1. Super Duplex Steel Uns S32750 Coil General Corossion:

• high chromium and molybdenum content of 2507 makes it extremely resistant to uniform corrosion by organic acids like formic and acetic acid.
• provides excellent resistance to inorganic acids, especially those containing chlorides.
•  can be used in dilute hydrochloric acid.
• Pitting need not be a risk in the zone below the borderline in this figure, but crevices must be avoided.

ensitivity. This allows it to maintain its strength properties, stress corrosion cracking resistance and fracture toughness levels.

2.Super Duplex Steel Uns S32750 Coil Intergranural Corossion:

• Low carbon content greatly lowers the risk of carbide precipitation at the grain boundaries during heat treatment.
• Is highly resistant to carbide-related intergranular corrosion.

3. Super Duplex Steel Uns S32750 Coil Stress Corossion Cracking:

• Duplex structure of 2507 provides excellent resistance to chloride stress corrosion cracking (SCC).
• Superior to 2205 in corrosion resistance and strength.
• 2507 is especially useful in offshore oil and gas applications and in wells with either naturally high brine levels or where brine has been injected to enhance recovery.

4. Super Duplex Steel Uns S32750 Coil Pitting Corossion:-

• Different testing methods can be used to establish the pitting resistance of steels in chloride-containing solutions.

5. Super Duplex Steel Uns S32750 Coil Crevice Corossion:-

• Highly resistant to crevice corrosion.
