HAYNES® 242® alloy has excellent retained ductility and impact strength after long-term thermal exposure at temperature. Combined with its high strength and low thermal expansion characteristics, this makes for very good containment properties in gas turbine static structures. The graphs below show the retained room-temperature tensile elongation and impact strength for 242® alloy versus other relevent materials after a 4000 hour exposure at 1200°F (650°C).
