This data is for use as a guide only as other factors beside the corrosive material, influence corrosion.
I - Fully resistant
II - Satisfactorily resistant
III - Fairly resistant
IV - Slightly resistant
V - Not resistant.

*Subject to pitting at liquid line when allowed to dry. We will furnish alloy samples for testing.

Greenville Tube and RathGibson do not assume any liabilities that arise as a result of corrosion.
