Hot Rolled & Cold Drawn Incoloy 800H Round Bar UNS N08810 Nickel Alloy Bright Bars with Diameter 5-350mm and Corrosion Resistance

UNS N08810, commonly designated as Incoloy 800H, is a premium nickel-iron-chromium alloy round bar engineered for exceptional performance in high-temperature and corrosive environments. Available in hot rolled and cold drawn (bright bar) variants, this alloy combines robust mechanical strength, superior corrosion resistance, and structural stability—making it a cornerstone material in industries demanding reliability under extreme conditions.

The exceptional performance of UNS N08810 stems from its precisely balanced chemical composition and austenitic face-centered cubic lattice structure. Its controlled carbon content (0.05-0.10%) and optimized aluminum-titanium ratio enhance creep resistance and structural stability at elevated temperatures.

• Hot Working: Processable at 871-1232°C for forging, bending, and shaping
• Cold Working: Cold drawing enhances surface finish and dimensional accuracy
• Welding: Compatible with standard stainless steel welding techniques
• Machining: Machinable with carbide tools; coolant use recommended

• Chemical & Petrochemical: Sulfur-containing atmosphere equipment, condensers, and tubes
• Power Generation: Heat exchanger tubes, steam generator components, and gas turbine parts
• Nuclear Industry: Condenser systems and reactor auxiliary piping
• Manufacturing: Furnace fixtures, carburizing equipment, and heating element sheathing

Our UNS N08810 round bars adhere to global industry standards including ASTM B408 and ASME SB408. Each batch undergoes rigorous testing:

• Chemical analysis via X-ray fluorescence (XRF)
• Mechanical testing (tensile, yield, elongation)
• Non-destructive testing (ultrasonic for internal defects)
• Dimensional inspection with precision calipers

Compared to similar alloys like UNS N08811 (Incoloy 800HT), UNS N08810 offers a cost-effective balance of performance for applications below 700°C. Its resistance to sulfur-containing atmospheres makes it preferable to 304 stainless steel in chemical processing applications.

Whether your project requires the cost-efficiency of hot rolled bars or the precision of cold drawn bright bars, UNS N08810 (Incoloy 800H) round bars provide reliable performance in challenging environments.
