Alloy 601 Round Bar Nickel Alloy Bar UNS N06601 Inconel 601 Round Bar

Alloy 601 Round Bar is a high-performance nickel-chromium alloy renowned for its exceptional oxidation resistance, high-temperature strength, and excellent mechanical properties. Below is a detailed description of its composition, characteristics, and applications:

Composition

Alloy 601 is primarily composed of:

• Nickel (Ni): 58-63% – Provides excellent corrosion resistance and high-temperature strength.

• Chromium (Cr): 21-25% – Enhances oxidation and corrosion resistance.

• Iron (Fe): Balance – Forms the base of the alloy.

• Aluminum (Al): 1.0-1.7% – Improves oxidation resistance by forming a protective oxide layer.

• Other Elements: Small amounts of silicon (Si), manganese (Mn), and copper (Cu) may also be present.
