FAQ for Buyers
Q: Is UNS N08810 suitable above 1100 °F?
A: Yes. ASTM B407 notes it is normally employed above 1100°F (593°C) where creep and rupture resistance are required.
Q: Why is grain size specified?
A: The alloy is annealed to develop controlled grain size for optimum properties in this temperature range. ASTM B407 requires average grain size ASTM No. 5 or coarser for annealed UNS N08810.
Q: What tests are routine?
A: Hydrostatic or nondestructive electric test on each tube; chemical, mechanical, and grain size tests per lot.
