Hastelloy C-276 muaj cov khoom tseem ceeb hauv qab no: zoo heev corrosion kuj nyob rau hauv ntau yam corrosive media, xws li sulfides thiab chloride ions; thiab zoo heev tiv taus pitting corrosion, crevice corrosion, thiab kev nyuaj siab corrosion cracking.
Alloy C276 yog dab tsi?
Hastelloy C-276 (UNS N10276) yog thawj forged npib tsib xee-chromium-molybdenum alloy. Nws tsis tshua muaj carbon thiab silicon cov ntsiab lus zoo txo cov kev sib tw vuam. Yog li ntawd, nws yog dav siv nyob rau hauv cov tshuaj thiab lwm yam industries thiab boasts ib tug 50-xyoo taug qab cov ntaub ntawv ntawm kev ua tau zoo heev nyob rau hauv ntau corrosive tshuaj ib puag ncig.
Cov yam ntxwv tseem ceeb ntawm Alloy C276:
Kev ua haujlwm zoo heev rau muaj zog oxidizing thiab txo cov neeg ua haujlwm
Kev ua tau zoo heev hauv cov tshuaj chloride- muaj ib puag ncig
Zoo heev tiv taus pitting, crevice corrosion, thiab kev nyuaj siab corrosion cracking
Weldable yam tsis muaj kev tshaj tawm -weld cua sov kho
Haum rau kev siv tshuaj lom neeg hnyav
Alloy 400 yog dab tsi?
Alloy 400, tseem hu ua Monel 400, yog npib tsib xee - tooj liab alloy muaj npe nrov rau nws zoo heev tiv thaiv dej hiav txwv thiab hydrofluoric acid corrosion. Nws yog ib qho ntawm cov nickel alloys tsim ntxov tshaj plaws thiab tseem siv dav hauv kev lag luam marine thiab tshuaj lom neeg.
Cov khoom tseem ceeb ntawm Alloy 400:
Resistant rau dej hiav txwv, dej ntsev, thiab hydrofluoric acid corrosion
Cov khoom siv kho tshuab zoo heev ntawm sub- xoom kub
Zoo thermal conductivity
Zoo heev alkali tsis kam
