Dhruv Metals supplies corrosion-resistant Hastelloy Hollow Bars in grades like C-22 and C-276, ideal for chemical, marine, and high-temperature industries. Our bars are produced using precise techniques to ensure uniform wall thickness and concentricity, which guarantees reliability under pressure and corrosive exposure. Hastelloy hollow bars are perfect for machining into pressure vessels, valve parts, and pump shafts. We ensure that our hollow bars have an excellent finish and comply with ASTM B619 and related standards.
Hastelloy C-276 contains about 57% nickel, 16% molybdenum, 15% chromium, 5% iron, and trace amounts of tungsten and cobalt. The tensile strength ranges from 690 to 785 MPa; yield strength is 280 to 345 MPa; and elongation is around 40%. It offers great resistance to both oxidizing and reducing agents, including chlorides, hypochlorites, and sulfur compounds. Hollow bars maintain their mechanical integrity at both elevated and cryogenic temperatures. Their seamless structure supports high-stress environments and reduces machining waste during production.

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@dhruvmetals.co.in
Hastelloy Hollow Bars are ideal for pump sleeves, heat exchanger parts, chemical injectors, and condenser tubes. They are widely used in desalination plants, pharmaceutical reactors, marine hardware, and nuclear waste processing units. In aggressive chemical environments, these bars resist stress corrosion cracking, pitting, and acid attacks. Engineers prefer them for valve spools, shaft sleeves, and pressure tube fittings where failure is not an option. Dhruv Metals ensures that each hollow bar meets industry-specific requirements.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
