SPA-C steel phaj yog lub siab -kev ua tau zoo huab cua steel tsim los tiv thaiv xeb thiab ib puag ncig kev puas tsuaj. Nws ua raws li tus qauv Japanese JIS G3125, ua kom ruaj khov thiab txhim khu kev qha.
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm SPA-C steel phaj yog nws zoo heev tiv thaiv corrosion thiab atmospheric raug. Thaum raug huab cua, qhov saum npoo ib txwm ua ib txheej tuab thiab ruaj khov oxide (patina), uas tiv thaiv cov hlau zoo los ntawm kev xeb ntxiv thiab kev puas tsuaj.
Ua tsaug rau qhov no tus kheej - tiv thaiv txheej, SPA-C steel phaj muab kev ua haujlwm ruaj khov thiab ua haujlwm ntev hauv qhov chaw sab nraum zoov. Nws tuav nws lub zog thiab zoo li yam tsis tas yuav tsum tau ua ntau zaus repainting lossis ua haujlwm hnyav.
Nws muaj zog tiv taus ya raws, ntsev, thiab huab cua hnyav ua rau SPA-C steel phaj zoo tagnrho rau cov ntawv thov xws li txuas hniav, lub tsev façades, cov qauv sab nraum zoov, thiab cov khoom siv kos duab.
Tsis tas li ntawd, SPA-C steel phaj nta zoo weldability thiab zoo formability, ua rau nws yooj yim rau txheej txheem, fabricate, thiab hloov mus rau txawv engineering thiab tsim yuav tsum tau.
Nrog nws cov huab cua zoo dua thiab kev ntseeg tau ntev ntev, SPA-C steel phaj yog cov khoom siv zoo tshaj plaws rau cov haujlwm uas yuav tsum tau muaj zog ntawm cov qauv thiab kev tiv thaiv atmospheric corrosion.
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.
