Corrosion Data for GH5188 Cobalt Alloy Plate

Environment	Corrosion Rate (mm/year)
Atmospheric (Urban)	<0.01
Seawater	0.02-0.05
Dilute Sulfuric Acid	0.05-0.1
Hydrochloric Acid (5%)	0.1-0.2

Best Welding and Manufacturing Practices

The GH5188 Cobalt Alloy Plate supports multiple welding methods, including TIG, MIG, and plasma arc welding. Preheating to 200°C is recommended to prevent cracking. Forming techniques like bending and rolling are effective, but high forces are required due to the alloy’s strength. Machining requires carbide tools for precision.
