Sahil Metals is a renowned Riyadh, Saudi Arabia-based manufacturer and supplier with a track record of delivering cutting-edge metal solutions for all-important industrial requirements. A top specialty offered by one of its products is Hastelloy hollow bars, engineered to be strong, corrosion-resistant, and easily machined. These empty bars are commonly applied in chemical processing, pharmaceuticals, marine engineering, and power generation industries. Sahil Metals makes sure that all Hastelloy products are as per global standards of quality, providing strength, performance, and accuracy. With prompt service and guaranteed delivery, the company assists clients with high-quality materials for the most challenging environments.
Hastelloy hollow bars are nickel-based alloys with grades such as C22, C276, B2, and B3, having the main elements being molybdenum, chromium, iron, cobalt, and tungsten. The bars have good resistance against oxidizing and reducing chemicals and possess high tensile strength (of around 690–800 MPa). The bars are resistant to pitting, crevice corrosion, and stress corrosion cracking even in highly corrosive or chloride-based environments. Their open-holed construction facilitates minimized machining, material cost savings, and increased component efficiency with maintained mechanical stability against thermal and chemical stress.

Yes, Hastelloy hollow bars can be heat-treated to enhance their mechanical properties, such as strength and toughness. However, specific heat treatment conditions depend on the alloy grade.
The pressure rating of Hastelloy hollow bars depends on their size, wall thickness, and alloy grade. It is crucial to consult specific material standards and perform engineering calculations for accurate ratings.
Yes, we provide Hastelloy Hollow Bars in standard and customized dimensions and polishes to meet your specific project requirements. For more details mail us on sales@sahilmetals.com
Hastelloy hollow bar is employed where corrosion resistance along with a cylindrical or tubular form is necessary for pressure-bearing or fluid-handling applications. Typical applications are pump shafts, heat exchanger tubes, sleeve parts, and reactor internals in chemical, petrochemical, and marine systems. The hollow structure offers manufacturing flexibility with reduced material waste and machining time. Engineers trust Hastelloy hollow bars with their performance under highly corrosive conditions to provide structural integrity, decreased downtime, and safe operation in critical service applications.
