Gnee Steel (Tianjin) Co., Ltd. yog ib tug ua thiab ntseeg siab heev manufacturers thiab tsum ntawm09CrCuSb corrosion-resistant ND steel kavhauv Suav teb.
Peb zoo siab tos txais cov neeg siv khoom los yuav cov nqi hwm- zoo 09CrCuSb ND steel kav ncaj qha los ntawm peb lub hoobkas. Tag nrho cov khoom tau muab nrog kev ruaj khov zoo, kev tshuaj xyuas nruj, thiab tus nqi sib tw.
09CrCuSb seamless steel yeeb nkab, feem ntau hu ua ND steel, yog siv dav hauv cov chaw tsim hluav taws xob thiab cov roj refineries.
Nws yog tsuas yog siv rau kev tsim khoom lag luam, cua preheaters, cua sov hloov pauv, thiab cov evaporators ua haujlwm nyob rau hauv high -sulfur flue gas ib puag ncig.
Cov Cheebtsam no yog tsim los tiv thaiv condensation corrosion thiab sulfur -muaj flue gas yaig.

Cov khoom siv
09CrCuSb seamless steel kav yog siv dav hauv kev tsim cov khoom lag luam, cua preheaters, hloov hluav taws xob, thiab cov evaporators raug rau siab - cov roj sulfur flue gas.
Cov khoom muaj kev tiv thaiv zoo rau qis -kub sulfuric acid dew point corrosion, tshwj xeeb tshaj yog kub hauv qab 200℃. Raws li qhov tshwm sim, 09CrCuSb ND steel yog suav tias yog ib qho niaj hnub, ib puag ncig tus phooj ywg, thiab lub zog -kev xeb zoo- cov khoom siv tiv taus.
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.
