🔧 What Are Duplex & Super Duplex Alloys?

• Duplex alloys consist of a nearly equal mix of austenitic and ferritic stainless steel structures.

• Super Duplex alloys are an enhanced version with even greater chromium, molybdenum, and nitrogen content.

These alloys offer superior corrosion resistance, particularly in chloride-rich and aggressive environments.

🔌 Key Benefits of Duplex & Super Duplex Alloys

🌪️ Excellent Corrosion Resistance

• Performs well in marine, chemical, and oil & gas environments.

• Withstands pitting, crevice, and stress corrosion cracking.

⚖️ High Mechanical Strength

• Double the strength of austenitic stainless steels.

• Allows for thinner sections and lightweight designs.

📊 Superior Cost Efficiency

• Lower alloy content than comparable stainless steels.

• Reduces overall lifecycle costs due to durability.

🔄 Outstanding Weldability

• Easily fabricated into complex structures.

• Suitable for pressure vessels and large industrial components.
