The 1.4501 is an austenitic-ferritic, high-alloy, low-carbon chromium-nickel-molybdenum-tungsten (super duplex) steel that is resistant to chloride-containing media and can be used in areas where traditional duplex steels are no longer adequate. Due to higher contents of chromium and molybdenum in combination with tungsten, the PREN-values of the material are from 40 to>46 J uas muaj kev cuam tshuam zoo thiab coj cov khoom lag luam tiv thaiv ntawm {}} suprosion, thiab yog qhov haum rau siv hauv sulfuric Acid .
1 {. 4501 tau teev nyob rau hauv kev faib tawm Aisi F55 raws li ANTM A182 qib qib F55 qhov qauv.

Cov ntaub ntawv kev lag luam tseem ceeb ntawm cov hlau tsis muaj ntawm lwm tus, cov tshuaj petrochemical {}}} Cov khoom noj khoom haus (cov roj ntsha tanker) .
Cov yam ntxwv
Vuam:Tus Hlau 1 . 4501 yog weldable nrog txhua cov txheej txheem (TIG VUAM, SUBMER, DUA} Qhov kev zam yog roj-yaj vuam! Muaj kev pheej hmoo ntawm intermetallic tebchaw interounds.}} Txawm li cas los xij, ib qho kev hloov pauv hauv thaj chaw uas muaj qhov chaw weld tau tso tseg (thaj chaw kub).
Forging:Ua ntej kev zam, cov hlau yuav tsum tau rhuab rau 1150℃rau 1180 Degree. Cov txheej txheem SUCTANS. Cov txheej txheem actuantant {1.4501.
Machining:Machin yuav tsum tau nqa tawm hauv kev daws cov kev daws teeb meem, nrog kev tsis tshua muaj cua sov (}20-40
Corrosion Kuj:This stainless steel has a very good corrosion resistance. Use in media causing pitting or stress corrosion cracking is possible because tungsten increases pitting resistance. The PREN values (chromium sum) can be>40 raws li kev soj ntsuam tshuaj .
Polishing:Vim yog ob-theem ferrite-Austenite qauv qauv, lub txiaj ntsig polishing txawv tus yam ntxwv ntawm cov khoom pauv no .
2. kev kho cua sov
Kev kho cua sov ntawm 1 {. 4501 yog nqa tawm los ntawm kev daws teeb meem sai nyob rau hauv cov dej txias hauv cov dej txaus thiab qhov no tseem pom zoo tom qab vuam cross loj dua.
