Durable Incoloy 800HT High Temperature Alloy Strip for Furnace and Heat Exchanger Systems

1. Product Description‌

• ‌Enhanced Grade‌: Incoloy 800HT (UNS N08811)

• ‌Certifications‌: RoHS 3.0, REACH SVHC compliant

• ‌Optimized Composition‌:
  Ni 30-34%, Cr 19-22%, Nb 0.3-0.7%, Al+Ti ≥0.85%

• ‌Precision Fabrication‌:
  Ultra-thin strips (0.05±0.002 mm) up to 1,200 mm wide.

• ‌Surface Options‌:
  Mill finish or grit-blasted (#180–#320).

‌2. Enhanced Properties‌

• ‌Creep Resistance‌: 1.2×10⁻⁸ s⁻¹ steady-state creep rate at 750°C/100 MPa.

• ‌Fatigue Strength‌: 1.8× improvement in cyclic stress endurance (250 MPa, >10⁷ cycles).

• ‌Carburization Resistance‌: ≤50 µm penetration depth after 1,000 hours in CH4 atmosphere.

• ‌Grain Boundary Engineering (GBE)‌: Increases rupture life by 40% through controlled grain boundary design.

‌3. Advanced Manufacturing‌

• ‌Double Melting‌: Vacuum Induction Melting (VIM) + Electroslag Remelting (ESR) achieves ASTM E45 A-level inclusion control.

• ‌Nano-Coated Rolls‌: Enable submicron-level surface uniformity.

• ‌AI-Driven Annealing‌: Machine learning algorithms predict optimal annealing temperatures, stabilizing grain size at ASTM 6–8.

‌4. Theoretical Basis‌

• ‌Dynamic Strain Aging (DSA)‌: Dislocation density modulation enhances high-temperature strength.

• ‌Hall-Petch Optimization‌: Yield strength increases by 25% at 5 µm grain size.

• ‌Computational Design‌: CALPHAD modeling adjusts Ti/C/N ratios to suppress σ-phase formation.

‌5. Emerging Applications‌

• ‌Renewable Energy‌: Interconnects for solid oxide fuel cells (ASR <10 mΩ·cm²).

• ‌Waste Treatment‌: Catalyst substrates for dioxin decomposition in incinerators.

• ‌Semiconductor Manufacturing‌: Heat treatment fixtures with ≤0.02 mm/m flatness.

• ‌Oil & Gas‌: Flexible risers for sour service (H2S partial pressure resistance up to 5 MPa).
