Material Description

UNS N08810 (Alloy 800H) stands 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 bars deliver unmatched stability and durability for critical industrial components.

Core Chemical Composition

Element	Content Range (%)	Key Function
Nickel (Ni)	30.0 - 35.0	Maintains austenitic matrix stability; prevents embrittlement at high temperatures
Chromium (Cr)	19.0 - 23.0	Forms dense CrO oxide film; resists oxidation and high-temperature corrosion
Iron (Fe)	Balance	Reduces material cost while preserving processability
Carbon (C)	0.05 - 0.10	Enhances creep and rupture strength via carbide formation
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
Manganese (Mn)	≤1.50	Acts as deoxidizer; minimizes residual impurities
Sulfur (S)	≤0.015	Strictly controlled to avoid hot working defects
Phosphorus (P)	≤0.030	Limited to prevent brittleness in high-temperature service

Mechanical Properties

Performance Metric	Room Temperature (Min.)	At 800°C (Min.)
Tensile Strength (Rm)	450 MPa	200 MPa
Yield Strength (Rp0.2)	180 MPa	100 MPa
Elongation (A5)	35%	25%
Density	7.9 g/cm³	7.8 g/cm³
Melting Point	1300 - 1350°C	-

Hot Rolled vs. Forged Bars

Feature	Hot Rolled Bars	Forged Bars
Processing Method	Continuous rolling at 1100-1200°C	Precision forging with controlled plastic deformation
Surface Finish	Black oxide scale (can be lightly ground)	Smooth, often turned/ground; minimal surface defects
Dimensional Tolerance	±0.5mm	±0.2mm
Microstructure	Coarse but uniform austenitic grains	Refined grain structure; eliminated internal porosity
Key Advantages	Cost-effective; efficient for standard applications	Superior creep resistance; uniform transverse/longitudinal strength
Ideal Applications	Flanges, valves, non-critical shafts	High-pressure turbine components, nuclear reactor parts

Performance Advantages

Exceptional High-Temperature Stability
Operates continuously at 600-1000°C with short-term resistance up to 1100°C. Prevents thermal softening and phase transformations.

Superior Corrosion Resistance
High chromium content forms self-healing oxide layer protecting against industrial flue gases, steam, and sulfur-containing media.

Reliable Creep Resistance
Optimized carbon and Al+Ti content deliver exceptional resistance to plastic deformation under sustained heat and stress.

Excellent Processability
Maintains good weldability and machinability despite high performance. Post-weld heat treatment enhances joint strength.

Typical Applications

Energy/Nuclear: High-temperature steam pipes, reactor auxiliary components, boiler superheaters
Petrochemical: Ethylene production, high-temperature reaction vessels, catalytic reformer tubes
Metallurgy: Heat treatment furnace radiating tubes, annealing components
Oil & Gas: Downhole high-temperature pipes, wellhead equipment

Quality Assurance & Compliance

Chemical composition analysis (spectrometric testing)
Mechanical property verification (tensile, impact testing)
Non-destructive inspection (ultrasonic testing per ASTM A388)
Dimensional accuracy verification
ISO 9001-certified Material Test Certificates (MTC)

Customization Options

Diameters: 10mm to 350mm (custom sizes available)
Lengths: 3-6m random lengths or fixed lengths up to 12m
Surface Treatments: Black oxide, ground, or bright finish
Delivery Condition: Solution-annealed (standard) or as-specified heat treatment

Whether for routine industrial use or mission-critical applications, our UNS N08810 Alloy 800H round bars deliver the reliability and performance required in the world's harshest high-temperature environments. Contact us for material certificates, technical data sheets, or customized quotations.
