ASTM B862 / ASME SB862 Gr. 2 / UNS R50400 Titanium Alloy Welded Pipe ERW Pipe
Sep 09, 2025
Products Description
Standards and Chemical Composition
International Standard Equivalents
U.S. ASTM Standard: Grade 2 (ASTM B265/B348)
China Grade: TA2 (GB/T 3620.1)
International ISO Standard: ISO 5832-2 Type 2
Composition Characteristics
Titanium content ≥ 99.2%, with strict impurity control (Fe ≤ 0.30%, O ≤ 0.25%, N ≤ 0.03%). It belongs to the α-type commercially pure titanium category.
Core Physical and Mechanical Properties
Basic Parameters
Density: 4.51 g/cm³
Melting point: 1668°C
Elastic modulus: 103 GPa
Thermal conductivity: 15.2 W/(m·K)
Annealed tensile strength: 345–540 MPa
Elongation: ≥20%
Hardness: ≤195 HB
Environmental Resistance
Resistant to seawater, wet chlorine gas, and nitric acid corrosion, with an annual corrosion rate < 0.01 mm, outperforming 316L stainless steel.
Biocompatibility certified per ISO 5832-2, suitable for medical implants.
Processing and Industrial Applications
Forming Advantages
Excellent cold formability (stamping, tube rolling) and good weldability (TIG/plasma welding).
Hot working temperature recommended: 800–900°C, requiring a neutral atmosphere protection.
Typical Application Fields
Aerospace: Aircraft hydraulic pipelines, engine cooling components (lightweight requirements).
Medical: Non-implant surgical instruments, dental equipment (biocompatibility).
Chemical Industry: Heat exchangers, seawater desalination pipelines (chloride ion corrosion resistance).
