Nickel alloy

INCOLOY 800 / 840

Typical applications:

• Tubular heating elements (electric heaters)

• Furnace heating elements

• Cartridge heaters

• Air heaters / duct heaters

Role of the material:

• Used as sheath tubes (outer protective tube of heating elements)

Why INCOLOY 800 / 840:

• Excellent oxidation resistance at high temperatures

• Good creep strength

• Stable in long-term heating cycles

👉 Especially suitable for dry heating / high-temperature air environments

INCOLOY 825

Typical applications:

• Immersion heaters for acidic solutions

• Chemical tanks (pickling, electroplating)

• Seawater or brine heating

Role of the material:

• Sheath tubes directly exposed to corrosive liquids

Why INCOLOY 825:

• Excellent resistance to acids (H₂SO₄, H₃PO₄, etc.)

• Strong resistance to chloride stress corrosion cracking

• Suitable for wet & aggressive environments

👉 Best choice for “corrosion + heating” combined conditions
