1. Lo Lus Nug: Cov tshuaj lom neeg muaj pes tsawg leeg ntawm inconel 825?
Teb: Inconel 825 yog ib npib tsib xee-} roj chomium alloy nrog ntxiv cov ntsiab lus los txhim kho corrosion tsis kam. Nws cov ntawv cim raug suav nrog:
NI: 38-46%
FE: 38% Ntau
Cr: 19.5-23.5%
MO: 2.5-3.5%
Cu: 1.5-3%
Me me ntawm C, MN, si, ti, thiab al
Qhov kev sib xyaw ua ke muab cov kev zam tshwj xeeb rau oxidation, acids, thiab dej hiav txwv corrosion.
2. Lo lus nug: Dab tsi yog cov ntawv thov tseem ceeb ntawm alloy 825 daim hlau thiab cov ntawv txheeb?
Teb: Alloy 825 tau siv dav hauv kev lag luam uas xav tau kev ua siab loj, xws li:
Cov khoom siv tshuaj lom neeg (cov tshuaj tiv thaiv, kev hloov cua sov, tso tsheb hlau luam)
Acidic ib puag ncig, suav nrog sulfuric, hydrochloric, thiab phosphoric acids
Roj thiab roj pipelines, tshwj xeeb hauv cov chaw puag ncig
Marine Engineering Thiab Desalination Nroj Tsuag
Flue Roj Desulfurization Chav Nyob
3. Lo lus nug: Yuav ua li cas inconel 825 ua hauv kev xeb ib puag ncig?
Teb: Inconel 825 tau ua rau muaj kev tiv thaiv zoo heev rau:
Pitting thiab crevice corrosion nyob rau hauv chloride -} muaj cov kev daws teeb meem
Kev ntxhov siab corrosion tawg
Oxidation thiab sulfidation ntawm qhov kub
Nws yog qhov haum rau ob qho tib si oxidizing thiab txo cov khoom siv tshuaj lom neeg, ua rau nws zoo dua rau cov qauv stainless hlau hauv kev tawm tsam.
4. Lo lus nug: Dab tsi yog cov khoom siv tshuab ntawm alloy 825 cov ntawv thiab daim hlau?
Teb: Alloy 825 tswj lub zog zoo thiab ductility ntau tshaj qhov kub thiab txias:
Lub zog tensile: 515-827 mpa
Yield zog: 205-380 MPA
Elongation: 30-50%
Hardness (Brinell): 150-200 HB
Cov khoom muaj tseeb kom ntseeg tau tias kev ua tau zoo hauv high - muaj kev ntxhov siab thiab siab- kev siv kub.
5. Lus Nug: Tau Alloy 825 yuav welded thiab fab yooj yim?
Teb: Yog, Alloy 825 yog yooj yim muabricated thiab welded siv cov txheej txheem pa:
Tige, Mig, thiab Arc Vuam nrog Alloy 825 Cov Quav Muab Cov Quav Pom Zoo
Preheating feem ntau tsis tas yuav tsum tau
Machining yog ncaj nrog cov cuab yeej tsim nyog, txawm hais tias alloy txoj kev nruj yuav xav tau qeeb qeeb txiav ceev
Post - Weld annealing yog feem ntau tsis tsim nyog rau kev tswj hwm corrosion tsis kam
