Descriptions of Titanium Gr7 Seamless Tube (ASTM B861)
Titanium Grade 7 seamless tube (ASTM B861) is a corrosion-resistant titanium–palladium alloy known for its exceptional performance in highly oxidising or mildly reducing environments. Grade 7 is essentially commercially pure titanium (similar to Gr2) with 0.12–0.25% palladium added, which significantly enhances resistance to crevice corrosion, pitting, and stress corrosion cracking.
Titanium Gr7 seamless tubes provide an excellent combination of corrosion resistance, strength, fabricability, and weldability, making them suitable for demanding chemical, marine, and industrial applications.
Excellent resistance to oxidising and reducing acids
Outstanding performance in chloride-containing environments
High resistance to crevice and pitting corrosion
Fully weldable and easy to fabricate
Suitable for high-purity chemical and pharmaceutical equipment
Titanium Grade 7 exhibits exceptional corrosion resistance in a wide range of environments:
Excellent resistance in neutral solutions, oxidising acids, and oxidising salts.
Highly resistant to wet chlorine gas, chlorite, hypochlorite, and chloride solutions.
Titanium Gr7 can be used in some dilute reducing acids, including:
Nitric acid with various concentrations
Mild sulfuric acid conditions
Highly resistant to saturated solutions of Ba(OH)₂, Ca(OH)₂, and Mg(OH)₂ at room temperature.
Not recommended for boiling sodium hydroxide due to potential corrosion.
Completely resistant to corrosion in seawater.
Performs well in marine splash zones and subsea environments.
Excellent resistance to most organic acids
Exception: Not suitable for formic acid or oxalic acid.
Tensile Strength (min): 348 MPa
Yield Strength (min): 275 MPa (max: 450 MPa)
Elongation (min): 20%
These properties provide a balanced combination of ductility and strength, similar to commercially pure titanium Grade 2 but with superior corrosion performance.
