ASTM B338 Titanium Grade 9 Ti-3-2.5 alloy Seamless and Welded Tube

GNEE's Grade 9 titanium tubing is a titanium alloy with superior resistance to seawater corrosion and higher mechanical properties than stainless steel. Ti 3-2.5 tubing can be bent at room temperature using standard bending techniques. Its typical bending radius is three times the tube diameter. Furthermore, the thin-walled tubing requires sufficient support of the inner diameter during bending. Due to the alloy's high strength and low modulus, its spring stiffness is approximately twice that of stainless steel.

Characteristics of the Ti-3-2.5 alloy include:

Excellent resistance to seawater corrosion

Highest mechanical strength

Excellent strength-to-weight ratio

Excellent resistance to stress corrosion cracking in chloride and acidic gas environments

Excellent resistance to pitting, crevice corrosion, and erosion corrosion

Good formability and weldability

Extremely low coefficient of thermal expansion

GNEE's proprietary processing technology imparts excellent fatigue properties and also controls crystal texture.
