GR2 High Performance Titanium Straight Tube

Consistent purity: Compliant with ASTM B338 / ASTM B861 / ASME SB-338; typical purity ≥99.2%

Lightweight, strong: Density ~4.51 g/cm³; 40–50% weight reduction vs. stainless steel

Excellent corrosion resistance: Stable in seawater, chlorides, and mild acid/alkali media

High-temperature capability: Reliable strength and toughness up to ~300°C (higher for short durations)

Biocompatible: Nickel-free, non-toxic; suitable for medical and food-contact scenarios

Fully customizable: OD, wall, length, surface finish, and tolerance classes

GR2 (Grade 2) titanium straight tubes combine medium strength, outstanding formability, and superior corrosion resistance, making them ideal for aerospace, chemical processing, marine, automotive, medical, and premium sports equipment. Produced via vacuum melting and precision cold working, both inner and outer surfaces are clean and smooth with stable dimensions. The tubes offer excellent weldability and machinability for projects demanding low weight, reliability, and long service life.
