2205 stainless hlau vs 316 nqi
Tso lus
Hauv kev lag luam uas muaj zog thiab corrosion kuj tseem ceeb heev tab sis tus nqi kuj yog ib qho kev txiav txim siab, 2205 duplex stainless hlau feem ntau yog cov khoom nyiam tshaj plaws . 2205 stainless hlau muaj cov ntsiab lus qis nickel (kwv yees li 4.5-6%) tab sis siab dua chromium thiab molybdenum cov ntsiab lus, ua rau nws kim dua. Hauv qhov sib piv, 316 stainless hlau, uas muaj cov qauv austenitic thiab muaj 16-18% nickel thiab 2-3% molybdenum, tsis tshua kim.
Dab tsi yog2205 stainless hlau?
2205 stainless hlau yog duplex (austenitic / ferritic) alloy nrog lub zog siab thiab zoo heev corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig chloride. Nws muaj kev tiv thaiv zoo tshaj plaws rau pitting, crevice corrosion, thiab kev ntxhov siab corrosion cracking, ua rau nws zoo tagnrho rau marine, roj thiab roj, thiab tshuaj siv tshuaj uas 300 series stainless hlau tsis txaus. Nws qhov kev ua tau zoo tshaj tus qauv austenitic stainless hlau, tab sis nws txoj kev siv yog txwv rau qhov kub qis dua 300℃(600℃F) kom tsis txhob embrittlement.
Dab tsi yog 316 stainless hlau?
316 stainless hlau yog molybdenum -muaj austenitic stainless hlau. Nws cov khoom tseem ceeb yog chromium (Cr), nickel (Ni), thiab molybdenum (Mo). Nws muaj kwv yees li 2-3% molybdenum ntau dua li 304 stainless hlau, uas ua rau muaj kev tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj chloride (xws li dej hiav txwv) thiab acidic ib puag ncig. Nws tseem muaj lub zog kub kub zoo, machinability, thiab weldability. Feem ntau hu ua "marine qib" los yog "qib phais" stainless hlau, nws yog dav siv nyob rau hauv chemical, kho mob, marine engineering, zaub mov, thiab corrosive ib puag ncig.

Vim li cas 2205 stainless hlau kim dua 316 stainless hlau?
2205 duplex stainless hlau yog kim dua 316 stainless hlau vim 2205 muaj cov txheej txheem tsim ntau dua (yuav tsum muaj kev tswj xyuas meej ntawm 50-50 ferrite-austenite duplex qauv, ua raws li 1020-1100℃tshuaj annealing + dej quenching). Nyob rau lub Kaum Ob Hlis 2025, tus nqi FOB hauv Suav teb yog USD 6.8-8.2 / kg, 35-55% premium tshaj 316 stainless hlau (USD 5.2-5.8 / kg) thiab 50-80% premium tshaj 316L (USD 4.8-5.2 / kg).
Rau kev siv dej hiav txwv, cov khoom siv twg zoo dua, 2205 lossis 316?
Thaum 316 stainless hlau muaj zog tiv thaiv chloride-induced pitting thiab crevice corrosion, 2205 duplex stainless hlau yog ib qho kev xaiv zoo dua rau kev ntxhov siab corrosion cracking kuj. Nyob rau hauv ib puag ncig marine, tshwj xeeb tshaj yog qhov yuav tsum muaj lub zog siab thiab kev ntxhov siab corrosion, 2205 feem ntau yog tus nqi ntau dua -.
Puas tuaj yeem 2205 stainless hlau hloov 316 stainless hlau hauv txhua daim ntawv thov?
