Hastelloy B yog lub ntsej muag-centered cubic lattice qauv.
Los ntawm kev tswj cov ntsiab lus ntawm Fe thiab Cr ntawm tus nqi me me, lub brittleness ntawm kev ua yog txo thiab nag lossis daus ntawm N4Mo theem ntawm 700 ℃ thiab 870 ℃ yog tiv thaiv.in txo qhov nruab nrab nrog corrosion kuj zoo heev, xws li ntau yam kub. thiab concentration ntawm hydrochloric acid.Nyob rau hauv nruab nrab ntawm cov concentration ntawm sulfuric acid tov (los yog muaj ib tug npaum li cas ntawm chloride ions) kuj muaj corrosion kuj zoo heev.Tib lub sijhawm tuaj yeem siv rau acetic acid thiab phosphoric acid ib puag ncig.Alloy cov ntaub ntawv tsim nyog tsuas yog nyob rau hauv metallurgical qauv thiab ntshiab siv lead ua qauv thiaj li yuav muaj qhov zoo tshaj plaws corrosion kuj.

•Zoo heev corrosion kuj rau reductive ib puag ncig.
•Kev tiv thaiv zoo heev rau sulfuric acid (tshwj tsis yog cov concentrated) thiab lwm yam tsis-oxidizing acids.
•Kev tiv thaiv zoo rau kev ntxhov siab corrosion tawg (SCC) tshwm sim los ntawm chlorides.
•Zoo heev tiv thaiv corrosion los ntawm cov organic acids.
•Zoo corrosion kuj txawm rau vuam kub cuam tshuam cheeb tsam vim tsis tshua muaj concentration ntawm carbon thiab silicon.
Dav siv nyob rau hauv cov tshuaj, petrochemical, kev tsim hluav taws xob thiab kev tswj cov pa phem cuam tshuam txog kev ua haujlwm thiab
cov khoom siv, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem cuam tshuam nrog ntau cov kua qaub (sulfuric acid, hydrochloric acid,
phosphoric acid, acetic acid thiab lwm yam.
