As a trusted Incoloy 800H pipe fittings manufacturer and exporter, we supply premium-quality fittings that meet international standards and demanding application requirements. Our product range includes elbows, tees, reducers, stub ends, and caps engineered for superior mechanical strength, oxidation resistance, and long-term performance at elevated temperatures.
What is Incoloy 800H?
Incoloy 800H is a nickel-chromium-iron alloy known for its excellent strength and resistance to oxidation and carburization at high temperatures. It is a controlled-carbon version of Incoloy 800, developed specifically for applications requiring enhanced creep and rupture strength above 600°C.
The “H” grade designation indicates a higher carbon content, which improves the alloy’s mechanical stability in prolonged high-temperature service. Incoloy 800H is commonly used in pressure vessels, heat exchangers, furnace components, and piping systems where conventional stainless steels may fail.
This alloy complies with internationally recognized standards such as ASTM B366 / ASME SB366 for pipe fittings, ensuring reliability and global acceptance.
Chemical Composition & Mechanical Properties
Chemical Composition of Incoloy 800H
Incoloy 800H is carefully balanced to deliver exceptional performance:
| Nickel (30–35%) | Provides resistance to oxidation and carburization |
| Chromium (19–23%) | Enhances corrosion and oxidation resistance |
| Iron (Balance) | Adds structural strength |
| Carbon (0.05–0.10%) | Improves creep resistance at high temperatures |
This composition allows Incoloy 800H pipe fittings to maintain strength and integrity during continuous thermal exposure.
Mechanical Properties
Key mechanical characteristics include:
- High tensile and yield strength
- Excellent creep and stress-rupture resistance
- Good ductility and toughness
- Stable microstructure at elevated temperatures
These properties make Incoloy 800H fittings ideal for long-term service in harsh industrial conditions.
Manufacturing Process of Incoloy 800H Pipe Fittings
As a specialized Incoloy 800H pipe fittings manufacturer, we follow a stringent manufacturing process to ensure consistent quality and performance.
The process begins with careful raw material selection from certified sources. The material is then hot-formed or cold-formed into the required fitting shapes, such as elbows, tees, and reducers. Precision forming ensures accurate dimensions and smooth flow characteristics.
After forming, the fittings undergo solution annealing and heat treatment to restore metallurgical properties and relieve internal stresses. Machining and surface finishing are carried out to achieve tight tolerances and excellent surface quality.
Each fitting is subjected to comprehensive inspection and testing before dispatch, ensuring compliance with ASTM, ASME, and customer-specific requirements.
