1.4662 Stainless hlau yog dab tsi?

1.4662 stainless hlau, feem ntau hu ua 2001 los yog UNS S32001, yog ib tug lean duplex stainless hlau tsim los muab kev pom zoo sib npaug ntawm lub zog siab, zoo corrosion kuj, thiab kev lag luam zoo heev. Nrog nws cov ferritic -austenitic microstructure, nws muab kwv yees li ob npaug ntawm cov khoom muaj zog ntawm cov pa austenitic qib zoo li 304L, thaum siv cov ntsiab lus nickel thiab molybdenum txo qis heev. Qhov no ua rau nws tus nqi tshwj xeeb- siv tau zoo rau cov ntawv thov uas tsis tas yuav muaj cov ntsiab lus siab dua ntawm cov qauv duplex.

Cov yam ntxwv tseem ceeb thiab kev siv ntawm 1.4662 / 2001

Siab zog:Muab kwv yees li ob npaug ntawm qhov muaj zog ntawm cov qib austenitic zoo li 304L, ua kom txo qis qhov hnyav thiab cov ntu nyias nyias hauv cov qauv siv.

Kev lag luam zoo heev:Tsis tshua muaj nickel thiab molybdenum cov ntsiab lus, ua ke nrog manganese thiab nitrogen alloying, muab kev ua tau zoo ntawm tus nqi sib tw thiab ruaj khov.

Zoo Corrosion Resistance:Muab kev tiv thaiv corrosion mus txog ntawm 304L hauv ntau qhov chaw, nrog PREN feem ntau 22-24. Zoo tiv thaiv kev ntxhov siab corrosion tawg vim duplex qauv.

Zoo Weldability:Yuav tau welded siv cov txheej txheem ntau yam tsis muaj preheating, nrog zoo tiv thaiv hydrogen -induced cracking.

 

Cov ntawv thov tseem ceeb:

Structure Engineering:Txuas hniav, tso tsheb hlau luam, silos, thiab architectural lug xav kom muaj zog thiab kev lag luam.

Kev thauj mus los:Tsheb thauj mus los, tsheb ciav hlau wagons, shipping thawv, thiab tsheb ncej.

Kev kho dej:Tank, kav dej, thiab cov khoom siv hauv cov chaw kho dej thiab cov dej khib nyiab.

Kev ua zaub mov:Cov khoom siv rau kev tuav cov zaub mov qhov twg kev lag luam thiab kev txhim kho corrosion kuj tseem ceeb.

Mining thiab Mineral Processing:Cov ntxaij vab tshaus, conveyors, thiab cov khoom siv tuav.

Architectural:Cov vov tsev, cladding, thiab cov qauv kev txhawb nqa nyob rau hauv tsis yog - ib puag ncig tseem ceeb.

 

2001 (1.4662) piv rau 304L (1.4307) li cas?
2001 muaj kwv yees li ob npaug ntawm cov khoom siv zog ntawm 304L (450 MPa vs . 200 MPa), ua kom cov khoom hnyav hnyav thiab cov khoom siv nyias nyias. Nws qhov kev tiv thaiv corrosion yog nce mus txog ntawm 304L hauv ntau qhov chaw, nrog PREN 22-24 piv rau 304L's 18-20, muab piv los yog zoo dua pitting tsis kam. Nws muab kev tiv thaiv zoo dua rau kev ntxhov siab corrosion tawg vim nws cov qauv duplex . 2001 yog tus nqi ntau dua - zoo thiab tus nqi ruaj khov vim nws cov ntsiab lus nickel tsawg heev. Nws yog sib nqus, thaum 304L tsis yog hlau nplaum. Txawm li cas los xij, 304L muaj kev tsim tau zoo dua rau cov duab nyuaj thiab muaj zog dua ntawm qhov kub thiab txias heev . 2001 yog qhov kev xaiv zoo tshaj plaws rau kev siv cov qauv uas muaj zog thiab kev lag luam yog thawj tsav tsheb.

 

Dab tsi yog qhov kev txiav txim siab vuam rau xyoo 2001 (1.4662) stainless hlau?
2001 muaj qhov zoo weldability thiab tuaj yeem welded siv txhua txoj hauv kev yam tsis muaj preheating. Cov hlau sib xyaw ua ke muaj, txawm tias austenitic fillers (308L, 309L) kuj tseem siv tau rau cov ntawv thov tsawg dua. Cov qauv duplex muab kev tiv thaiv zoo rau kub tawg. Kev pom zoo cua sov yog 0.5-2.5 kJ / mm, nrog rau qhov kub thiab txias hauv qab 150℃kom tsis txhob muaj ferrite ntau dhau. Tiv thaiv roj nrog nitrogen ntxiv (feem ntau Ar + 2% N2) pab tswj cov ntsiab lus nitrogen hauv cov hlau vuam. Cov ntsiab lus lean alloy ua rau nws zam ntau dua rau kev vuam ntau dua- qib alloyed duplex, nrog zoo heev li -welded zog yam tsis muaj kev kho cua sov tom qab vuam. Rau qhov zoo tshaj plaws corrosion ua tau zoo, txuam cov hlau muab tub lim raug pom zoo.
