Key Material Properties of Alloy X
Oxidation Resistance: Demonstrates extraordinary resistance to oxidation, carburization, and nitriding atmospheres at elevated operational thresholds up to 1900℉ (1038℃).
Thermal Fatigue Defense: Optimized chemistry reduces the risk of thermal cracking under prolonged, cyclic heating and cooling conditions.
Excellent Fabricability: Unlike many high-performance superalloys, Hastelloy X exhibits excellent forming and welding characteristics, allowing it to be easily cold-worked or hot-formed.
Resistance to localized attack: The balanced molybdenum and chromium content provides stable protection against localized high-temperature stress corrosion.
