Titanium (Ti) 0.15-0.60
Manganese (Mn) ≤1.5
Silicon (Si) ≤1.0
Physical & Mechanical Properties
Property Value
Density 7.94 g/cm³
Melting Range 1350-1400°C
Modulus of Elasticity 196.5 kN/mm² (20°C)
Tensile Strength ≥500 N/mm²
Yield Strength ≥210 N/mm²
Elongation ≥35%
Brinell Hardness ≤210 HB
Key Performance Advantages
Incoloy 800H maintains stable mechanical properties across 650°C to 1100°C, with strength retention of 40% at 815°C—double that of 304 stainless steel. Its CrO-AlO composite oxide layer blocks carbon penetration, limiting depth to 20μm after 1000 hours at 900°C, compared to 150μm for 304 stainless steel.
Industrial Applications
  • Petrochemical: Crack furnace tubes, reactors, and heat exchangers
  • Power Generation: Superheaters and steam pipes in ultra-supercritical power plants
  • Nuclear Industry: Fuel handling equipment and control systems
  • Aerospace: Engine combustion chambers and turbine components
Incoloy 800H round bar offers excellent processability, compatible with hot and cold working, while meeting global quality standards with ISO, SGS, and BV certifications. For industries operating in extreme thermal and corrosive conditions, it represents a strategic investment that reduces downtime, lowers maintenance costs, and ensures operational safety.
