Incoloy 825 Round Bar is a corrosion-resistant nickel-iron-chromium alloy enriched with additions of molybdenum, copper, and titanium, designed to offer exceptional resistance to a wide range of corrosive environments. Known for its outstanding performance in both oxidizing and reducing conditions, Incoloy 825 Round Bar is extensively used in industries such as chemical processing, marine engineering, acid production, and pollution control. Labdhi Metals, a trusted manufacturer, stockist, and exporter, delivers Incoloy 825 Round Bars with precise tolerance, excellent finish, and superior quality for critical industrial applications.
One of the most notable features of Incoloy 825 Round Bar is its resistance to sulfuric and phosphoric acids, making it an ideal material for use in heat exchangers, condenser tubing, pickling equipment, and chemical tanks. The molybdenum component enhances resistance to pitting and crevice corrosion, while copper improves performance in sulfuric acid environments. Labdhi Metals ensures that its round bars are processed with strict adherence to international standards like ASTM B425, offering both hot-rolled and cold-drawn variants to meet different mechanical and dimensional requirements.
In terms of mechanical stability, Incoloy 825 provides good strength and excellent toughness across a wide temperature range, from cryogenic to moderately elevated temperatures. The alloy’s ability to resist chloride-induced stress corrosion cracking and intergranular corrosion even after sensitization makes it highly reliable for long-term service. Labdhi Metals maintains a large inventory of Incoloy 825 Round Bar in various diameters and lengths, enabling quick turnaround for urgent project requirements.
These round bars are widely supplied in annealed and solution-annealed conditions with precise surface finishes such as bright, black, or centerless ground. Labdhi Metals also offers value-added services including cutting, machining, and third-party inspections (TPI). Every bar is accompanied by complete documentation, including Mill Test Certificates (MTC) as per EN 10204 3.1/3.2 standards, chemical test reports, and dimensional inspection results.
