Inconel 600 demonstrates outstanding oxidation resistance up to 1093°C (2000°F), making it ideal for continuous use in high-temperature environments. It maintains structural integrity in furnace components, heat-treating fixtures, and incinerators, where other materials may fail due to thermal degradation.
Chloride Environments: Resistant to chloride-ion stress corrosion cracking, a critical advantage in marine and chemical processing applications.
Alkaline & Sulfur Compounds: Performs well in caustic solutions and environments with sulfur compounds, such as oil refining and gas processing.
Neutral & Salt Solutions: Unaffected by most neutral and alkaline salt solutions, making it suitable for food processing and pharmaceutical equipment.
The alloy offers a minimum tensile strength of 517 MPa and elongation of 30%, balancing durability with formability.
It retains mechanical properties across a wide temperature range, from cryogenic to high-heat applications.
Inconel 600 is readily weldable using standard techniques (TIG, MIG, stick welding) without compromising its corrosion resistance. It supports cold forming and machining, allowing complex designs for specialized equipment.
Its non-magnetic nature and resistance to contamination make it suitable for precision instruments and applications requiring material purity, such as electronics and nuclear power.

Inconel 601 offers enhanced high-temperature oxidation resistance compared to 600, thanks to its aluminum content. While 600 excels in general corrosion resistance, 601 is preferred for extreme oxidation environments like furnace linings.
Inconel 600 has poor resistance to strong oxidizing solutions like hot concentrated nitric acid. For such environments, alloys with higher chromium content (e.g., Inconel 625) are more suitable.
Inconel 600 can withstand continuous service up to 1093°C (2000°F), maintaining oxidation resistance and mechanical stability.
No, Inconel 600 is non-magnetic, making it suitable for applications where magnetic interference must be avoided, such as in electronic components.
Inconel 600 resists chloride-ion stress corrosion cracking in seawater, making it suitable for marine hardware, desalination plants, and offshore structures.
Use nickel-based filler metals and control heat input to prevent carbide precipitation. Post-weld annealing may be recommended for critical applications to restore ductility.
Standard pickling or bright annealing is sufficient for most applications. Polishing can be applied for aesthetic or hygienic requirements in food/pharmaceutical industries.
Standard mill test certificates are included, and 3.2 Certification is available upon request to meet specific industry standards.
