Rupal Metals is a well-known manufacturer and supplier in Delhi, India, providing high-quality Hastelloy Forgings for various industrial uses. Having years of experience and maintaining a commitment to excellence, Rupal Metals provides forged products that are up to international standards. Our Hastelloy Forgings are highly resistant to corrosion and therefore suitable for severe conditions. We serve a broad industry base with tailor-made solutions that are high in performance and durability. Dedicated to quality, accuracy, and customer satisfaction, Rupal Metals has emerged as a reliable name in supplying accurate and efficient Hastelloy Forgings in India and overseas.
. Hastelloy Forgings consist mainly of nickel, molybdenum, chromium, iron, and cobalt, depending on the grade like C22, C276, or X. These alloys have good corrosion resistance, particularly under oxidizing and reducing conditions. They have high tensile strength (up to 690 MPa), good elongation (up to 40%), and superior impact strength. Their mechanical integrity is retained even under high thermal stress and pressure, and they are thus used in very demanding applications. Their strong composition and strength ensure durability and operational safety under harsh chemical and high-temperature conditions.

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 are extensively utilized in applications where high corrosion resistance and strength are essential. They are found in chemical processing, marine, aerospace, nuclear power, and petrochemical industries. In such environments, Hastelloy Forgings are used in reactor vessels, heat exchangers, pump shafts, flanges, valves, and manifolds. Their corrosion resistance to aggressive media like chlorides, sulfuric acid, and high-temperature oxidants makes them suitable for harsh applications. In addition, their superior fabrication and weldability characteristics further improve their use in special applications demanding durability, accuracy, and immunity to mechanical and chemical degradation.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
