Inconel 600 Round Bar: Bright Bar & Forged Black Bar Selection Reference

14:40:03 06/05/2026

(Available Inconel 600 solid bar in multiple diameters, from small bright bar to large forging bar, free sample for buyer evaluation.)

Inconel 600 (UNS N06600 / W.Nr. 2.4816) is a nickel-chromium-iron, solid-solution strengthened alloy widely used in heat treatment, chemical processing, nuclear power, and high-temperature furnace applications. It is not a precipitation-hardening alloy like Inconel 718, but it provides excellent resistance to chloride stress corrosion cracking, good oxidation resistance at elevated temperatures, and reliable mechanical properties across a broad temperature range. Shanghai COCESS Special Alloys Co., Ltd​ supplies Inconel 600 round bars, bright bars, and forged black bars with full EN 10204 3.1 documentation, custom cutting services, and global export support.

Chemical Composition & Basic Data (ASTM B166 / ASME SB166)

Element

Content (wt%)

Role

Nickel (Ni)

≥ 72.0

Base matrix; provides stability in reducing environments and chloride SCC resistance

Chromium (Cr)

14.0 – 17.0

Improves oxidation resistance and moderate corrosion resistance

Iron (Fe)

6.0 – 10.0

Strengthens the alloy and stabilizes the austenitic structure

Carbon (C)

≤ 0.15

Allows limited carbide formation; higher carbon variants available for specific creep needs

Manganese (Mn)

≤ 1.0

Deoxidizer; improves hot workability

Silicon (Si)

≤ 0.50

Deoxidizer; contributes to surface stability

Sulfur (S)

≤ 0.015

Controlled to avoid hot shortness and welding issues

Copper (Cu)

≤ 0.50

Residual element

Key Characteristics & Applications

  • Chloride Stress Corrosion Cracking Resistance:​ Superior to 300-series stainless steels in chloride-containing aqueous environments.

  • High-Temperature Oxidation Resistance:​ Performs well in air up to approximately 1093 °C (2000 °F), forming a protective oxide scale.

  • Caustic Corrosion Resistance:​ Excellent resistance to sodium hydroxide (NaOH) and potassium hydroxide (KOH) solutions, especially at elevated temperatures.

  • Weldability and Formability:​ Can be welded using common techniques (TIG, MIG, SMAW) with matching or overalloyed fillers such as ERNiCr-3. Good cold-forming characteristics in the annealed condition.

Typical Applications:

  • Heat treatment furnaces: radiant tubes, muffles, retorts, annealing baskets, and fixtures

  • Chemical processing: nitric acid concentrators, reactors, and heat exchangers

  • Nuclear power: steam generator tubing and related components

  • Aerospace and thermal processing: combustion chambers, ducting, and high-temperature fasteners
