Incoloy 800H Solid Round Bar Corrosion-Resistant Alloy Stock with Custom Lengths & Diameters

For industries operating in extreme heat and corrosive environments—from petrochemical processing to nuclear power generation—material reliability directly impacts operational safety and efficiency. Incoloy 800H solid round bars emerge as a premier solution, combining exceptional high-temperature strength, robust corrosion resistance, and versatile customization to meet demanding industrial needs. As an enhanced variant of the Incoloy 800 family, this nickel-iron-chromium alloy is engineered to maintain structural integrity where standard metals fail, making it a staple in critical applications worldwide.

Core Composition: The Foundation of Performance

The superior properties of Incoloy 800H stem from its precisely balanced chemical composition, which prioritizes high-temperature stability and corrosion resistance. Unlike generic alloys, its nickel-chromium-iron matrix is optimized with controlled additions of carbon, titanium, and aluminum to prevent sensitization and enhance creep strength.

This composition creates a face-centered cubic lattice structure that retains ductility and strength across extreme temperature fluctuations, from room temperature to 1100°C .

Mechanical & Corrosion Resistance: Engineered for Extremes

Incoloy 800H round bars excel in environments where both mechanical load and chemical attack are constant threats. Their mechanical properties remain consistent even under prolonged exposure to high heat, setting them apart from conventional stainless steels.

Key Mechanical Properties (Annealed Condition)

Beyond mechanical strength, corrosion resistance is where Incoloy 800H truly shines. Its high chromium content forms a dense, adherent oxide layer that resists oxidation, while nickel mitigates stress corrosion cracking in aqueous environments. This alloy performs exceptionally well in:

• Nitric acid and organic acid solutions

• Steam, air, and carbon dioxide mixtures up to 500°C

• Sulfidizing and  atmospheres in petrochemical furnaces

• High-temperature water in nuclear steam generators

Notably, its low carbon content and optimized Ti:C ratio eliminate sensitization risks, ensuring resistance to intergranular corrosion even after welding or heat exposure .

Product Specifications: Customizable for Every Application

Flexibility is critical for industrial components, and our Incoloy 800H round bars are supplied with extensive customization options to match precise project requirements. All stock adheres to international standards including ASTM B408/ASME SB408, DIN, JIS, and EN to guarantee quality and compatibility.

Each batch undergoes rigorous quality testing, including positive material identification (PMI), mechanical property verification, pitting corrosion testing, and macro/microstructural analysis to ensure compliance with industry standards .

Industry Applications: Where Reliability Matters Most

Incoloy 800H round bars are trusted in sectors where equipment failure could lead to catastrophic consequences. Key applications include:

Petrochemical & Chemical Processing

• Cracker tubes and furnace components for hydrocarbon reforming

• Heat exchanger tubes and reactor internals

• Catalyst support structures in corrosive reaction vessels

Power Generation

• Steam generator tubes in nuclear power plants
