‌Incoloy 800HT High-Temperature Corrosion-Resistant Alloy Bar

Incoloy 800HT Alloy Bar Performance Characteristics and Applications

1. Performance Characteristics

1.1 High-Temperature Stability
Incoloy 800HT can operate stably at temperatures between 700°C and 1100°C for extended periods, maintaining strength and toughness without deformation or embrittlement. Its unique alloy composition and microstructure impart excellent creep resistance, making it suitable for extreme operating conditions with frequent temperature fluctuations.

1.2 Corrosion Resistance
It exhibits strong resistance to corrosive media such as acids, alkalis, and salts, and performs particularly well in chemical and marine environments. The chromium element forms a dense oxide film that effectively prevents oxidation and carburization, extending service life.

1.3 Mechanical Properties
It combines high strength, hardness, and toughness to withstand high loads and impacts. It exhibits excellent processability and is suitable for both hot and cold forming. However, the high work hardening rate requires a soft annealing treatment after cold working.

2. Main Applications

2.1 Chemical and Petroleum Industry
Used in the manufacture of reactors, heat exchangers, pipelines, and oil well pipes, protecting against high temperatures, high pressures, and corrosive media, ensuring safe operation of equipment.

2.2 Power and Energy Sector
Used in high-temperature components such as boiler tubes and superheater tubes to improve power generation efficiency; in nuclear power, used in key reactor components to ensure stability.

2.3 Aerospace and Industrial Equipment
Used in the manufacture of engine components, turbine blades, etc., meeting high-strength requirements; suitable for complex structural components such as heat treatment furnaces and pressure vessels.
