Titanium Grade 2 Introduction to Characteristics and Execution Standards

Titanium Grade 2 Introduction to Characteristics and Execution Standards

Common Trade Names: Titanium Grade 2; Commercially Pure Titanium Grade 2;

Titanium Grade 2  UNS R50400, Of the four commercially pure (C.P.) titanium grades, Grade 2 is typically used in applications that require superior corrosion resistance in various aggressive media. Corrosion resistance is similar between these four C.P. grades but mechanical properties vary along with varying oxygen and iron contents.

Typical applications for the “C.P.” grades include chemical process, petroleum refining,

biomedical as well as heat exchangers in an array of different applications. Continuous

service temperatures can reach up to 800°F with occasional, intermittent service at 1000°F.

Titanium’s C.P. grades corrosion resistance comes from a strongly adherent, stable,

protective oxide film, which forms in the presence of oxygen. This film makes the commercially pure titanium grades resistant to most oxidizing, neutral and inhibited reducing as well as mildly reducing environments. Strong reducing media may cause heavy corrosion.

Available Product Forms:Pipe, tube, sheet, strip, plate, round bar, flat bar, forging stock, hexagon and wire.
