Product : JIS G4902/NCF 800
JIS G4902/NCF 800 Nickel base alloy due to its Ni, Cr content is high, so oxidation at high temperatures and high resistance to carburization, oxidation resistance superior to SUS 310S, even close to NAS 600. High temperature strength and NAS 600 is basically the same. During use will not lead to precipitation of σ phase and embrittlement, is widely used in heat-resistant material.
Generally in the temperature range below 600 ℃. If used at higher temperatures, and creep performance requirements, it is recommended to use NAS 800H/NAS 800T.
