What Is 2205 Coiled Tubing?

Definition and Composition

2205 coiled tubing is a continuous length of duplex stainless steel tubing, typically manufactured to precise specifications and wound onto large reels. The alloy composition of 2205 typically includes approximately 22% chromium, 5% nickel, and 3% molybdenum. This unique blend results in a microstructure that is roughly equal parts austenite and ferrite, providing a balance of strength and corrosion resistance.

Key Chemical Composition:

Element Percentage (%)
Chromium 22.0 – 23.0
Nickel 4.5 – 6.5
Molybdenum 3.0 – 3.5
Carbon ≤ 0.03
Manganese ≤ 2.00
Silicon ≤ 1.00
Nitrogen Enhanced

Physical and Mechanical Properties

- Yield Strength: ≥ 80,000 psi

- Tensile Strength: ≥ 95,000 psi

- Maximum Hardness: 30C Rockwell

- Excellent resistance to pitting, crevice, and stress corrosion cracking
