1.4563 Stainless hlau yog dab tsi?

1.4563 stainless hlau, feem ntau hu ua Alloy 25-6Mo lossis UNS S32053, yog super austenitic stainless hlau nrog siab chromium, nickel, molybdenum, thiab nitrogen cov ntsiab lus. Nws yog tsim los rau tshwj xeeb tsis kam rau pitting, crevice corrosion, thiab kev nyuaj siab corrosion cracking nyob rau hauv hnyav chloride ib puag ncig, ua rau nws tsim nyog rau kev thov nyob rau hauv offshore, tshuaj ua, thiab desalination industries.

 

Qhov siab -kev ua tau zoo super austenitic qib no yog tus qauv raws li cov qauv tseem ceeb thoob ntiaj teb.

Txuj	Qib sib npaug
EN (Tebchaws Europe)	1.4563
ASTM / AISI (USA)	Alloy 25-6Mo, UNS S32053
Lub Npe	Alloy 25-6Mo, S32053

Nws cov ntsiab lus siab alloy, tshwj xeeb tshaj yog molybdenum thiab nitrogen, yog qhov tseem ceeb rau nws cov corrosion kuj.

Element	C	Si	Mn	P	S	Cr	Ni	Mo	N
Cov ntsiab lus (%)	Tsawg dua lossis sib npaug li 0.03	Tsawg dua los yog sib npaug li 0.8	Tsawg dua los yog sib npaug rau 2.0	Tsawg dua lossis sib npaug li 0.03	Tsawg dua lossis sib npaug li 0.01	24.0 - 26.0	21.0 - 24.0	6.0 - 7.0	0.20 - 0.35

Nws muaj lub zog siab thiab zoo heev ductility nrog rau superior corrosion kuj.

Tus nqi	Ntau tshaj lossis sib npaug li 300 MPa	650 - 850 MPa	Ntau dua lossis sib npaug li 35%	Tsawg dua los yog sib npaug li 250

 

Cov yam ntxwv tseem ceeb thiab kev siv ntawm 1.4563 / Alloy 25-6Mo

Exceptional Pitting thiab Crevice Corrosion Resistance:Nrog rau PREN (Pitting Resistance Equivalent Number)> 40, nws muaj kev tiv thaiv zoo tshaj hauv cov tshuaj chloride ib puag ncig, nrog rau cov dej hiav txwv kub thiab cov dej brine.

Zoo heev Stress Corrosion Cracking (SCC) Resistance:Ua tau zoo nyob rau hauv tensile kev nyuaj siab nyob rau hauv corrosive ib puag ncig uas lwm yam austenitic qib yuav poob.

Zoo Weldability thiab Formability:Yuav tau welded siv cov txheej txheem ntau thiab nthuav tawm cov ductility zoo rau kev ua haujlwm.

 

Cov ntawv thov tseem ceeb:

Seawater Desalination:Rov qab osmosis (RO) daim nyias nyias, siab - cov kav dej siab, thiab cov raj evaporator.

Offshore & Marine:Thaum tshav kub kub exchangers, twj, valve, thiab subsea Cheebtsam.

Kev ua tshuaj lom neeg:Cov khoom siv los tuav cov kua qaub, chlorides, thiab oxidizing media.

Pollution Control:FGD (Flue Gas Desulfurization) systems thiab scrubbers.

 

Alloy 25-6Mo (1.4563) piv rau 254 SMo (1.4547) li cas?
Ob leeg yog qib super austenitic, tab sis Alloy 25-6Mo muaj cov qib chromium thiab npib tsib xee ntau dua, muab nws zoo dua rau kev tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig acid-chloride sib xyaw. Nws kuj muaj me ntsis siab dua mechanical zog. Alloy 25-6Mo feem ntau raug xaiv rau kev siv corrosive hnyav dua qhov twg ob qho tib si pitting tsis kam thiab dav dav corrosion kuj tseem ceeb heev.

 

Dab tsi yog qhov kev txiav txim siab vuam rau Alloy 25-6Mo stainless hlau?
Vuam Alloy 25-6Mo yuav tsum tau ceev faj tswj kom muaj kev tiv thaiv corrosion. Cov kev coj ua uas pom zoo suav nrog kev siv qhov sib txuam lossis ntau dua - cov hlau alloyed muab tub lim (xws li Alloy 625 lossis siab dua-qib austenitic fillers), tswj cov cua sov kom tsis txhob muaj qhov sib txuam ntau dhau, thiab ua kom muaj kev tiv thaiv kom tsis txhob muaj nitrogen. Kev ntxuav tom qab vuam yog qhov tseem ceeb los tiv thaiv corrosion hauv cheeb tsam weld.
