347 stainless hlau muab kev tiv thaiv zoo heev rau oxidation thiab scaling ntawm qhov kub thiab txias, piv rau 321 thiab superior rau 304 hauv cyclic cua sov.
Cov niobium ntxiv muaj kev tiv thaiv intergranular corrosion, tshwj xeeb tshaj yog tom qab vuam lossis raug rau 425-850 degree. Txawm li cas los xij, rau kev ua haujlwm siab ntxiv - qhov kub thiab txias (siab dua 600 degree), 347H raug pom zoo vim nws qhov kev txhim kho creep zog los ntawm cov ntsiab lus carbon ntau dua.
