Nws cov pa roj carbon qis tiv thaiv qhov tsis txaus ntseeg thiab kev xaiv weldability, nrog rau kev siv tau cov tshuaj, kev kub ntxhov, thiab ib puag ncig marrine.
ASTM A312 Tp336?
A312 TPOR36 yog Austenicial Stainless hlau Alloy. Ua los ntawm qhov siab -} zoo npib tsib xee, thiab molybdenum alloy, Astm Aloy, Astm A316 haum rau siv ntau yam kev lag luam. Cov khoom siv no muaj kev tiv thaiv zoo heev rau corrosive thiab oxidizing media hauv tshuab.
ASTM A312 TP316L (UNRST S31603) Petrochemical Seamless Stainless Hlau Yeeb Nkab
ASTM A312 TP316L (UNRENT S31603) Yog cov tshuaj ntsuab uas tsis muaj zog, kev ua haujlwm siab, roj thiab roj thiab lwm yam kev lag luam xav tau. Vim nws cov ntsiab lus carbon qis (tsawg dua los yog sib npaug rau 0.03%), cov yeeb nkab no muaj cov dej siab zoo dua piv rau lub sijhawm Vuam thiab nag lossis cua sov.

316L stainless hlau seamless yeeb nkab rau lub petrochemical kev lag luam tseem ceeb nta
Austenitic qauv: nws txoj kev ua kom muaj kev sib txuam nrog cov xwm txheej zoo thiab cov khoom siv zoo thoob plaws ntau qhov ntau.
Molybdenum Content: The addition of molybdenum imparts excellent strength to the alloy and significantly enhances its resistance to pitting corrosion in chloride-containing environments.
Cov pa roj carbon (316L): S31603 tsim cov khoom lag luam tsawg- hom carbon version (316L hom), uas txhim kho kev tiv thaiv corrosion (316L hom) tom qab kev tiv thaiv kev sib tw carbide nag lossis daus.
Corrosion Kuj: piv rau lwm qib xws li 304, nws ua kom pom tseeb zoo rau General corrosion thiab pitting corrosion, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj tua kab mob thiab cov tub rog ua haujlwm.
Weldability: cov ntsiab lus carbon qis ua rau nws yooj yim rau weld, tshem tawm cov kev xav tau rau postne- weld annealing los kho corrosion tsis kam.
Cryogenic Performance: Cov khoom siv Austenitic lub teeb tsa ua kom nws ua tau zoo txawm tias muaj qhov kub tsawg heev.
Kev Siv Petrochemical Kev Lag Luam Petro
Tshuaj lom neeg txheej txheem piping: nws cov kev tiv thaiv zoo heev rau ntau yam ntawm cov tshuaj corrosive, suav nrog cov muaj tshuaj tsw qab, tshuaj dawb, ua rau nws xaiv cov txheej txheem.
High -} Qhov kev siv kub: nws muaj peev xwm tswj tau kub zog thiab nkag rau ntau yam kev siv rau hauv cov nroj tsuag.
Marine ib puag ncig: nws zoo pitting tiv taus ua rau nws zoo -}} haum rau cov tubrog nkoj lossis chloride- Cov dej ib puag ncig.
Welded Cheebtsam: Vim nws txoj kev txhim kho weldability thiab tsis kam mus rau qhov tsis txaus ntseeg, nws yog dav siv nyob rau hauv tuab {}}} teev cia peb welded Cheebtsam.
