TITANIUM GRADE 7













Common Name:CP Grade 7  Ti-0.15PD
Titanium Grade 7

UNS Number:                        R52400

General Information

Titanium Alloy Grade 7 with 0.1% palladium is similar to Grade 2, but with improved 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 180ºF (83ºC) to 500ºF (260ºC) are prevalent. The alloy is available as castings, wire, welded tube, pipe, plate, sheet, strip, forgings, bar, and billet.

Forms

Seamless Pipe, Welded Pipe, Seamless Tube, Welded Tube,EFW Pipes, Round Bars, Wires,Sheet, Plate, Forgings, Pipe Fittings and Flanges, Fastners.
