Inconel 718 is a precipitation-hardenable nickel-chromium alloy with high strength and good weldability for aerospace and high-temperature service. Inconel and Incoloy are nickel-chromium superalloys engineered to hold their strength, and resist oxidation and corrosion, at high temperature and in aggressive process media.
Product range
- Seamless Pipes — The go-to choice for high-pressure and high-temperature lines.
- ERW Pipes — Economical welded pipe for utility and process piping.
- Welded / EFW Pipes — Fusion-welded construction for large-diameter runs.
- Tubes — Round, square and rectangular tubes, plus U-bends for heat exchangers.
Why engineers choose it
- High-Temperature Strength — Keeps its mechanical strength at high temperature.
- Oxidation Resistance — Resists oxidation and scaling in hot service.
- Corrosion Resistance — Copes well with many acids and chloride media.
- Thermal Stability — Handles thermal cycling in furnaces and heat-treat equipment.
