Product Description
ASTM B407 Incoloy 800H (UNS N08810) Nickel Alloy Seamless Pipe
This high-performance seamless pipe is manufactured from Incoloy 800H (UNS N08810) nickel-iron-chromium alloy, fully compliant with ASTM B407 standards. Engineered specifically for demanding high-temperature applications above 593°C (1100°F), it delivers superior resistance to creep, rupture, oxidation, and corrosion.
Product Specifications & Standards
ASTM B407 covers cold-worked and hot-finished annealed seamless pipe and tube requirements, ensuring strict adherence to chemical composition, mechanical properties, heat treatment, and non-destructive testing standards. The controlled grain size and annealed condition optimize performance in extreme temperature environments.
Chemical Composition
Incoloy 800H features a precisely balanced austenitic composition that provides exceptional high-temperature strength and corrosion resistance:
| Element | Composition (% by weight) | Role/Effect |
|---|---|---|
| Nickel (Ni) | 30.0 - 35.0 | Base element; provides high-temperature strength, ductility, and resistance to reducing atmospheres |
| Chromium (Cr) | 19.0 - 23.0 | Imparts oxidation and corrosion resistance by forming protective Cr₂O₃ scale |
| Iron (Fe) | Balance (approx. 39.5% min) | Balances cost and contributes to alloy strength |
| Carbon (C) | 0.05 - 0.10 | Carefully controlled to enhance high-temperature creep strength |
| Aluminum (Al) | 0.15 - 0.60 | Improves high-temperature oxidation resistance and strengthens the alloy |
| Titanium (Ti) | 0.15 - 0.60 | Works with Al to form strengthening phases and stabilize structure |
| Manganese (Mn) | ≤ 1.50 | Aids in deoxidation during manufacturing |
| Silicon (Si) | ≤ 1.00 | Improves oxidation resistance |
| Copper (Cu) | ≤ 0.75 | - |
| Sulfur (S) | ≤ 0.015 | Controlled impurity to maintain weldability and hot workability |
Mechanical & Physical Properties
Delivered in annealed condition with the following minimum room-temperature properties:
| Property | Minimum Value | Condition / Notes |
|---|---|---|
| Tensile Strength | 450 MPa (65,000 psi) | For hot-finished annealed or cold-worked annealed material |
| Yield Strength (0.2% Offset) | 170 MPa (25,000 psi) | - |
| Elongation | 30% | - |
| Density | 8.0 g/cm³ | - |
| Melting Range | 1350 - 1400 °C | - |
High-Temperature Performance: Excellent long-term strength at elevated temperatures with superior oxidation resistance up to 1100°C. Maintains stability in carburizing and sulfidizing atmospheres common in industrial furnace environments.
