FAQ's
What is the difference between Incoloy 800 and Incoloy 800H?
What is the difference between Incoloy 800 and Incoloy 800H?
The primary difference lies in the carbon content and the required solution heat treatment and grain size for Incoloy 800H. Incoloy 800H has a controlled, higher carbon content (0.05–0.10%) compared to Incoloy 800 (0.10% maximum with no lower limit). This controlled composition, along with a high-temperature anneal, gives Incoloy 800H significantly greater creep and stress-rupture strength at temperatures above 1100°F (600°C), making it superior for high-temperature structural applications. In addition, 800H is required to have a coarser average grain size.
How do Incoloy 800H Seamless Tubes perform in high-temperature environments?
How do Incoloy 800H Seamless Tubes perform in high-temperature environments?
Incoloy 800H Seamless Tubes offer excellent high-temperature performance. They are solid-solution strengthened nickel-iron-chromium alloys specifically designed for service in the 1100°F to 1800°F (593°C to 982°C) range. Their controlled composition and heat treatment provide superior creep and stress-rupture strength compared to Alloy 800. They also exhibit excellent resistance to oxidation, carburization, and sulfidation at elevated temperatures.

What is the chemical composition of an incoloy 800h tube?
What is the chemical composition of an incoloy 800h tube?
Incoloy 800H is a nickel-iron-chromium alloy. Its key composition includes Nickel (30.0–35.0%), Chromium (19.0–23.0%), and a minimum Iron content of 39.5%. The critical controlled elements that distinguish it are Carbon (0.05–0.10%), Aluminum (0.15–0.60%), and Titanium (0.15–0.60%), with the total Aluminum plus Titanium content controlled to 0.30–1.20%.
What is the incoloy 800h tube used for?
What is the incoloy 800h tube used for?
Incoloy 800H tubes are primarily used in high-temperature structural applications where resistance to creep and stress rupture is essential. Typical uses include heat exchanger tubes, process piping, superheater and reheater tubing in power plants, and various components within industrial furnaces like radiant tubes, muffles, and retorts, especially where thermal cycling and corrosive high-temperature atmospheres are present.
What is the heat treatment for an incoloy 800h tube?
What is the heat treatment for an incoloy 800h tube?
Incoloy 800H tubes are typically supplied in a solution-annealed condition. This involves a high-temperature anneal, often at 2050°F (1121°C) minimum, followed by rapid cooling. This specific heat treatment is crucial as it controls the grain size, which combined with the controlled carbon content, optimizes the alloy’s creep and stress-rupture properties for high-temperature service.
