09CrCuSb acid-cov hlau tiv taus,tseem hu ua ND steel, feem ntau hu ua 09 chromium-tooj liab-antimony steel. Cov qib no tau tsim tshwj xeeb los ua kom muaj kev ua tau zoo tiv thaiv sulfuric acid dew- taw tes corrosion, ua rau nws tsim nyog rau qhov hnyav flue gas ib puag ncig.
Nws yog siv dav hauv kev tsim cov khoom siv hluav taws xob siab ({0}}sulfur flue gas economizers, air preheaters, evaporators, heat exchangers, and related thermal equipment, where the resistance to corrosive sulfur-}muaj flue gas condensation.
Tsis tas li ntawd, 09CrCuSb acid-cov hlau tsis muaj zog ua pov thawj zoo rau cov tshuaj chloride ions thiab muab kev tiv thaiv kev tiv thaiv corrosion zoo.

Piv nrog cov pa roj carbon zoo tib yam thiab cov hlau tsis zoo, 09CrCuSb acid-cov hlau tsis muaj zog ua kom pom kev zoo dua corrosion, tshwj xeeb tshaj yog nyob rau hauv qis - kub sulfuric acid dew- cov ntsiab lus.
Peb cov khoom 09CrCuSb tau ua tiav los ntawm cov chaw tsim khoom loj thiab cov chaw tsim khoom lag luam, xa cov kev pabcuam zoo thiab tau txais cov lus pom zoo los ntawm cov neeg siv khoom.
09CrCuSb steel yog dab tsi?
09CrCuSb, tseem hu ua ND steel, yog ib qho qis - alloy corrosion- cov hlau tsis muaj zog tshwj xeeb uas tsim los siv rau hauv cov kua qaub dew point corrosion ib puag ncig. Nws muaj cov ntsiab lus alloying xws li chromium (Cr), tooj liab (Cu), thiab antimony (Sb), uas ua rau nws muaj zog tiv thaiv sulfuric acid thiab flue gas corrosion.
Vim li cas 09CrCuSb hu ua ND steel?
"ND" sawv rauNitric acid thiab Dew -point corrosion kuj. Cov hlau tau tsim los tiv thaiv qis -kub acid condensation corrosion feem ntau pom nyob rau hauv boilers, heat exchangers, thiab flue gas systems.
Puas yog 09CrCuSb steel muaj qhov zoo weldability?
Yog lawm. 09CrCuSb steel muaj qhov zoo weldability. Cov txheej txheem vuam txheej txheem xws li SMAW, SAW, thiab TIG tuaj yeem siv tau, tab sis qis - hydrogen electrodes thiab preheating kom zoo yuav raug pom zoo rau cov ntu tuab.
Puas yog 09CrCuSb haum rau siab -kev pabcuam kub?
09CrCuSb yog tsim los rau nruab nrab - qhov kub thiab txias qhov chaw uas acid dew point corrosion tshwm sim. Nws tsis yog npaj rau siab heev - qhov kub siab ntawm lub nkoj siv yam tsis muaj kev ntsuam xyuas zoo.
