Inconel 800H Circles

Inconel 800H Circles

Inconel 800H Circle, also known as UNS N08810, is a nickel, iron and chromium based austenitic alloy derived from Inconel 800 to have better high temperature strength and stability. The alloy is to be used in severe service where high resistance to oxidation, carburization and creep is required. Inconel 800H circles can be offered with 30-35% Ni, 19-23% Cr, and controlled Fe with Ti and Al; these circles are made with high tolerance to suit the industries. 

Chemical Composition of Inconel 800H Circles

The composition of the Inconel 800H Circle is crucial for understanding its properties and performance in various industrial applications.

ElementComposition Range (%)
Nickel (Ni)30.0 - 35.0
Chromium (Cr)19.0 - 23.0
Iron (Fe)Balance
Carbon (C)0.05 - 0.10
Manganese (Mn)1.0 max
Silicon (Si)1.0 max
Sulfur (S)0.015 max
Copper (Cu)0.75 max
Titanium (Ti)0.15 - 0.60

Thus, this table provides valuable insight into the chemical composition of these angles, highlighting their properties and suitability. 

Mechanical Properties of Inconel 800H Circles

The table provides essential information for engineers and manufacturers to assess the integrity and durability of the Inconel 800H Circle in demanding environments.

ElementDensityMelting PointTensile StrengthYield Strength (0.2%Offset)Elongation
800H7.94 g/cm31385 °C (2525 °F)Psi – 75,000 , MPa – 520Psi – 30,000 , MPa – 20530 %

Thus, this valuable data on the Inconel 800H Circle's strength, flexibility, and resilience is crucial for ensuring reliability and longevity.

Advantages of Inconel 800H Circles

These flexible circles offer numerous benefits for various industrial applications.

  • Enhanced High-Temperature Strength: Normal Inconel 800 has improved mechanical properties and high temperature strength compared to Inconel 800H circle. The material can retain its properties up to 1200°C (2192 °F). 
  • Superior Oxidation Resistance: Inconel 800H circle is resistant to oxidation and scaling, preventing the parts from rusting at high temperatures.
  • Excellent Corrosion Resistance: Inconel 800H circle is very immune to carburization, and oxidation, hence making it very useful in very demanding conditions.
  • Good Creep and Stress Rupture Properties: Inconel 800H circle is superior to Inconel 800 circle in terms of creep strength and stress rupture and is used in high stress high temperature applications.
  • Enhanced Fabricability: Machining, welding and forming an Inconel 800H circle is quite possible and the material's properties do not alter during the process.
  • Resistance to Thermal Fatigue: Inconel 800H circle has good thermal fatigue, so the circle does not fail under cyclic thermal conditions.

    Inconel 800H Circle offers several advantages that make it suitable for industrial and commercial applications.

Applications of Inconel 800H Circles

Due to its excellent features, the Inconel 800H Circle is preferred in various industrial applications. Some of the main applications include.
