Titanium Grade 3

Special Products

Titanium Grade 3

Titanium Grade 3 is a commercially pure titanium alloy offering a balanced combination of moderate strength, good ductility, excellent corrosion resistance, and weldability. Stronger than Grades 1 and 2, but more formable than Grade 4, Grade 3 is ideal for applications requiring structural integrity in corrosive environments, such as chemical processing, marine, aerospace, and power generation industries.

Key Features
  • Moderate to High Strength: Higher tensile and yield strength than Grades 1 and 2.
  • Corrosion Resistance: Excellent performance in oxidizing and mildly reducing environments.
  • Good Formability: Can be formed and cold-worked with ease compared to higher-strength titanium grades.
  • Excellent Weldability: Compatible with most welding techniques for fabrication.
  • Biocompatibility: Suitable for medical use due to its non-toxic and non-reactive nature.
