Incoloy mesh is a woven or welded wire mesh made from Incoloy alloys, a family of nickel-iron-chromium-based superalloys designed for high-temperature and corrosive environments. These alloys offer excellent oxidation resistance, strength, and corrosion resistance, making them ideal for demanding industrial applications.
Key Incoloy Alloys Used for Mesh:
– High resistance to oxidation & carburization.
– Used in furnaces, heat treatment, and petrochemical industries.
– 800H/800HT have improved creep resistance at high temps.
– Enhanced corrosion resistance (acidic & alkaline environments).
– Contains molybdenum & copper for sulfuric/phosphoric acid resistance.
– Common in chemical processing, oil & gas, and marine applications.
3. Incoloy A286:
– Good strength and oxidation resistance, especially at temperatures up to 1300°F (700°C)
-Excellent fabrication characteristics
4. Incoloy 925:
– Age-hardenable alloy with high strength.
– Used in sour gas wells (H₂S resistance) and downhole equipment.
Features of Incoloy Mesh:
✔ High-temperature resistance (up to 2100°F / 1150°C for some grades).
✔ Resists oxidation, carburization, and sulfidation.
✔ Good mechanical strength in corrosive & high-pressure environments.
✔ Performs well in acidic, alkaline, and chloride-rich conditions.
Applications of Incoloy Mesh:
– Chemical Processing: Filters, catalyst support, reactor screens.
– Oil & Gas: Sour gas filtration, wellhead screens.
– Heat Treatment & Furnaces: Mesh belts, radiant tubes.
– Power Generation: Flue gas desulfurization (FGD) systems.
– Marine & Aerospace: Corrosion-resistant shielding & filtration.
Mesh Specifications:
– Weave Types: Crimped weave, Plain weave, twill weave, Dutch weave.
– Wire Diameter: From ultrafine (0.025 mm) to heavy-duty (several mm).
– Mesh Count: Fine (100+ mesh) to coarse (single-digit mesh).
– Forms: Rolls, sheets, custom-cut panels, fabricated parts.
Incoloy Mesh vs. Inconel mesh vs. Hastelloy Mesh:
Alloy Type | Primary Composition | Key Strengths | Best For |
Incoloy | Ni-Fe-Cr (+ Mo, Cu, Ti) | High-temp oxidation resistance, moderate corrosion resistance | Heat exchangers, furnaces, chemical processing |
Inconel | Ni-Cr (+ Mo, Nb) | Extreme temp strength, oxidation resistance | Jet engines, nuclear reactors, high-heat zones |
Hastelloy | Ni-Mo-Cr (+ W, Co) | Best for harsh acids (HCl, H₂SO₄), pitting/crevice corrosion | Chemical reactors, pollution control, aggressive media |
Choosing the Right Incoloy Mesh:
– For high-temperature oxidation resistance → Incoloy 800H/HT
– For acid/chloride resistance → Incoloy 825
– For sour gas (H₂S) environments → Incoloy 925
