Bright Polish Incoloy 800H Round Bar / Alloy UNS N08810 Round Stainless Steel Bars
Incoloy 800H (UNS N08810) round bars with bright polish finish represent the pinnacle of high-performance alloy engineering, designed for applications demanding both exceptional heat resistance and aesthetic precision. These premium stainless steel bars combine the robust mechanical properties of Alloy 800H with a mirror-like surface finish, making them ideal for industries where functionality meets visual and hygienic requirements. Available in various dimensions, our bright polish UNS N08810 round bars deliver uncompromising performance in extreme environments.
Chemical Composition: The Science Behind Superiority
The exceptional characteristics of Incoloy 800H (UNS N08810) stem from its precisely balanced chemical composition, which ensures stability across a wide temperature range. This alloy is meticulously formulated to resist oxidation, carburization, and creep deformation even under prolonged high-heat exposure.
| Element | Composition Range (%) | Primary Function |
| Nickel (Ni) | 30.0 - 35.0 | Maintains austenitic structure at high temperatures; prevents embrittlement |
| Chromium (Cr) | 19.0 - 23.0 | Forms protective oxide layer; resists oxidation and corrosion |
| Iron (Fe) | Balance | Provides structural base while optimizing cost-efficiency |
| Carbon (C) | 0.05 - 0.10 | Enhances creep strength through carbide formation (defining feature of 800H variant) |
| Aluminum (Al) | 0.15 - 0.60 | Works with titanium to form strengthening precipitates |
| Titanium (Ti) | 0.15 - 0.60 | Stabilizes carbide formation; Al+Ti sum controlled at 0.85-1.20% |
| Manganese (Mn) | ≤1.50 | Aids in deoxidation during manufacturing |
| Silicon (Si) | ≤1.00 | Improves high-temperature oxidation resistance |
| Sulfur (S) | ≤0.015 | Minimized to prevent hot working issues |
| Phosphorus (P) | ≤0.030 | Controlled to avoid brittleness |
Mechanical Properties: Strength That Endures
Bright polish Incoloy 800H round bars maintain exceptional mechanical integrity across a broad temperature spectrum, from cryogenic conditions to extreme heat. The bright polishing process enhances surface hardness without compromising the alloy's core properties.
| Property | Room Temperature | At 815°C (1500°F) |
| Tensile Strength | 450 MPa (min) | 200 MPa (min) |
| Yield Strength (0.2% offset) | 180 MPa (min) | 100 MPa (min) |
| Elongation | 35% (min) | 25% (min) |
| Hardness (Brinell) | 140 - 190 HB | - |
| Modulus of Elasticity | 205 GPa | 165 GPa |
| Density | 7.9 g/cm³ | 7.8 g/cm³ |
| Melting Range | 1300 - 1350°C | - |
Bright Polish Finish: Advantages Beyond Aesthetics
Our UNS N08810 round bars undergo a specialized bright polishing process that creates a smooth, reflective surface with numerous functional benefits:
| Feature | Specification | Advantage |
| Surface Roughness | ≤0.8 μm Ra | Minimizes friction; reduces material buildup |
| Reflectivity | ≥85% light reflection | Enhances heat dissipation in radiant environments |
| Corrosion Resistance | Improved passivation layer | Extends service life in aggressive environments |
| Cleanability | Non-porous surface | Ideal for hygienic applications; easy to sanitize |
| Dimensional Accuracy | ±0.05mm tolerance | Ensures precise fit in critical assemblies |
| Visual Appeal | Mirror-like finish | Suitable for visible components in architectural or equipment applications |
