Production and Processing Technology

At TSM Technology, we employ advanced manufacturing techniques to ensure the highest quality Monel 404 Tube:

Process	Details
Welding	Welds with matching composition filler metals. Suitable methods include gas tungsten arc welding (GTAW) and gas metal arc welding (GMAW).
Machining	Requires sharp tools and proper cooling. Carbide tools are recommended for turning and milling operations.
Polishing	Achieves a good surface finish with mechanical methods like buffing and polishing wheels. Chemical polishing is also effective.
Heat Treatment	Annealing at 870°C (1600°F) followed by water quenching improves ductility and removes residual stresses.
Cold Working	It can be cold worked to various degrees for shaping. Cold working increases strength and hardness.
