Incoloy 800 Strips (UNS N08800) are wrought, nickel-iron-chromium alloys designed to withstand continuous exposures up to 816 °C (1500 °F) while resisting oxidation, carburization, and chloride stress-corrosion cracking. The alloy’s chemistry—30.0–35.0 % Ni, 19.0–23.0 % Cr, and ≥ 39.5 % Fe—ensures an austenitic microstructure that remains stable without precipitation hardening. In the annealed strip condition, tensile strengths range from 400 to 600 MPa, yield strengths from 150 to 450 MPa, and elongation exceeds 30 %, delivering a unique balance of strength and ductility for stamping, slitting, and fine blanking . High chromium and aluminum contents form a protective chromia scale at temperature, while silicon and manganese enhance resistance to sulphidation and carburization in gas-turbine and furnace environments. Excellent weldability (TIG/GTAW, EB) and consistent mechanical properties post-weld enable fabrication of diaphragms, bellows, springs, and heat-exchanger fins without embrittlement . Strips are supplied in thicknesses from 0.1 mm to 5 mm and widths up to 300 mm, with mill-annealed or cold-worked finishes per ASTM B407/ASME SB-407, AMS 5542, and ISO 15156-3/NACE MR0175-3.

ASTM B407 / ASME SB-407 – Nickel-iron-chromium strip, sheet & coil
AMS 5542 – Special-quality UNS N08800 strip form
ISO 15156-3 / NACE MR0175-3 – Sour-service compatibility
UNS N08800 / W. Nr. 1.4876 – Alloy designation
Incoloy 800 Strips are widely used for:
Aerospace & Power Generation: Turbine blade shims, combustion-chamber liners, heat-exchanger fins
Chemical & Petrochemical: Reactor internals, heat-exchanger baffles, caustic vapor lines
Furnace Equipment: Radiant tubes, retort baskets, thermocouple protection
Marine & Desalination: Seawater condenser strips, pump impeller liners
Electronics: Heat sinks, electrical contacts, semiconductor-processing trays
Q1: Why choose Incoloy 800 Strips for high-temperature service?
A1: Solid-solution strengthening without precipitation aging
provides stable mechanical properties and oxidation resistance up
to 816 °C, plus resistance to chloride stress-corrosion cracking.
Q2: Are Incoloy 800 Strips weldable and formable?
A2: Yes—TIG/GTAW and electron-beam welding yield sound joints;
excellent ductility (≥ 30 % elongation) supports stamping,
slitting, and fine-blanking with minimal springback.
Q3: What strip dimensions and finishes are available?
A3: Thicknesses from 0.1 mm to 5 mm, widths up to 300 mm; supplied
mill-annealed or cold-worked per ASTM B407/ASME SB-407 and AMS
5542.
