Alloy C-4 alloy yog nickel-chromium-molybdenum alloy nrog zoo heev
high-temperature stability raws li pov thawj los ntawm siab ductility thiab corrosion kuj txawm
Tom qab kev laus ntawm 1200 txog 1900 F (649 txog 1038 C) ntau. Qhov no alloy resists tsim
ntawm grain- ciam teb precipitates nyob rau hauv weld tshav kub-cuam tshuam cheeb tsam, yog li ua rau nws haum
rau feem ntau cov txheej txheem tshuaj siv nyob rau hauv cov mob as-welded. C-4 alloy tseem
Nws muaj kev tiv thaiv zoo rau kev ntxhov siab-corrosion tawg thiab oxidizing cua mus txog
1900 F (1038 C).

 

Alloy C-4 alloy muaj qhov tshwj xeeb ua haujlwm rau ntau yam txheej txheem tshuaj
ib puag ncig. Cov no muaj xws li kub paug cov ntxhia acids, cov kuab tshuaj, chlorine
thiab chlorine contaminated media (organic thiab inorganic), chlorine qhuav, formic thiab
acetic acids, acetic anhydride, thiab seawater thiab brine daws.
Alloy C-4 alloy tuaj yeem forged, kub-cuam tshuam, thiab cuam tshuam extruded. Txawm tias cov
alloy nyhav ua hauj lwm-harden, nws muaj peev xwm ua tau zoo sib sib zog nqus-draw, spun, nias tsim los yog
xuas nrig ntaus. Tag nrho cov txheej txheem ntawm kev vuam tuaj yeem siv los vuam Alloy C-4
alloy, txawm hais tias cov txheej txheem oxy-acetylene thiab submerged arc tsis pom zoo
thaum cov khoom fabricated yog npaj rau siv nyob rau hauv kev pab cuam corrosion. Kev ceev faj tshwj xeeb
yuav tsum tau noj kom tsis txhob muaj cua sov ntau dhau.
