Dhruv Metals produces and supplies high-performance Hastelloy Forgings in Hyderabad, India, from corrosion-resistant nickel-based alloys like Hastelloy C-22, C-276, and B2. Famed for their superior resistance to severe chemical environments, including oxidizers, chlorides, and acids, Hastelloy forgings are employed in very critical industries. Dhruv Metals offers forged components with improved mechanical properties and close dimensional tolerance, suitable for application in chemical reactors, pressure vessels, heat exchangers, and marine equipment. All forgings are heat-treated and tested as per ASTM B564 and other international standards.
Hastelloy C-276 contains ~57% Nickel, 15–17% Molybdenum, 14.5–16.5% Chromium, and 3–4.5% Iron with minor trace amounts of W, Co, and Mn. Tensile strength is approximately 690–785 MPa, yield strength ~283–345 MPa, and elongation 40–45%. These forgings are pitting, stress corrosion cracking, and oxidizing/reducing agents resistant. They show high performance in a broad temperature range and preserve their toughness at cryogenic and elevated temperatures. The forged structure provides grain refining and structural integrity for severe industrial applications.

To improve the surface finish of Hastelloy forgings, use techniques like polishing, grinding, or shot peening. Additionally, chemical or electrochemical cleaning can remove surface contaminants and enhance smoothness.
The most suitable forging techniques for Hastelloy include open-die forging and closed-die forging, which ensure optimal material flow and minimize defects. These methods provide the necessary strength and precision for high-performance applications.
To determine if Hastelloy forgings meet your needs, evaluate their chemical composition, mechanical properties, and corrosion resistance in your specific operating conditions. Conduct material testing or consult with suppliers for tailored solutions based on your application requirements.
Hastelloy Forgings find extensive applications in chemical processing equipment, scrubbers, evaporators, and reactor vessels, which process aggressive fluids like hydrochloric acid, sulfuric acid, and hypochlorite. They are applied in containment equipment, waste treatment units, and heat exchangers in nuclear and marine applications. Their high formability and resistance to corrosion also recommend their use in pharmaceutical reactors, paper and pulp bleach plants, and flue gas scrubbers. Dhruv Metals offers forged Hastelloy components ready for high-integrity use in tough industrial applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
