George Metals, located in Houston, USA, is a reliable manufacturer and supplier known for its top-notch Inconel Hollow Bars. These bars are designed to offer outstanding strength, resistance to oxidation, and performance in the toughest environments. They’re crafted to meet strict ASTM, ASME, and international standards, and come in various grades like Inconel 600, 601, 625, 718, and 825. With a selection of outside diameters, wall thicknesses, and lengths, these hollow bars cater to the demands of high-temperature, high-pressure, and corrosive applications. Industries such as aerospace, oil and gas, power generation, and chemical processing trust George Metals for their quality and technical know-how.
Inconel Hollow Bars are made from nickel-based alloys, containing around 58–72% nickel and 14–23% chromium, depending on the specific grade, along with elements like molybdenum, niobium, and iron. For instance, Inconel 625 is enriched with molybdenum and niobium, enhancing its strength and corrosion resistance. The tensile strength varies from about 690 MPa for Inconel 600 to over 1,100 MPa for Inconel 718. These alloys excel in creep resistance, fatigue strength, and stability at temperatures above 1,000 °C. They also resist oxidation, carburization, chloride stress corrosion cracking, and pitting, making them reliable in harsh thermal and chemical conditions.

Inconel Hollow Bars find their place in critical applications that demand high strength and corrosion resistance at elevated temperatures. Aerospace manufacturers often specify them for turbine components, exhaust systems, and heat shields. In the oil and gas sector, they’re used in downhole tools, completion equipment, and offshore risers that face sour gas and chlorides. Power generation facilities depend on Inconel for boiler tubing, superheater parts, and heat exchangers that undergo thermal cycling. Chemical processing plants utilize these hollow bars in reactor vessels and acid handling systems, ensuring durability and performance in challenging environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
