Titanium Grade 2

1. Performance Comparison of Titanium Grade 2

Titanium Grade 2 (Gr2) is the most widely used commercially pure titanium grade, offering an excellent balance of strength, ductility, and corrosion resistance. Compared with Grade 1, it provides higher mechanical strength while still maintaining good formability, making it ideal for a broad range of industrial applications.

When compared to higher grades such as Gr3 and Gr4, Titanium Grade 2 offers moderate strength with superior workability, which makes it easier to fabricate into products like Titanium Grade 2 Sheet and Titanium Grade 2 Tube. Although it does not match the high strength of alloyed titanium such as Grade 5 (Ti-6Al-4V), its corrosion resistance in oxidizing and mildly reducing environments is outstanding.

As an experienced Titanium Grade 2 Supplier, Gr2 is often recommended as the “go-to” material for customers seeking a cost-effective and versatile titanium solution.

2. Chemical Composition Comparison

Titanium Grade 2 is a commercially pure titanium with a minimum titanium content of approximately 99%, containing slightly higher levels of interstitial elements than Grade 1, which enhances its strength.

Typical chemical composition includes:

• Oxygen (O): ≤ 0.25%

• Iron (Fe): ≤ 0.30%

• Nitrogen (N): ≤ 0.03%

• Carbon (C): ≤ 0.08%

• Hydrogen (H): ≤ 0.015%

Compared to Grade 1, the higher oxygen and iron content in Titanium Grade 2 results in improved strength while maintaining good ductility. Compared to Grades 3 and 4, it offers a better balance between mechanical performance and formability.

Unlike alloyed titanium grades, Gr2 does not contain aluminum or vanadium, ensuring excellent corrosion resistance. This makes it highly suitable for Titanium Grade 2 Tube applications in aggressive chemical and marine environments.

3. Application Fields

Due to its balanced properties, Titanium Grade 2 is widely used across multiple industries and is considered the most versatile titanium grade.

• Chemical Processing Industry: Commonly used for heat exchangers, reactors, and piping systems handling corrosive media. Titanium Grade 2 Tube is especially preferred in these applications.

• Marine Engineering: Excellent resistance to seawater corrosion makes it ideal for desalination systems and offshore structures.

• Oil & Gas / Energy: Used in condensers, heat exchangers, and pressure vessels due to its durability and long service life.

• Medical Industry: Suitable for certain medical devices thanks to its biocompatibility.

• Industrial Fabrication: Titanium Grade 2 Sheet is widely used for fabrication, forming, and welding applications.
