Project Description
Product Description
Titanium Grade 2 (UNS R50400, DIN 3.7035) is commercially pure titanium offering excellent corrosion resistance and weldability. Containing 98.9% minimum titanium content, this non-alloyed material finds extensive applications in chemical processing, marine engineering, and medical equipment industries. We supply Grade 2 titanium in both seamless and welded tube to ASTM B338, and as seamless pipe to ASTM B861 or welded pipe to ASTM B862 depending on the size and the project specification.
Applications
Grade 2 titanium pipes/tubes are widely used as:
- Heat exchanger tubing in desalination plants
- Hydraulic lines for offshore platforms
- Medical gas delivery systems
- Chemical processing piping systems
- Architectural structural components
Chemical Composition
Typical composition ranges include 98.9-99.7% Titanium base with maximum allowances of 0.25% Iron, 0.1% Carbon, 0.03% Nitrogen, 0.015% Hydrogen, and 0.18-0.28% Oxygen content.
Mechanical Properties
Tube-specific mechanical characteristics:
- Tensile Strength: 345-483 MPa
- Yield Strength: 275-414 MPa
- Elongation: 20-28%
- Hardness: 120-180 HV
Production Sizes
Available in both seamless and welded configurations:
- Outer Diameter: 6mm – 325mm
- Wall Thickness: 0.5mm – 25mm
- Length: Custom cut up to 12 meters

Grade 2 titanium tube data
Grade 2 is the grade to quote when the duty is heat exchanger tubing, chemical process lines, marine and desalination service. The mechanical values above are the ASTM B338 minima, so a mill certificate that meets them can be released against either the tube or the pipe specification depending on the product form ordered.

Titanium is priced per kilogram but sold per metre, and the two do not track each other when the wall changes. Send OD × wall, length and the test standard, and the offer will state both the theoretical weight per metre and the price basis so the two can be compared across suppliers.
