ASTM B338 Gr.2 Seamless Titanium Steel Heat Exchanger Tube, For Corrosion Resistance Environment

ASTM B338 Gr.2 Seamless Titanium Heat Exchanger Tube is a high-performance product designed to meet the demanding requirements of heat transfer applications in industries such as chemical processing, power generation, marine systems, and more. These tubes, made from commercially pure Grade 2 titanium, are widely recognized for their exceptional corrosion resistance, lightweight properties, and superior mechanical performance.

1. Material Overview

• Grade 2 Titanium (Gr.2):
  • Grade 2 titanium is a commercially pure titanium alloy known for its moderate strength, excellent corrosion resistance, and excellent weldability. It is the most commonly used grade of titanium for industrial applications.
  • Chemical Composition (ASTM B338 Specifications):
    • Titanium (Ti): Balance
    • Iron (Fe): ≤ 0.30%
    • Carbon (C): ≤ 0.08%
    • Nitrogen (N): ≤ 0.03%
    • Hydrogen (H): ≤ 0.015%
    • Oxygen (O): ≤ 0.25%
  • This composition ensures the material’s outstanding resistance to corrosion, especially in environments containing chlorides, seawater, and acidic or oxidizing media.

2. Key Features

1. Corrosion Resistance:

   • Exceptional resistance to corrosion in a wide variety of harsh environments, including saltwater, brackish water, and acidic media.
   • High resistance to pitting, crevice corrosion, and stress corrosion cracking.

2. Lightweight:

   • Titanium is approximately 45% lighter than stainless steel, which makes it an ideal material for applications where weight reduction is critical.

3. High-Strength-to-Weight Ratio:

   • Despite being lightweight, Grade 2 titanium offers impressive strength, making it an excellent choice for structural integrity under high-pressure conditions.

4. Thermal Conductivity:

   • Superior heat transfer properties make it ideal for heat exchanger applications.

5. Biocompatibility:

   • Non-toxic and biocompatible, making it suitable for applications in the medical and pharmaceutical industries.

6. Durability and Longevity:

   • Resistant to erosion and corrosion, ensuring a longer service life even in aggressive environments.

3. Applications
