Excellent resistance to corrosion, especially in seawater & chloride-bearing environments
High strength-to-weight ratio
Outstanding heat transfer efficiency
Available in seamless and welded tube forms
Suitable for heat exchangers, condensers, coolers, and evaporators
Grades designed to meet varied mechanical and corrosion performance
