaiv 316L stainless hlau yeeb nkab rau superior corrosion kuj nyob rau hauv welded daim ntaub ntawv -xws li tshuaj ua, marine ib puag ncig thiab tshuaj tshuab- vim nws tsis tshua muaj carbon cov ntsiab lus (0.03% max), uas tiv thaiv corrosion nyob rau hauv lub tshav kub cuam tshuam cheeb tsam ntawm lub vuam. Xaiv tus qauv 316 rau nws lub zog siv tshuab ntau dua hauv kev siv cov txheej txheem kub kub lossis cov uas tsis tas yuav tsum tau vuam.
Yog tias koj muaj cov cai tshwj xeeb rau koj qhov project hais txog 316L stainless hlau kav, koj tuaj yeem txais tos koj xaj. GNEE khaws cov ntaub ntawv tseem ceeb ntawm cov khoom nrov rau koj xaiv. Muaj nyob rau hauv ob qho tib si seamless thiab welded versions, peb cov khoom tuaj yeem ua raws li koj qhov tshwj xeeb.
