Incoloy 803 Rods: Superior High-Temperature Performance for Demanding Applications

Incoloy 803 rods are advanced iron-nickel-chromium alloys engineered for superior performance in high-temperature and corrosive environments. With elevated nickel and chromium content, these rods offer exceptional resistance to oxidation, sulfidation, and carburization, making them ideal for demanding applications in petrochemical, chemical, and thermal processing industries.​

Chemical Composition

Incoloy 803 rods are composed of the following elements:​

Element Percentage (%)
Nickel (Ni) 32.0 – 37.0
Chromium (Cr) 25.0 – 29.0
Iron (Fe) Balance*
Carbon (C) 0.06 – 0.10
Aluminum (Al) 0.15 – 0.60
Titanium (Ti) 0.15 – 0.60
Copper (Cu) ≤0.75
Sulfur (S) ≤0.015
Manganese (Mn) ≤1.5
Silicon (Si) ≤1.0

Balance refers to the remaining composition, primarily iron.

Mechanical Properties

The mechanical properties of Incoloy 803 rods are as follows:​

Property Value (Metric) Value (Imperial)
Tensile Strength 586 – 627 MPa 85.0 – 91.0 ksi
Yield Strength 275 – 296 MPa 40.0 – 43.0 ksi
Elongation at Break 45% – 50% 45% – 50%

Physical Properties

Key physical properties include:​

  • Density: 7.86 g/cm³ (0.284 lb/in³)​

  • Melting Range: 1365°C – 1400°C (2490°F – 2555°F)​

  • Young’s Modulus (at 20°C): 195 GPa (28,300 ksi)​

  • Shear Modulus (at 20°C): 73.8 GPa (10,700 ksi)​

  • Poisson’s Ratio (at 20°C): 0.32​

Applications
