Product element content and effect on product performance:
Titanium (Ti): The primary element in ASTM B337 Gr2 titanium welded pipe, it provides excellent corrosion resistance and high strength to weight ratio. Titanium increases the durability and resistance of the pipe to corrosive environments, making it ideal for exhaust applications.
Iron (Fe): Trace amounts of iron help to improve the mechanical properties of the pipe. However, excessive iron content can reduce corrosion resistance. gr2 grade titanium limits the iron content to 0.30%.
Oxygen (O): Oxygen content is controlled to improve the mechanical properties and weldability of the pipe, Gr2 grade titanium allows for oxygen content of up to 0.25%. Higher oxygen levels can affect ductility, form brittle compounds and reduce weldability.
Carbon (C): Gr2 titanium welded tubes should contain no more than 0.08% carbon. Controlling the carbon content ensures good weldability and prevents the formation of brittle titanium carbide, which can reduce the performance of the pipe.
Nitrogen (N): The nitrogen content of Gr2 grade titanium should not exceed 0.03%. Higher levels of nitrogen can have a detrimental effect on the ductility and corrosion resistance of the pipe.
Hydrogen (H): The presence of hydrogen can make titanium alloys brittle. gr2 titanium grades limit the hydrogen content to ensure the mechanical integrity of the pipe and to resist hydrogen related problems.
