Inconel Seamless Pipe Specification

Features of Inconel Seamless Pipe

inconel 625 seamless pipe

High-Temperature Chemistry:

Fe/Ni-based alloy strengthened by niobium-tantalum complex (Nb+Ta: 3.15-4.15%). Aluminum/titanium limitation (<0.40%) prevents gamma-prime formation. Chromium (20-23%) develops self-repairing Cr₂O₃ layers at extreme temperatures.

Mechanical Performance Profile:

Creep Rupture: 180 MPa @815°C for 10,000h

Cyclic Oxidation: <0.05 mg/cm² mass loss @980°C (ASTM G54)

Cryogenic Toughness: 120J Charpy impact @-196°C

Fatigue Strength: 550 MPa @10⁷ cycles (R=0.1)

Aerospace Manufacturing:

Cold pilgering achieves wall thickness tolerances of ±5%. Solution annealing at 1150°C under argon cover gas. Continuous eddy current testing detects flaws >0.125mm deep per AMS 2631B.

Demanding Use Cases:

Rocket engine combustion chambers (NASA-STD-5008)

Nuclear fuel cladding in PWR reactors (ASME Sec III)

Deep-sea MPD (managed pressure drilling) systems

Plasma etching chambers in semiconductor fabs

Aerospace Approvals:

AMS 5599 • ESA PSS-01-702 • NADCAP AC7114/1
