1.4501 Stainless hlau yog dab tsi?

1.4501 stainless hlau, dav paub los ntawm nws lub npe lag luam Zeron 100 (thiab kuj yog UNS S32760 lossis F55), yog super duplex stainless hlau txhim kho nrog tungsten thiab tooj liab. Nws sawv cev rau qhov siab tshaj plaws ntawm duplex alloys, muab kev sib xyaw ua ke ntawm lub zog loj, tshwj xeeb corrosion tsis kam-tshwj xeeb tshaj yog tiv thaiv pitting thiab kev ntxhov siab corrosion cracking- thiab txhim kho weldability. Qhov sib ntxiv ntawm tungsten thiab tooj liab muab kev ua tau zoo tshaj plaws nyob rau hauv ib puag ncig hnyav, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov kev xav tau tshaj plaws ntawm ntug dej hiav txwv, tshuaj, thiab subsea daim ntaub ntawv.

 

Qhov hwm super duplex qib no tau txhais raws li cov qauv tseem ceeb thoob ntiaj teb.

Cov yam ntxwv tseem ceeb thiab kev siv ntawm 1.4501 / Zeron 100

Tsis sib haum Corrosion Resistance:Muaj tus lej tshwj xeeb siab Pitting Resistance Equivalent Number (PREN> 40), muab qhov zoo tshaj plaws - hauv -chav kawm tiv thaiv pitting, crevice corrosion, thiab kev ntxhov siab corrosion tawg hauv kub, chloride-laden ib puag ncig. Qhov ntxiv tungsten ntxiv txhim kho pitting tsis kam ntawm qhov kub siab.

Muaj zog heev:Muab lub zog tawm los kwv yees li ob npaug ntawm cov qauv austenitic steels, ua kom muaj qhov hnyav thiab txo nqi hauv cov hlab ntsha siab thiab cov khoom siv.

Txhim kho Weldability:Qhov sib npaug sib npaug, suav nrog tungsten thiab tooj liab, txhawb kev ruaj khov microstructure nyob rau hauv welds, ua rau nws ntau zam txim rau weld dua li lwm cov qib super duplex nrog zoo corrosion kuj.

Kev Pab Cuam Zoo Tshaj Plaws:Kev ua tau zoo hauv H₂S- muaj ib puag ncig, ua rau nws zoo tagnrho rau kev siv roj thiab roj.

 

Cov ntawv thov tseem ceeb:

Subsea & Offshore:Christmas ntoo, manifolds, flowlines, risers, thiab umbilicals nyob rau hauv dej tob thiab roj ntau lawm.

Tshuaj & Txheej Txheem:Reactors, kem, kub exchangers, thiab piping tuav nruj sib tov ntawm acids, chlorides, thiab lwm yam corrosive media.

Pollution Control:FGD scrubbers, absorber towers, thiab tseem ceeb ductwork hauv fais fab nroj tsuag desulfurization systems.

Pulp & Ntawv:High -siab thiab siab - kub diesters thiab bleaching khoom.

Marine Engineering:Lub tshuab nqus tsev twj tso kua mis, lub twj tso kua mis seawater, thiab valve systems.

Zeron 100 (1.4501) txawv ntawm Super Duplex 2507 (1.4410) li cas?
Thaum ob qho tib si yog qib super duplex, Zeron 100 muaj cov ntsiab lus alloying ntxiv -tungsten (W) thiab tooj liab (Cu)- uas 2507 tsis ua. Tungsten ntxiv txhim khu pitting thiab crevice corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv siab kub, thiab txhim kho stability ntawm lub microstructure thaum vuam los ntawm retarding lub tsim ntawm detrimental intermetallic theem. Tooj liab txhim khu kev tiv thaiv kom tsis txhob muaj cov kua qaub xws li sulfuric acid. Qhov no muab Zeron 100 qhov kev ua tau zoo nyob rau hauv qhov nyuaj tshaj plaws thiab hnyav corrosive ib puag ncig, tshwj xeeb tshaj yog cov uas muaj cov chlorides thiab acids, lossis qhov chaw ua haujlwm siab dua. Nws kuj tseem muaj kev txhim kho toughness ntawm qhov kub thiab txias zoo dua rau sulfide kev ntxhov siab tawg hauv kev pabcuam qaub.

 

Dab tsi ua rau vuam Zeron 100 txawv ntawm vuam txheej txheem duplex steels?
Vuam Zeron 100 ua raws li cov hauv paus ntsiab lus zoo sib xws (tswj cov khoom siv hluav taws xob, siv ntau tshaj -alloyed muab tub lim) tab sis tau txais txiaj ntsig los ntawm nws cov khoom muaj txiaj ntsig zoo. Cov ntsiab lus tungsten pab tiv thaiv qhov tsim ntawm kev cuam tshuam ntawm intermetallic theem (sigma, chi) nyob rau hauv tshav kub- cuam tshuam cheeb tsam (HAZ), muab qhov dav "qhov rais ua haujlwm" thiab txo qhov kev pheej hmoo ntawm embrittlement. Kev pom zoo cua sov yog feem ntau 0.5-2.0 kJ/mm, nrog rau qhov kub thiab txias hauv qab 150 degree. Cov hlau sib xyaw ua ke (xws li Zeron 100X) muaj, lossis tshaj -cov khoom siv nickel-raws li alloyed yuav raug siv rau kev tiv thaiv corrosion siab tshaj. Nws tseem yuav tsum tau ua tib zoo saib xyuas cov txheej txheem tsim nyog tab sis feem ntau suav hais tias muaj qhov zoo dua weldability dua li lwm cov super duplex alloys zoo li corrosion kuj, ua rau nws ntau zam txim rau hauv fabrication.
