Haynes Superalloy 242
Oxidation & Corrosion Resistant

Haynes 242 (UNS N10242) is an age-hardenable nickel-molybdenum-chromium alloy that combines excellent high-temperature strength with very low thermal expansion. It is widely used in aerospace, chemical, and power generation industries because it provides outstanding dimensional stability, fatigue resistance, and oxidation resistance up to 815 °C (1500 °F), making it ideal for critical operations under extreme conditions.

Haynes 242 offers a unique combination of properties including exceptional strength at elevated temperatures, the lowest thermal expansion among comparable superalloys, high resistance to oxidation, and excellent fatigue and creep performance. It has a tensile strength ranging from 105 to 218 ksi depending on form, with yield strength up to 140 ksi, and maintains structural stability up to 705 °C (1300 °F). Its weldability and formability, even in the age-hardened condition, make it a versatile alloy for demanding applications.

Haynes 242 is widely used in aerospace and gas turbines for seal rings, ducting, fuel nozzles, and containment casings. In chemical and petrochemical industries, it is used for HF and fluorine resistant components, reactors, and extrusion screws. It also finds applications in industrial furnaces for press tooling, heat exchangers, and furnace parts, in nuclear and specialty energy sectors for controlled expansion components, and in power generation for boiler superheaters and gas turbine hardware.
