What’s the key difference between Incoloy 800H and 800HT?
While both alloys share a base composition (Ni-Cr-Fe), 800HT (UNS S38808) has elevated titanium/aluminum (Al+Ti ≥1.2%) for superior creep strength. At 700°C, 800HT delivers 30% higher stress rupture life (85 MPa vs. 65 MPa for 800H at 10,000 hours) per ASTM E139. This makes it ideal for ethylene cracker tubes and high-pressure boilers.
