Titanium Grade 11

UNS N52250
W.Nr 3.7225

Description

Titanium Grade 11 has physical and mechanical properties similar to Grade 1. Due to the addition of palladium, it has enhanced corrosion resistance in crevices and reducing acid chloride environments. It has good ductility and cold formability, along with high impact toughness and excellent weldability.

Industries Supplied

Chemical processing, chlorate manufacturing, desalination, and marine applications.
