Core characteristics of Inconel600:
High temperature stability: can be used for a long time at 1093°C, and short-term temperature resistance reaches 1177°C.
Corrosion resistance: resistance to chloride ion stress corrosion cracking, acid, alkali and high temperature oxidation.
Processing performance: good hot and cold processing performance, but attention should be paid to work hardening phenomenon.
Inconel600 heat treatment and processing technology:
(1) Heat treatment
Annealing: 871~982°C rapid cooling (water quenching or air cooling) to eliminate stress and optimize ductility.
Stress relief: 593~816°C slow cooling, suitable for welding or cold processing post-processing.
(2) Weldability
Recommended methods: TIG welding, MIG welding, plasma welding, use matching welding materials (such as ERNiCr-3).
Note: Avoid prolonged high temperature dwell time to prevent intergranular corrosion.
(3) Cutting Process
Higher Difficulty: It is recommended to use carbide tools, low speed and high feed rate cutting, and use coolant to reduce thermal effects.
Typical Applications of Inconel600:
Aerospace: engine combustion chambers, turbine seal rings, high-temperature fasteners.
Chemical Equipment: acid treatment containers, heat exchangers, reactor pipes.
Nuclear Industry: nuclear reactor control rod guide tubes, steam generator pipes.
Others: heat treatment furnace components, electronic component sheaths.
