Titanium Grade 2 is a popular material choice for various industries due to its excellent combination of strength, corrosion resistance, and formability. In this blog, we’ll explore the chemical composition of Titanium Grade 2 and its implications for Titanium Gr.2 Plates, which are widely used in aerospace, marine, and chemical processing applications.
What is Titanium Grade 2?
Titanium Grade 2 is commercially pure titanium that offers good ductility, corrosion resistance, and moderate strength. It’s often used in applications where a balance of these properties is crucial. The material is designated as “Grade 2” based on its purity and composition, according to ASTM standards.
Chemical Composition of Titanium Grade 2
The chemical composition of Titanium Grade 2 is essential for determining its properties and suitability for different applications. Below is a detailed breakdown of its composition.
Chemical Composition of Titanium Grade 2
| Element | Composition (%) |
| Titanium (Ti) | 98.9 – 99.8 |
| Iron (Fe) | ≤ 0.30 |
| Oxygen (O) | ≤ 0.25 |
| Carbon (C) | ≤ 0.08 |
| Nitrogen (N) | ≤ 0.03 |
| Hydrogen (H) | ≤ 0.015 |
Notes:
- Titanium (Ti): The primary element in Titanium Grade 2, ensuring the material’s core properties.
- Iron (Fe): Limited to a maximum of 0.30% to prevent adverse effects on strength and corrosion resistance.
- Oxygen (O): Kept low to maintain ductility and reduce brittleness.
- Carbon (C): Controlled to avoid compromising the material’s mechanical properties.
- Nitrogen (N): Maintained at a low level to prevent unwanted hardening.
- Hydrogen (H): Minimized to avoid significant degradation of mechanical properties.
