Incoloy 800H/NS112A/UNS N08810 Bar/Rod/Wire/Forging/Plate/Strip With Superior Mechanical Properties For Heat Exchangers

Incoloy 800H (UNS N08810 / NS112A) is a high-strength, high-temperature nickel-iron-chromium alloy designed for excellent structural stability and oxidation resistance at elevated temperatures (up to 1100°C / 2010°F). It offers enhanced creep and rupture strength due to controlled carbon and aluminum/titanium additions. Available in bar, rod, wire, forging, plate, and strip, it is widely used in furnace components, heat exchangers, petrochemical reformers, and nuclear steam generators. The alloy resists carburization, sulfidation, and chloride stress corrosion cracking, making it ideal for long-term exposure to harsh thermal environments. It is easily fabricated and welded, maintaining mechanical properties after thermal cycling. Incoloy 800H is especially valued in power generation, chemical processing, and heat treatment industries.

Trade Code

Overview of Incoloy 800H

Incoloy 800H is a high-temperature nickel-iron-chromium alloy, developed as a modified version of Incoloy 800, with enhanced creep and stress rupture strength due to controlled carbon and grain size. It's specifically designed for high-temperature structural applications.

Key Features (All Forms)

Superior High-Temperature Strength

• Excellent creep and rupture resistance at temperatures above 600°C (1110°F).
• Suitable for long-term service in high heat.

Good Corrosion and Oxidation Resistance

• Resists oxidation, carburization, and sulfidation in high-temperature environments.
• Good resistance to aqueous corrosion, although it is optimized for hot/dry environments.

Stable Mechanical Properties

• Retains strength, ductility, and stability under thermal cycling.
• Maintains structural integrity under thermal stress and pressure conditions.

Excellent Fabricability

• Can be formed and welded using conventional processes.
• Often used in pressure vessels, and approved under ASME Boiler and Pressure Vessel Code for high-temp use.

Form-Specific Applications

Bar / Rod

• Used for fasteners, shafts, bolts, hangers, and mechanical supports in high-heat zones.
• Strong structural material with reliable creep resistance.

Wire

• Employed in heating elements, support mesh, and weld filler materials.
• Maintains mechanical performance at elevated temperatures.

Forging

• Ideal for custom shapes, flanges, valves, and pressure-containing components in thermal or petrochemical systems.

Plate / Strip

• Applied in furnace components, heat exchanger shells, boiler baffles, and pressure vessels.
• Excellent surface stability and formability.

Common Applications & Industries

• Petrochemical industry (reformer outlet manifolds, piping)
• Power generation (superheaters, reheaters)
• Heat exchangers and boilers
• Industrial furnaces (muffles, trays, supports)
• Nuclear and chemical plants
