751

UNS #N07751

751 is a high-strength, nickel-base high-temperature alloy which responds to age hardening for maximum properties. This alloy is highly resistant to chemical corrosion and oxidation, displays low creep rate under high stresses in the 1200/1500°F (650/820°C) temperature range and possesses good rupture properties to 1600°F (870°C).
