TITANIUM GRADE 12













Common Name:Titanium Grade 12
Ti-0.3Mo-0.8Ni

UNS Number:  R53400

General Information:

Titanium Alloy Grade 12 is lightly alloyed near-alpha alloy offering improved strength at elevated temperatures and optimum ASME Code design allowables.  The material is readily weldable, and has superior crevice corrosion resistance.This material is very corrosion resistant in highly oxidizing and mildly reducing environments.  The alloy is available as wire, 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.
