Titanium Rod Titanium Round Bar Titanium Welding Rod Commercially
ASTM B348 is a specification that covers Titanium and Titanium
Alloy Bars and Billets for use in various applications, including
medical, aerospace, and industrial sectors. Grade 2 Titanium (also
known as Commercially Pure Titanium or CP Titanium) is one of the
most commonly used grades of titanium, known for its excellent
corrosion resistance, biocompatibility, and lightweight nature.
Below is an overview of ASTM B348 Grade 2 (Gr2) Titanium Rod, Round
Bar, and Welding Rod:
1. Overview of Grade 2 Titanium (CP Ti)
Material Composition:
Grade 2 Titanium is composed of 99% pure titanium, with trace
amounts of other elements like oxygen, nitrogen, and carbon. It has
minimal alloying elements, which gives it its characteristic
properties:
- Aluminum: ~0.2% max
- Iron: ~0.3% max
- Oxygen: ~0.18% max
- Carbon: ~0.08% max
Properties:
- Tensile Strength: 50-70 ksi (345-485 MPa)
- Yield Strength: 40 ksi (275 MPa)
- Elongation: 20-30%
- Density: 4.51 g/cm³
- Corrosion Resistance: Excellent in a variety of environments,
including body fluids and seawater.
- Workability: Very good, especially for applications requiring
welding or machining.
- Biocompatibility: Highly biocompatible, making it suitable for
medical implants.

2. Applications of Grade 2 Titanium
Grade 2 Titanium is widely used in industries that require
corrosion resistance, strength, and light weight. Common
applications include:
- Medical implants: Bone plates, screws, dental implants, and
surgical instruments. Its biocompatibility makes it an excellent
choice for these applications.
- Aerospace components: Used for components exposed to harsh
environments (e.g., aircraft structures, engine parts).
- Marine industry: For seawater-resistant parts like heat exchangers
and valves.
- Chemical processing: Pumps, valves, and tanks where corrosion
resistance is critical.
