ASTM GB DIN EN Standard Incoloy 800 / 800H / 800HT Nickel Alloy Round Bars
Incoloy 800, 800H, and 800HT are a family of nickel-iron-chromium alloys renowned for their exceptional high-temperature strength, excellent oxidation and carburization resistance, and superior corrosion resistance in various aggressive environments. These round bars, manufactured in compliance with international standards such as ASTM, GB, DIN, and EN, are widely used in high-temperature industrial applications where reliability and durability are critical. While the three alloys share a similar base composition, they differ primarily in carbon content and heat treatment processes, resulting in distinct mechanical properties tailored to specific temperature ranges and load requirements.
1. Chemical Composition (Weight %)
The chemical composition of Incoloy 800, 800H, and 800HT adheres to strict international standards, ensuring consistency and performance. The key elements and their typical ranges are as follows:
Note: The slight increase in carbon content from Incoloy 800 to 800HT enhances high-temperature creep strength, making 800HT suitable for the most demanding heat-resistant applications.
2. Mechanical Properties
The mechanical properties of these nickel alloy round bars are optimized through controlled heat treatment (e.g., solution annealing and aging), ensuring they meet the requirements of high-temperature and high-stress environments. The following values are typical for annealed round bars (tested at room temperature unless specified otherwise):
Key Advantage: Incoloy 800HT exhibits the highest creep strength among the three alloys, enabling it to withstand prolonged exposure to temperatures up to 1100°C (2012°F) without significant deformation.
3. Executive Standards
The production and quality control of Incoloy 800 / 800H / 800HT nickel alloy round bars comply with major international and national standards, ensuring compatibility with global industrial requirements. The most commonly referenced standards include:
- ASTM (American Society for Testing and Materials):
- ASTM B408: Standard Specification for Nickel-Iron-Chromium Alloy (UNS N08800, N08810, N08811) Rod and Bar
(Note: UNS N08800 = Incoloy 800; UNS N08810 = Incoloy 800H; UNS N08811 = Incoloy 800HT)
- GB (Chinese National Standard):
- GB/T 15007: Nickel-Based Alloy Rods and Bars
- GB/T 20412: Nickel and Nickel Alloy Wrought Products
- DIN (German Institute for Standardization):
- DIN 17744: Nickel and Nickel Alloy Rods and Bars
(Designation: NiCr20Fe (Incoloy 800); NiCr20FeSi (Incoloy 800H/800HT))
- EN (European Standard):
- EN 10095: Nickel and Nickel Alloy Wrought Products — Technical Delivery Conditions
(Designation: NiCr20Fe (Incoloy 800); NiCr20FeSi (Incoloy 800H/800HT))
All round bars undergo strict quality inspections, including chemical composition analysis, mechanical property testing, dimensional accuracy checks, and non-destructive testing (NDT) such as ultrasonic testing (UT) to ensure no internal defects.
4. Equivalent Grades
In addition to the Incoloy brand names, these nickel alloys have equivalent designations in different regional and industrial standards, facilitating material selection and substitution across global markets:
Note: While these grades are chemically and mechanically equivalent, slight variations in processing may exist between manufacturers. It is recommended to confirm compatibility with specific application requirements before substitution.
5. Applications
Leveraging their excellent high-temperature performance, corrosion resistance, and mechanical stability, Incoloy 800 / 800H / 800HT round bars are widely used in the following industries and applications:
- Thermal Power Generation: Boiler tubes, superheater tubes, steam headers, and turbine components (especially Incoloy 800H/800HT for high-pressure, high-temperature steam systems).
- Petrochemical & Refining: Catalytic reformer tubes, hydrogenation reactors, and furnace parts (resistant to hydrogen embrittlement and high-temperature hydrocarbon corrosion).
- Chemical Processing: Reactors, heat exchangers, and piping for handling acidic solutions, molten salts, and oxidizing gases (e.g., sulfuric acid, nitric acid environments).
- Aerospace & Aviation: Engine components, exhaust systems, and thermal barriers (used in moderate-temperature sections of jet engines).
- Nuclear Energy: Fuel cladding, reactor core components, and heat exchangers (Incoloy 800 is preferred for its low cobalt content and radiation resistance).
- Metallurgical Industry: Furnace linings, heating elements, and annealing baskets (resistant to oxidation and carburization at high temperatures).
The choice between the three alloys depends on the application temperature: Incoloy 800 is suitable for temperatures up to 900°C (1652°F), 800H for up to 1000°C (1832°F), and 800HT for the highest temperatures up to 1100°C (2012°F).
