High Temperature Corrosion Resistant Inconel Alloy Inconel 600
Strip For Industrial Aerospace
Description
Inconel 600 strip delivers unmatched resistance to extreme heat (up
to 1150°C), oxidation, and chloride stress corrosion cracking.
Compliant with ASTM B168, EN 10095, and AMS 5540P. Ideal for
chemical processing, nuclear reactors, and aerospace components.
Product Overview
Inconel 600 strip is a nickel-chromium-iron alloy engineered for
exceptional performance in high-temperature and corrosive
environments. Comprising 72% nickel (Ni), 14–17% chromium (Cr), and 6–10% iron (Fe), this alloy forms a protective chromium oxide (Cr₂O₃) layer under
thermal stress, ensuring resistance to oxidation, sulfidation, and
chloride-induced stress corrosion cracking (SCC). Its high nickel
content provides stability in reducing conditions and alkaline
solutions, while chromium enhances resistance to oxidizing media.
With a maximum operating temperature of 1150°C in oxidizing atmospheres and 700°C in reducing environments, Inconel 600 strip outperforms stainless
steel in aggressive settings like chemical reactors, nuclear
cooling systems, and aerospace engine components. The alloy’s
mechanical robustness—550–725 MPa tensile strength and 30–35% elongation—enables seamless fabrication into precision parts for heat
exchangers, furnace fixtures, and marine hardware. Compliant with ASTM B168, EN 10095, and SAE AMS 5540P, it meets stringent global standards for industries in Southeast
Asia’s petrochemical plants, Europe’s aerospace sector, and North
America’s nuclear facilities.

FAQs
Q1: What is the maximum continuous service temperature for Inconel
600 strip?
A: 1150°C in oxidizing atmospheres. For reducing environments (e.g.,
hydrogen-rich), limit to 700°C to avoid embrittlement.
Q2: How does Inconel 600 compare to stainless steel in chloride
environments?
A: Inconel 600 resists chloride SCC and pitting corrosion far
better than 316L or 304 stainless steel, making it ideal for marine
and chemical applications.
Q3: Is welding Inconel 600 strip feasible?
A: Yes. Use TIG or MIG welding with Inconel 82/182 filler wire.
Ensure thorough cleaning to prevent contamination-induced cracking.
