Mechanical Properties

2. Key Adventages

• Excellent Intergranular Corrosion Resistance

Stabilized with Titanium (Ti) to effectively prevent intergranular corrosion in the carbide precipitation sensitization range (450-850°C). Ideal for components that cannot be solution annealed after welding.

• Superior High-Temperature Performance

It maintains good oxidation resistance, creep resistance and long-term strength even at high temperatures, making it a reliable choice for boiler, superheater and heat exchanger tubes.

• Bright Annealed (BA) Surface

Annealed in a controlled atmosphere furnace resulting in a smooth, bright, and scale-free surface. This finish is easy to clean, reduces the risk of product contamination, and enhances corrosion resistance.

• High Dimensional Accuracy and Consistency

Manufactured with advanced welding and cold-reduction processes ensuring tight dimensional tolerances, uniform wall thickness, and excellent concentricity.

• Broad Chemical Resistance

Good resistance to a wide range of organic and inorganic chemicals, as well as oxidizing media.

3. Key Applications

• Shell and Tube Heat Exchangers

• Condensers and Evaporators

• Boiler Tubes

• Food & Beverage Processing Equipment

• Pharmaceutical and Biotech Systems (CIP/SIP)

• Chemical and Petrochemical Process Plants

• Marine and Offshore Systems
