- Potential degradation in extremely high-temperature oxidizing environments (>1000°C).
- Higher cobalt alloy price compared to standard alloys, impacting budget considerations.

Corrosion Data for Stellite1 Cobalt Alloy Sheet

Environment	Corrosion Rate (mm/year)
Atmospheric (Urban)	<0.01
Seawater	<0.05
10% Sulfuric Acid	0.1 - 0.3
10% Hydrochloric Acid	0.2 - 0.5

Best Welding and Manufacturing Practices

Stellite1 Cobalt Alloy Sheet supports various welding methods, including:

TIG Welding: Preferred for precision and minimal distortion.
Plasma Arc Welding: Suitable for high-quality welds.
Hardfacing: Common for applying Stellite overlays.

Fabrication involves water jet or laser cutting for precision. Forming is limited due to low ductility, so preheating is recommended to avoid cracking.
