ISO/TR 15608 Material Group 51.1

Material Group 51.1 ISO/TR 15608: Pure titanium with O2 ≤ 0,20%

Features of Titanium pure Group 51.1 ISO/TR 15608

Commercially Pure Titanium Grade 1 is one of the softest and most ductile grades exhibiting the greatest formability. This unalloyed titanium has excellent corrosion resistance property, excellent weldability and is used in a wide variety of applications. The corrosion resistance of Titanium is due to a stable, protective, and strongly adherent oxide film layer. This film forms instantly when a fresh surface is exposed to air or moisture. This film growth is accelerated under strong oxidizing conditions. The Titanium oxide film is capable of healing itself instantly in the presence of moisture or oxygen. Because of this, Titanium applications are common in the fabrication of process equipment of chemical industries.

Welding of Titanium pure Group 51.1 ISO/TR 15608

Commercially pure titanium and most titanium alloys are readily welded by a number of welding processes being used today. The most common method of joining titanium is the gas Tungstenarc (GTAW) process and secondarily is the gas metal-arc (GMAW) process. The techniques for welding titanium resemble those employed with nickel alloys and stainless steels. To achieve sound welds with titanium, primary emphasis is placed on surface cleanliness and the correct use of inert gas shielding.
An essential requirement for successfully arc welding titanium is proper gas shielding. Care must be taken to ensure that inert atmosphere protection is maintained until the weld metal temperature cools below 426°C (800°F).
