Inconel Square Bars are generally made up of nickel (at least 58%), chromium (around 20-23%), iron, molybdenum, cobalt, and trace elements. These bars showcase remarkable tensile strength (at least 100 ksi), high yield strength, and excellent creep resistance at elevated temperatures. The alloy’s ability to resist oxidation and corrosion is impressive, particularly in acidic and high-temperature settings. Inconel maintains its structural integrity even under thermal cycling and mechanical stress, making it perfect for critical applications. These bars can be solution-annealed and cold-worked to enhance hardness and ensure precise dimensions.
