UNS N08810 Heat Resistant Stainless Steel Bar Alloy 800H Diameter 10 - 350mm Hot Rolled & Forged Bars
As a premium austenitic nickel-iron-chromium alloy bar, UNS N08810 (commercially known as Alloy 800H) stands out as the "backbone" of high-temperature industrial applications. Engineered to thrive in environments where ordinary steel succumbs to softening, corrosion, and structural failure, our hot-rolled and forged UNS N08810 round bars—available in diameters from 10mm to 350mm—deliver unmatched stability and durability for critical industrial components.
Core Chemical Composition: The Foundation of High-Temperature Performance
The exceptional properties of UNS N08810 originate from its precisely controlled chemical formulation, which adheres to international standards such as ASTM B408 and ASME SB408. Every batch undergoes rigorous testing to ensure component ratios meet strict tolerances, directly contributing to its heat resistance and structural integrity.

|
Carbon (C) |
0.05 - 0.10 |
Enhances creep and rupture strength via carbide formation (critical 区别 from standard Alloy 800) |
|
Aluminum (Al) |
0.15 - 0.60 |
Forms γ' strengthening phase with titanium; boosts high-temperature hardness |
|
Titanium (Ti) |
0.15 - 0.60 |
Works with Al to reinforce microstructure; Al+Ti sum controlled at 0.85-1.20% |
|
Manganese (Mn) |
≤1.50 |

|
Sulfur (S) |
≤0.015 |
Strictly controlled to avoid hot working defects and performance degradation |
|
Phosphorus (P) |
≤0.030 |
Limited to prevent brittleness in high-temperature service |
Mechanical Properties: Reliable Strength Across Temperature Ranges
What distinguishes UNS N08810 is its ability to retain mechanical strength under extreme thermal stress—a critical advantage for components operating in cyclic or sustained high-temperature conditions. Our hot-rolled and forged bars maintain consistent performance from room temperature to 1100°C.

Unmatched Performance Advantages
1. Exceptional High-Temperature Stability
Engineered to operate continuously at 600-1000°C (with short-term resistance up to 1100°C), UNS N08810 resists thermal softening that plagues conventional stainless steels. Its stabilized austenitic structure prevents phase transformations even after thousands of hours of high-heat exposure.
2. Superior Corrosion Resistance
The high chromium content forms a self-healing oxide layer that protects against industrial flue gases, high-temperature steam, and sulfur-containing media. It also resists carburization in carbon-rich environments, avoiding embrittlement and structural failure.
3. Reliable Creep Resistance
Optimized carbon and Al+Ti content deliver exceptional resistance to creep—slow plastic deformation under sustained heat and stress—making it ideal for long-service-life components like boiler tubes and heat exchanger .
4. Excellent Processability
Despite its high performance, UNS N08810 maintains good weldability (with matching high-nickel-chromium electrodes) and machinability. Post-weld heat treatment enhances joint strength to match base material properties.
Typical Applications
Our UNS N08810 round bars are trusted in industries where failure is not an option:
-
Energy/Nuclear: High-temperature steam pipes, reactor auxiliary components, boiler superheaters
-
Petrochemical: Ethylene ,high-temperature reaction vessels, catalytic reformer tubes
-
Metallurgy: Heat treatment furnace radiating tubes, annealing 炉 components
-
Oil & Gas: Downhole high-temperature pipes, wellhead equipment
Quality Assurance & Compliance
All bars undergo strict quality control, including:
-
Chemical composition analysis (spectrometric testing)
-
Mechanical property verification (tensile, impact testing)
-
Non-destructive inspection (ultrasonic testing per ASTM A388)
-
Dimensional accuracy verification
-
Supply with ISO 9001-certified Material Test Certificates (MTC)
Customization Options
-
Diameters: 10mm to 350mm (custom sizes available upon request)
-
Lengths: 3-6m random lengths or fixed lengths up to 12m
-
