Cov yam ntxwv tseem ceeb thiab kev siv ntawm 1.4162 / LDX 2101

Siab zog:Muab kwv yees li ob npaug ntawm cov khoom muaj zog ntawm cov qib austenitic xws li 304L thiab 316L (450 MPa vs . 200 MPa), uas tso cai rau txo qhov hnyav hnyav thiab cov ntu 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 piv rau 304L hauv ntau qhov chaw, nrog PREN feem ntau 25-26. Zoo tiv thaiv kev ntxhov siab corrosion tawg vim duplex qauv.

Weldability zoo heev:Yuav tau welded siv cov txheej txheem ntau yam tsis muaj preheating, nrog zoo tiv thaiv hydrogen -induced cracking thiab txo kev pheej hmoo ntawm kub tawg.

 

Cov ntawv thov tseem ceeb:

Structure Engineering:Txuas hniav, tso tsheb hlau luam, silos, thiab architectural structures yuav tsum 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 tuav cov khoom raug puas tsuaj.

Renewable Zog:Hnub ci vaj huam sib luag thav duab, kev txhawb nqa cov qauv, thiab cov khoom siv cua turbine.

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

 

LDX 2101 (1.4162) piv rau 304L (1.4307) li cas?
LDX 2101 muaj kwv yees li ob npaug ntawm cov khoom muaj zog ntawm 304L (450 MPa vs . 200 MPa), ua kom cov khoom hnyav hnyav thiab cov khoom siv nyias nyias. Nws cov corrosion kuj yog piv rau 304L nyob rau hauv ntau qhov chaw, nrog PREN 25-26 muab me ntsis zoo pitting tsis kam tshaj 304L's PREN 18-20. Nws muab kev tiv thaiv zoo rau kev ntxhov siab corrosion tawg vim nws cov qauv duplex. LDX 2101 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 cov qauv zoo dua rau cov duab nyuaj thiab muaj zog dua ntawm qhov kub thiab txias. LDX 2101 yog qhov kev xaiv zoo tshaj plaws rau kev siv cov qauv uas muaj zog thiab kev lag luam yog thawj tus tsav tsheb, thiab qhov twg cov khoom siv hlau nplaum tau txais.

 

Dab tsi yog qhov kev txiav txim siab vuam rau LDX 2101 (1.4162) stainless hlau?
LDX 2101 muaj qhov zoo tshaj plaws weldability vim nws qhov kev ua kom zoo. Nws tuaj yeem welded siv txhua txoj hauv kev yam tsis muaj preheating. Muab cov hlau sib txuam (piv txwv li, 22.8.3.L hom) muaj, txawm tias austenitic fillers zoo li 308L lossis 309L kuj tseem siv tau rau cov ntawv thov tsawg dua. Cov ntsiab lus nitrogen siab thiab manganese stabilization muab kev ua haujlwm zoo rau hydrogen -induced cracking thiab kub tawg. Kev pom zoo cua sov yog 0.5-2.5 kJ/mm, nrog rau qhov kub thiab txias hauv qab 150 degree. Shielding gas nrog nitrogen ntxiv (feem ntau Ar + 2-3% N2) pab tswj cov ntsiab lus nitrogen hauv cov hlau vuam. Cov ntsiab lus lean alloy ua rau nws zam ntau dua rau kev sib tsoo ntau dua - qib alloyed duplex, nrog lub qhov rais ua haujlwm dav dua thiab zoo heev li -welded zog yam tsis muaj kev kho cua sov tom qab vuam.
