•  

3. Application

• Oil, Gas & Offshore: Subsea pipelines, process piping, topside tubing and umbilicals for hydrocarbon transmission

• Chemical & Petrochemical: Transport of aggressive media including acids, chlorides and corrosive process fluids

• Seawater & Desalination: Intake and discharge pipelines, RO high‑pressure lines and cooling systems

• Flue Gas Treatment: FGD systems and high‑chloride wastewater treatment

• Pulp & Paper and Marine: Equipment exposed to corrosion and erosion

4. Key Advantages

• Excellent Strength-to-Weight Ratio: High yield strength allows 30–50% thinner wall design versus conventional stainless steel, reducing material cost and simplifying installation

• Premium Corrosion Resistance: Outstanding resistance to pitting, crevice corrosion and stress corrosion cracking, especially in chloride environments

• Good Weldability & Workability: Stable welding performance and adaptability for complex fabrication

• Thermal Expansion Close to Carbon Steel: Reduces thermal stress when connected to carbon steel pipelines, simplifying system design
