UNS N08810 Round Bars ASTM EN DIN GB Standard Incoloy 800H Heat Resistant Stainless Steel

UNS N08810 round bars, widely recognized by the trade name Incoloy 800H, represent a premium grade of nickel-iron-chromium heat-resistant stainless steel engineered for extreme high-temperature applications. This alloy stands out for its balanced combination of high-temperature strength, oxidation resistance, and structural stability, making it a preferred choice across industries that operate under harsh thermal and corrosive conditions. Compliant with global standards including ASTM, EN, DIN, and GB, these round bars deliver consistent performance and reliability for critical engineering projects.

Core Properties: The Foundation of Performance

The exceptional performance of UNS N08810 round bars stems from their precisely controlled chemical composition and resulting material characteristics. Unlike standard stainless steels, Incoloy 800H features a higher carbon content (0.05-0.10%), which enhances its high-temperature strength without compromising ductility . The alloy’s nickel content (30-35%) provides excellent resistance to chloride stress corrosion cracking, while the chromium component (19-23%) forms a protective oxide layer that prevents oxidation even at elevated temperatures up to 1100°C .
 
Key mechanical properties further solidify its suitability for demanding environments. At room temperature, UNS N08810 round bars achieve a tensile strength of 75 ksi (517 MPa) and a yield strength of 30 ksi (207 MPa), with an elongation rate of 30% that facilitates fabrication . Under heat treatment (typically normalizing and annealing), these round bars maintain structural integrity even after prolonged exposure to cyclic temperature fluctuations, avoiding the brittleness that plagues lesser alloys.
 
Thermal properties are another highlight: the alloy exhibits a melting range of 1370-1400°C and a density of 7.7-8.03 × 1000 kg/m³, with thermal conductivity reaching 42.7 W/m-K at 100°C . This thermal stability ensures minimal expansion and contraction, reducing stress on components in high-heat applications.

Global Standards Compliance: Ensuring Quality Across Markets

UNS N08810 round bars adhere to stringent international standards, ensuring compatibility with project specifications worldwide. The table below outlines key corresponding standards across major regions:
 
Standard System Relevant Specifications Key Requirements
ASTM/ASME SB-408, SB-409 Chemical composition limits, tensile strength, dimensional tolerance for hot-rolled and cold-finished bars
EN 1.4958 (W. Nr.) Conforms to EN 10088-1 for heat-resistant alloys, includes testing for oxidation resistance
DIN DIN 17458 Specifies heat treatment procedures, mechanical property testing at ambient and elevated temperatures
GB GB/T 14992 Aligns with national standards for nickel-based alloys, covering fabrication and inspection protocols
 
This multi-standard compliance eliminates barriers for global supply chains, allowing manufacturers to source consistent material for projects in North America, Europe, and Asia.

Dimensional Range & Customization

 
UNS N08810 round bars are available in a comprehensive range of dimensions to accommodate diverse application needs. Standard diameters span from 1mm to 2000mm, with lengths up to 9.8 meters as standard—though custom lengths can be produced to meet specific project requirements . Surface finishes include hot-rolled (black) for general industrial use and cold-drawn (bright) for applications requiring tight dimensional accuracy, such as precision machinery components.
 
Additional customization options include heat treatment services (normalizing, annealing, tempering) and machining processes (turning, milling, grinding) to deliver ready-to-install components. This flexibility reduces lead times for manufacturers and ensures seamless integration into production workflows.

Application Fields: Where Performance Matters Most

The unique combination of heat resistance and corrosion resistance makes UNS N08810 round bars indispensable in industries operating at the edge of material performance:
  • Petrochemical & Chemical Processing: Used for high-temperature furnace tubes, reactor vessels, and heat exchangers. The alloy’s resistance to sulfur-containing gases and corrosive media ensures long service life in cracking units and catalytic reactors .
  • Nuclear Energy: Employed in steam generator tubing and core support structures, where radiation resistance and thermal stability are critical for safety and reliability.
  • Aerospace: Fabricated into turbine components and exhaust systems for aircraft engines, withstanding extreme temperatures during flight operations.
  • Metallurgical Equipment: Used in furnace rails, roller bars, and annealing fixtures that operate continuously at 500-1100°C .
In each application, UNS N08810 round bars outperform conventional stainless steels by maintaining structural integrity and reducing maintenance costs associated with premature material failure.

Fabrication & Maintenance Guidelines

 
While UNS N08810 offers excellent workability, proper fabrication techniques are essential to preserve its properties. The alloy can be welded using standard processes such as TIG and MIG welding, though preheating (150-200°C) and post-weld annealing are recommended to prevent intergranular corrosion . Machining should be performed with carbide tools at moderate speeds, as the alloy’s toughness can cause tool wear at excessive cutting rates.
 
Maintenance requirements are minimal due to the alloy’s inherent corrosion resistance. Routine inspections for scale buildup (common in high-heat environments) and periodic cleaning with mild detergents are sufficient to maintain performance. Unlike carbon steels, UNS N08810 does not require regular painting or coating, reducing long-term operational costs.

Why Choose UNS N08810 Round Bars?

For engineers and procurement professionals, UNS N08810 round bars offer a compelling value proposition:
  • Long-Term Durability: Resists oxidation and corrosion for extended service life in harsh environments.
  • Global Compatibility: Complies with major international standards, simplifying specification and quality control.
  • Versatile Performance: Performs reliably across a wide temperature range (0-1100°C) .
  • Cost Efficiency: Reduces downtime and replacement costs compared to lower-grade heat-resistant materials.
Whether for a chemical plant expansion, nuclear power project, or aerospace component manufacturing, UNS N08810 round bars deliver the performance and reliability required to meet the most challenging engineering demands.
