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.
