Inconel 600

Chemical properties

Inconel 600 is a nickel‑based alloy with nickel as the highest content element (approximately 72–76 wt.%), and its major alloying additions are chromium (14–17%), iron (6–10%), and small amounts of manganese, silicon, and copper.

Each element contributes specific performance benefits. Nickel (72–76%) provides a stable austenitic matrix, ensuring excellent ductility, good fabricability, and outstanding resistance to chloride‑induced stress corrosion cracking and to many caustic and alkaline media. Chromium (14–17%) delivers strong resistance against high‑temperature oxidation, carburization, and sulfidation, as well as against oxidizing acids such as nitric acid. Iron (6–10%) helps improve mechanical strength at elevated temperatures while maintaining good workability. The high nickel content also gives Inconel 600 exceptional resistance to chloride ion stress corrosion cracking, even at elevated temperatures. This balanced composition makes Inconel 600 suitable for service from cryogenic to approximately 1095°C (2000°F) under oxidizing and reducing conditions.

Viaken supplies Inconel 600 in three key forms: tubes/pipes, coiled strip, and plates/sheets.

Typical application fields and the corresponding uses of each form are listed below:

1.Chemical processing industry

Tubes/pipes – Heat exchanger tubing and process piping handling caustic soda, chlorine, and organic acids.

Coiled strip – Linings for reaction vessels, expansion joints, and gaskets.

Plates – Storage tanks, evaporators, and soap manufacturing equipment.
