Inconel 625 Nickel Alloy Tube 30-426mm OD for Auto Exhaust 0

Polished Nickel Pipe – Inconel 625 Nickel-Based Alloy Tube for Automobile Exhaust

Material Overview

This product is a polished nickel pipe made of Inconel 625, a nickel-based superalloy renowned for its exceptional strength, corrosion resistance, and high-temperature durability, making it ideal for automobile exhaust systems.

1. Composition

Element Content (wt%)
Nickel (Ni) ≥ 58 %
Chromium (Cr) 20–23 %
Molybdenum (Mo) 8–10 %
Iron (Fe) ≤ 5 %
Niobium + Tantalum (Nb + Ta) 3.15–4.15 %
Cobalt (Co) ≤ 1 %
Manganese (Mn) ≤ 0.5 %
Silicon (Si) ≤ 0.5 %
Aluminum (Al) ≤ 0.4 %
Titanium (Ti) ≤ 0.4 %
Carbon (C) ≤ 0.1 %
Phosphorus (P) ≤ 0.015 %
Sulfur (S) ≤ 0.015 %

2. Mechanical Properties


Alloy / Variant Tensile Strength (MPa) Yield Strength (MPa) Elongation (%)
Inconel 625 (general) ≈ 930 MPa ≈ 517 MPa ≈ 42.5 % 
VDM Alloy 625 (annealed) — 
Altemp 625™ ≥ 827 MPa ≥ 414 MPa 45 % 
Inconel 625 (ASM data) 880 MPa — 
Inconel 625LCF™ 769.5 MPa 319 MPa 63 %

3. Key Features

  • Solid solution strengthened, with Mo and Nb imparting high strength—no precipitation hardening required.

  • High fatigue, creep, and thermal fatigue strength over a wide temperature range, from cryogenic up to ~982 °C (1800 °F).

  • Excellent resistance to oxidation, carburization, pitting, crevice corrosion, and nearly immune to chloride stress-corrosion cracking.

  • Readily weldable and fabricable with standard processes; excellent machinability in annealed condition.

4. Applicable Standards

Common specifications and standards for Inconel 625 include:

  • ASTM / ASME: B444/B705 (pipe/tube), B704 (welded tube), B443/B446 (plate/bar)

  • International: EN 2.4856, ISO 6207, AMS 5599/5666/5837/5869, ASME SB443/446

In pipe manufacturing contexts (for polished or bright finishes):

  • ASTM B167 / B444, ASME SB167 / SB444, ASTM B829, AMS 5581

5. Applications in Automobile Exhaust Systems

General Application Domains:

  • Automotive & Aerospace: Exhaust ducts, turbocharger systems, engine components, thrust-reversers

  • Marine / Chemical / Energy: Flare stacks, turbine ducting, chemical handling, nuclear components

Automobile Exhaust-Specific Uses:

  • Exhaust headers/manifolds: Excellent at withstanding cyclic thermal loads and corrosive gas exposure.

  • Turbocharger housings & downstream ducting: Benefit from oxidation resistance and high-temperature strength.

  • Downstream exhaust piping: Polished Inconel 625 resists road corrosion (salt and chemical exposure) and maintains structural integrity under thermal cycling.
