Incoloy 800 / 800H / 800HT Round Bar Hot Rolled Black Surface Custom Cutting Any Length
Incoloy 800, 800H, and 800HT round bars represent a family of high-performance nickel-iron-chromium alloys engineered for extreme-temperature applications. Our hot-rolled black surface round bars combine robust mechanical properties with customizable sizing, making them the preferred choice for industries requiring reliability in harsh environments. Whether for chemical processing, power generation, or petrochemical equipment, these alloys deliver unmatched stability and corrosion resistance.
Core Alloy Overview: 800 vs. 800H vs. 800HT
While all three alloys share a nickel-chromium-iron base, precise variations in chemical composition distinguish their performance capabilities, particularly in high-temperature scenarios. The controlled addition of carbon, aluminum, and titanium tailors their strength and creep resistance for specific operating conditions.
Chemical Composition Comparison (%)
| Element | Incoloy 800 (UNS N08800) | Incoloy 800H (UNS N08810) | Incoloy 800HT (UNS N08811) |
|---|---|---|---|

Key Mechanical Properties
The hot-rolling process enhances the alloys’ structural integrity, while their chemical makeup ensures performance across temperature ranges. Below are typical mechanical properties for annealed round bars:
| Property | Incoloy 800 | Incoloy 800H | Incoloy 800HT |
|---|---|---|---|
| Tensile Strength (MPa) | 500 – 650 | 520 – 690 | 600 – 800 |
| Yield Strength (MPa) | 200 – 350 | 210 – 400 | 220 – 380 |
| Elongation (%) | Min. 30 | Min. 30 | Min. 30 |
| Hardness (HRC) | ≤ 28 | ≤ 30 | ≤ 30 |
| 1000h Creep Strength at 700°C (MPa) | N/A | 120 | 150 |
Product Specifications: Hot Rolled Black Surface
Our Incoloy 800/800H/800HT round bars feature a hot-rolled black surface—an industrial finish formed during the rolling process that retains the alloy’s natural oxide layer, providing initial corrosion protection. This finish is ideal for applications where a rough surface is acceptable or will be further processed (e.g., machining, welding).
| Specification Item | Details |
|---|---|
| Manufacturing Process | Hot rolling (1100°C – 1200°C) |
| Surface Finish | Hot-rolled black (mill scale, no additional polishing) |
| Diameter Range | 5mm – 500mm |
| Length Options | Standard: up to 12 meters; Custom: any length (precision cutting) |
| Tolerances | Diameter: ±0.5mm (for ≤50mm); ±1% (for >50mm); Length: ±2mm |
| Certifications | ASTM/ASME SB 408, NACE MR0175, EN 10204 3.1B |
| Heat Treatment | Annealed at min. 1149°C for grain refinement (ASTM 5 or coarser) |
Performance Advantages
These alloys excel in environments where standard stainless steels fail, offering four key benefits:
-
High-Temperature Resilience: Incoloy 800 performs reliably up to 815°C, while 800H/HT extend this capability to 1000°C, retaining strength and resisting oxidation and carburization . 800HT’s higher titanium content further boosts creep resistance for long-term high-heat service .
-
Corrosion Resistance: The chromium-nickel matrix provides protection against oxidizing/reducing environments, including nitric acid, steam, and industrial gases—critical for chemical and nuclear applications .
-
Fabrication Versatility: Despite limited cold-working capacity, the alloys offer good weldability with matching filler metals, and their hot-rolled form accepts machining, forging, and heat treatment .
-
Customization Flexibility: Precision cutting to any length eliminates material waste, supporting projects from small-scale prototypes to large industrial installations.
Industry Applications
Each alloy variant targets specific industrial needs based on temperature and stress requirements:
-
Incoloy 800: Ideal for moderate-temperature corrosion resistance in heat exchangers, nuclear steam generator tubing, and furnace muffles . Its balanced composition suits chemical processing equipment handling mixed oxidizing/reducing media.
-
Incoloy 800H: Preferred for high-temperature components like petrochemical process heaters, ethylene furnace quench boilers, and gasification systems . Controlled carbon content enhances strength without sacrificing ductility.
-
Incoloy 800HT: Excels in extreme heat applications such as turbine components, thermal processing equipment, and 700°C+ industrial furnaces. Its superior creep strength ensures longevity in 10,000+ hour service cycles .
