4. Yuav ua li cas cov alloys ua nyob rau hauv kev kub siab thiab corrosive ib puag ncig?
Teb:
Nickel Alloy 825 (Incoloy 825):
Zoo heev rau ob tus oxidizing thiab txo cov chaw ib puag ncig, tshwj xeeb tshaj yog nyob rau hauv acidic tej yam kev zoo li sulfuric thiab phosphoric acid. Nws tuaj yeem tiv thaiv kub txog 870℃(1,600℃f) thiab tseem nyob ruaj khov hauv kev txo qis, acidic tej yam kev mob.
Inconel 625:
Muaj qhov kev ua tau zoo tshwj xeeb hauv kev kub siab txog 1,000 qib (1,832℃f). Nws tiv thaiv oxidation, corrosion, thiab pitting hauv qhov chaw hnyav, suav nrog dej hiav txwv, muaj kuab lom, thiab muaj kuab lom.
Ntshiab Nickel:
Qhov zoo tshaj plaws rau cov ntawv thov uas xav tau kev tiv thaiv kom corrosion hauv alkaline thiab mob acidic ib puag ncig. Nws ua tau zoo nyob rau hauv qhov kub thiab txias txog 600℃(1,112℃f), txawm tias nws tsis zoo nyob rau hauv kev kub-oxidation li alloys zoo li inconel lossis incoloy.
5. Dab tsi yog cov vuam thiab fab ntaub ntawv txiav txim rau cov ntaub ntawv no?
Teb:
Nickel Alloy 825 (Incoloy 825):
Yuav muab welded siv cov txheej txheem ib txwm muaj xws li Tig thiab Mig. Preheating feem ntau tsis tsim nyog, tab sis tom qab kev kho cua sov sov yuav pom zoo los txhim kho cov khoom siv neeg kho tshuab thiab txo qis kev ntxhov siab.
Inconel 625:
Zoo heev weldability, feem ntau welded los ntawm Tig, Mig, lossis Laser Vuam. Preheating tsis yog feem ntau yuav tsum tau, thiab tsis muaj kev kho cua sov-weld yog qhov tsim nyog rau cov ntawv thov feem ntau. Nws yog ib qho tseem ceeb kom tsis txhob muaj cua sov ntau dhau los tswj nws txoj kev tiv thaiv kom kub oxidation heigh.
Ntshiab Nickel:
Yooj yim rau weld siv cov qauv txheem xws li Tig thiab Mig Vuam. Txawm li cas los xij, Nickel ntshiab yog cov muaj kev cuam tshuam ntau dua los tsoo, yog li nws yog qhov tseem ceeb kom tsis txhob muaj siab vuam kom sov thiab ua kom txias. Preheating thiab tom qab weld kev kho cua sov feem ntau tsis xav tau.
Cov lus nug no thiab cov lus teb muab kev nkag siab ntxaws txog Nickel Alloy 825, Incaries ua tau zoo, thiab cov ntawv sau ua kom muaj zog, txaij, thiab cov khoom lag luam phaj.
