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, tso cai rau kev txo qhov hnyav thiab cov ntu nyias nyias hauv cov qauv siv.

Tus nqi -zoo:Tsawg nickel thiab molybdenum cov ntsiab lus, ua ke nrog manganese thiab nitrogen alloying, muab kev ua tau zoo ntawm tus nqi qis dua thiab ruaj khov dua li cov pa hlau tsis zoo.

Zoo Corrosion Resistance:Muab kev tiv thaiv corrosion piv rau 304L hauv ntau qhov chaw, nrog kev ua haujlwm zoo rau kev ntxhov siab corrosion tawg vim nws cov qauv duplex.

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.

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 zoo pitting kuj (PREN 25-26 vs. 304L's 18-20) thiab zoo dua rau kev nyuaj siab corrosion cracking. Nws yog magnetic, thaum 304L tsis yog{15}}magnetic. LDX 2101 feem ntau yog tus nqi-zoo thiab tus nqi ruaj khov vim nws cov ntsiab lus qis nickel. 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 feem ntau yog xaiv rau cov qauv siv uas muaj zog thiab kev lag luam yog qhov tseem ceeb.

 

Dab tsi yog qhov kev txiav txim siab vuam rau LDX 2101 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 kuj tseem siv tau rau cov ntawv thov tsawg dua. Cov ntsiab lus nitrogen siab thiab manganese stabilization txo qhov kev pheej hmoo ntawm hydrogen-induced cracking thiab kub tawg. Kev pom zoo cua sov tawm tswv yim yog 0.5-2.5 kJ / mm, nrog kev sib tshuam kub hauv qab 150 degree. Tiv thaiv roj 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 vuam 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.
