Core Material Analysis: Incoloy 800 Superalloy Di Medium ne High-Temperature Application Field no anim a Ɛwɔ Mfaso Titiriw Anan
Sɛ́ classic nickel-dade-chromium alloy, akansi titiriw a ɛwɔ Incoloy 800 mu no da adi wɔ nneɛma atitiriw anan mu:
1.Significant ɛka-adwumayɛ mfaso: Ne composition nhyehyɛe, a dade sɛ matrix ne moderate nickel content, hwɛ hu sɛ high-temperature oxidation resistance ne creep ahoɔden a ɛboro 600℃bere a kura ɛka a ɛba fam sen high-nickel alloys.
