Titanium Grade 12

1. Performance Comparison of Titanium Grade 12

Titanium Grade 12 (Gr12) is a corrosion-resistant titanium alloy that offers enhanced performance compared to commercially pure grades such as Gr1 and Gr2. It contains a small addition of nickel (Ni) and molybdenum (Mo), which significantly improves its resistance to crevice corrosion and provides better stability in high-temperature environments.

Compared with Titanium Grade 2, Gr12 delivers higher strength and superior resistance to reducing acids, such as hydrochloric and sulfuric acid. While it does not reach the extreme strength levels of Grade 5 (Ti-6Al-4V), it provides an excellent balance between corrosion resistance, weldability, and elevated temperature performance.

For applications requiring durability in harsh chemical conditions, Titanium Grade 12 Sheet and Titanium Grade 12 Tube are often the preferred choices. As a professional Titanium Grade 12 Supplier, Gr12 is recommended for critical environments where both corrosion resistance and thermal stability are essential.

2. Chemical Composition Comparison

Titanium Grade 12 is a near-alpha titanium alloy, distinguished by the addition of nickel and molybdenum, which enhance its overall performance.

Typical chemical composition includes:

• Titanium (Ti): Balance

• Nickel (Ni): 0.6% – 0.9%

• Molybdenum (Mo): 0.2% – 0.4%

• Oxygen (O): ≤ 0.25%

• Iron (Fe): ≤ 0.30%

• Nitrogen (N): ≤ 0.03%

• Carbon (C): ≤ 0.08%

• Hydrogen (H): ≤ 0.015%

The addition of molybdenum (Mo) plays a critical role in improving corrosion resistance, especially in reducing environments, while also enhancing high-temperature performance. Nickel further contributes to crevice corrosion resistance.

Compared to pure titanium grades, Gr12 offers significantly improved durability in aggressive chemical conditions, making it ideal for Titanium Grade 12 Tube systems and heat exchangers.

3. Application Fields

With its enhanced corrosion resistance and high-temperature capability, Titanium Grade 12 is widely used in demanding industrial applications.

• Chemical Processing Industry: Ideal for heat exchangers, reactors, and piping systems handling strong acids. Titanium Grade 12 Tube is commonly used in these environments.

• Marine Engineering: Excellent resistance to seawater and crevice corrosion makes it suitable for offshore and desalination equipment.

• Oil & Gas Industry: Used in high-corrosion and moderately high-temperature environments, especially in processing systems.

• Power Generation: Suitable for condensers and heat exchangers where both corrosion resistance and temperature stability are required.

• Industrial Fabrication: Titanium Grade 12 Sheet is widely used in equipment manufacturing requiring both strength and corrosion resistance.
