Nickel alloy tubes

Nickel’s high solubility with other metals allows for the creation of many nickel alloys with a variety of uses.

Nickel’s versatility is one of its most valuable attributes, primarily due to its ability to form alloys with a wide range of metals. Its high solubility with copper, iron, and chromium enables the creation of numerous alloy combinations, each offering unique properties.

This adaptability makes nickel an essential component in developing specialized materials for diverse applications, from corrosion-resistant alloys used in marine environments to high-strength alloys in aerospace and industrial settings.

N08800 – Iron-nickel-chromium alloy 800 – BS 3074NA15

Iron-nickel-chromium alloy 800 (UNS N08800) is particularly valued for tube applications due to its excellent strength and resistance to oxidation and carburization in high-temperature environments. These properties make it ideal for use in heat exchanger and furnace tubes, where prolonged exposure to extreme heat is common.

The alloy’s stability in its austenitic structure ensures that it maintains its integrity and performance over long durations, even under severe thermal conditions. Additionally, alloy 800’s resistance to corrosion in various aqueous environments further enhances its suitability for demanding tube applications in industries such as power generation, chemical processing, and petrochemical plants.
