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.
