Titanium Grade 2 pipe is a commercially pure titanium pipe manufactured to ASTM B337 / ASME SB337 specification with a minimum titanium content of 99% and tight controls on iron, oxygen, carbon, nitrogen, and hydrogen. Grade 2 titanium offers an excellent combination of moderate strength, ductility, and outstanding corrosion resistance in oxidizing, mildly reducing, and chloride-containing environments.
Titanium Grade 2 pipes are used in chemical processing, desalination plants, offshore oil platforms, pulp and paper mills, marine environments, medical equipment manufacturing, and aerospace applications where lightweight construction combined with superior corrosion resistance to seawater, chlorides, and acids is required.
Spark Steel supplies Titanium Grade 2 seamless and welded pipes conforming to ASTM B337 / ASME SB337 (UNS R50400) in sizes from ½" to 6" NPS. Available in annealed condition with tensile strength minimum 345 MPa and yield strength minimum 275 MPa. Documentation includes EN 10204 3.1 mill certificates, chemical analysis, and mechanical test reports. Welded pipes supplied per ASTM B338.
