Inconel 601 Nickel Alloy Pipe (UNS N06601)

Inconel 601 is a nickel-chromium-iron solid-solution strengthened alloy; the addition of 1.0–1.7% aluminum significantly enhances the material's high-temperature oxidation resistance.

Alloy 601 exhibits excellent resistance to oxidation, carburization, and corrosion in sulfur-bearing atmospheres at high temperatures, while maintaining good mechanical properties at both room and elevated temperatures; it is also easy to form, machine, and weld.

Inconel 601 tubing specifications can be customized; the outer diameter generally ranges from 12 mm to 100 mm, wall thicknesses cover Sch 40 to Sch 80 ratings, and lengths can be supplied according to requirements.

The data is based on the ASTM B167 standard specification.

Here are its specific advantageous operating conditions and the limitations that need to be noted:

 

Ideal operating condition

Ultra-high temperature oxidation environment

Carburizing and sulfur-containing atmosphere

High strength and creep resistance

Operating conditions restrictions and prohibitions

Strongly reducing properties and high-sulfur environments

Specific temperature range(600℃-800℃)

Strongly acidic environment

• Excellent high-temperature oxidation resistance (up to 1250°C): The synergistic effect of aluminum and chromium forms a dense oxide layer that resists spalling caused by thermal cycling, making it suitable for demanding environments such as high-temperature furnace tubes and heat treatment equipment.

• Superior resistance to carburization and nitriding: Maintains microstructural stability in carburizing atmospheres, making it an ideal choice for chemical cracking tubes, radiant tubes, and carburizing furnace components.

• Resistance to corrosion in sulfur-bearing atmospheres: High chromium and aluminum content ensures good oxidation resistance in high-temperature, sulfur-containing environments.

• High-temperature strength and creep resistance: Retains good mechanical strength and resistance to creep deformation at temperatures above 500°C. Even after prolonged exposure at 1120°C, it retains approximately 80% of its room-temperature yield strength.

• Good fabricability and weldability: Can be joined using standard welding processes (such as TIG and MIG) without the need for post-weld heat treatment, making it suitable for on-site installation.
