| R50350 | |
| General Information | |
| Titanium Grade 11 is the equivilent of Grade 1 but with a palladium addition which imparts a significant improvement in resistance to general and localized crevice corrosion in a wide range of reducing acid environments, including chlorides, and where low pH and high temperatures above 180째 F (83째 C) to 500째 F (260째 C) are prevalent. The alloy is available as castings, wire, bar, plate, sheet, forgings, pipe, tubing and billet. | |
