ASTM B862 Gr 2 Titanium Tubing

ASTM B862 Gr 2 defines welded titanium tubing designed for general corrosion resistance and elevated temperature service. It is the go-to grade for industries needing lightweight yet strong tubing for condensers, heat exchangers, chemical process lines, and industrial cooling systems.

What Is ASTM B862 Gr 2?

• ASTM B862 Gr 2 is a commercially pure titanium tubing grade (UNS R50400).

• Delivered as welded tube from flat-rolled titanium, often annealed to improve formability and corrosion resistance.

• Equivalent ASME SB862 Gr 2 is used when projects require ASME Boiler & Pressure Vessel Code compliance.

• Searching for B862 Gr 2 suppliers? We stock and custom fabricate welded titanium tubes for a wide range of industrial applications.

Key Features & Benefits

• Corrosion resistance: Outstanding in seawater, brine, chlorinated, and oxidizing environments.

• Lightweight & strong: ~45% lighter than stainless steel with a 50 ksi (345 MPa) tensile strength minimum.

• Excellent weldability: Suited for on-site fabrication and integration into complex heat exchanger systems.

• High service temperature: Stable up to ~425°C for condensers and process lines.

Available Tube Configurations

• Straight lengths: Standard single or double random.

• U-bend tubes: For shell & tube heat exchangers.

• Spiral/coiled tubing: For compact heat exchange systems.

• Capillary & small OD tubes: For instrumentation and precision systems.

• Ends: Plain (PE), beveled (BE), or custom machined.

Dimensional Range

• Outside Diameter (OD): ~5–1219 mm (0.2″–48″)

• Wall Thickness (WT): 0.5–20 mm (SCH 10–160 equivalents)

• Lengths: Up to 18 m (custom cut available)

• Finish: Pickled, polished, bright annealed

• Tighter tolerances, polished or special coatings can be provided on request.

Standards & Testing

• Manufacturing: Welded (GTAW/TIG), with cold working of welds where specified.

• Heat treatment: Annealed or stress-relieved.

• NDT: Eddy current, ultrasonic, radiography (for welds), hydrostatic.

• Mechanical testing: Tensile (min 50 ksi), yield (min 40 ksi), elongation ≥20%, flattening & flare.

• Certification: Mill Test Certificate (MTC) EN 10204 3.1/3.2, third-party inspection available.

Applications of ASTM B862 Gr 2 Tubing

• Heat exchangers & condensers in chemical, petrochemical, and power plants

• Seawater desalination systems & marine cooling circuits

• Chlorination & acid process equipment

• Pollution control & flue gas scrubbers

• Pharmaceutical & food processing where cleanliness & corrosion resistance matter

• Industrial piping requiring lightweight, long-lasting service
