Chemical Properties

The Stellite3 Cobalt Excess Alloy Sheet exhibits excellent resistance to acids, alkalis, and oxidizing environments. It performs well in sulfuric and hydrochloric acid solutions but may require caution in highly concentrated nitric acid. Environmental restrictions include avoiding prolonged exposure to extreme saline conditions, which could accelerate pitting corrosion.

Things to Note (Limitations)

While Stellite3 Cobalt Alloy Sheet excels in many environments, note the following limitations:
- High Temperatures: Prolonged exposure above 1000°C may reduce hardness.
- Brittleness: High carbon content may lead to cracking under extreme mechanical stress.
- Cost: Higher cobalt alloy price compared to stainless steel alternatives.

Corrosion Data for Stellite3 Cobalt Alloy Sheet

Environment	Corrosion Rate (mm/year)
Atmospheric (Urban)	<0.01
Mild Chemical (5% H₂SO₄)	0.02-0.05
Seawater	0.05-0.1

Best Welding and Manufacturing Practices

Stellite3 Cobalt Alloy Sheet supports various welding methods, including:

TIG Welding: Preferred for precision and minimal distortion.
Plasma Arc Welding: Suitable for thicker sheets.
Shielded Metal Arc Welding: Used for field repairs.

Fabrication techniques include cutting (laser or waterjet), forming, and machining. Preheating to 200-300°C is recommended to prevent cracking during forming.
