What Are Duplex 2205 Pipe Fittings?

Duplex 2205 pipe fittings are piping components manufactured from Duplex Stainless Steel 2205, a nitrogen-enhanced stainless steel containing approximately equal proportions of austenitic and ferritic microstructures. This unique composition provides a combination of high strength and excellent corrosion resistance that surpasses many conventional stainless steel grades.

These fittings are commonly used to connect, redirect, reduce, or terminate piping systems in industrial applications where reliability and durability are critical.

Key Characteristics of Duplex 2205 Pipe Fittings

• High tensile and yield strength
• Superior corrosion resistance
• Excellent resistance to chloride-induced stress corrosion cracking
• Outstanding fatigue strength
• Long service life
• Low maintenance requirements
• Excellent weldability

Due to these advantages, Duplex 2205 pipe fittings are widely used throughout Pennsylvania’s industrial sectors.

Chemical Composition of Duplex 2205 Pipe Fittings
