Material properties

UNS J94003 is a high chromium-nickel alloy classified under ASTM A297, known for its exceptional heat resistance and strength at elevated temperatures. This material is designed for severe high-temperature applications where both corrosion resistance and mechanical stability are critical. It is especially suitable for environments up to 1800°F (980°C), where it maintains superior oxidation resistance and durability under continuous exposure to high temperatures and corrosive conditions.

Advantage

1. Excellent high-temperature strength and stability.
2. Superior oxidation resistance in extreme heat.
3. Maintains mechanical properties at high temperatures.
4. Resists corrosion in high-temperature environments.
5. Suitable for complex shapes due to good castability.

Application

UNS J94003 is extensively used in the manufacture of components that require exceptional heat resistance, such as parts for furnaces, heat exchangers, and other high-temperature processing equipment. Its robust properties make it ideal for petrochemical, power generation, and aerospace industries, where materials are exposed to harsh thermal and chemical conditions, demanding reliability and longevity.
