Incoloy 800 Wires

Incoloy 800 wires (UNS N08800) are nickel-iron-chromium alloy products prized for their strength and resistance to oxidation/carburization at elevated temperatures up to 1100°C.

These wires boast ultimate tensile strength of ?420 MPa (75 KSI min), yield strength ?207 MPa (30 KSI for gauges ?0.020"), 30% elongation, and Rockwell B84 hardness, with a melting point of 1385°C and low magnetic permeability. Their composition (30-35% Ni, 19-23% Cr, Al/Ti stabilizers) ensures stability in nitriding, sulfidation, and acidic media.

Produced per ASTM B408/ASME SB408 as filler, spring, weaving, or welding wires (e.g., ERNiCr-3) in diameters 0.2–10mm, spools up to 150kg, annealed/bright finishes, and forms like coils or straight lengths. Variants like 800H offer creep resistance.

Ideal for furnace components, heat exchangers, welding consumables, mesh screens, and springs in petrochemicals, power generation, and nitric acid plants
