Stress-Rupture Strength

HAYNES® 242® alloy is an is an age-hardenable material which combines excellent strength and ductility in the aged condition with good fabricability in the annealed condition. It is particularly effective for strength-limited applications up to 1300°F (705°C), where its strength is as much as double that for typical solid-solution strengthened alloys. It may be used at higher temperatures, where its solid-solution strength is still excellent, but oxidation resistance limits such uses to about 1500-1600°F (815-870°C).
