Rupal Metals, located in Delhi, India, has built a solid reputation as a reliable manufacturer and supplier of Hastelloy B2 Forgings. They provide top-notch corrosion-resistant solutions for industries that deal with harsh chemical environments. Renowned for their quality, precision, and dependability, Rupal Metals caters to sectors like chemical processing, marine, pharmaceuticals, and energy. Hastelloy B2, a nickel-molybdenum alloy, is specifically engineered to resist hydrochloric acid and other strongly reducing agents. With state-of-the-art forging facilities and rigorous quality control measures, Rupal Metals consistently delivers high-performance Hastelloy B2 forgings that align with global industry standards and meet the unique needs of their clients.
Hastelloy B2 Forgings are primarily made up of Nickel (about 69%) and Molybdenum (around 28–30%), along with trace amounts of Iron, Cobalt, Chromium, and other elements. This alloy is known for its exceptional resistance to hydrochloric, acetic, and sulfuric acids. In terms of mechanical properties, it boasts a tensile strength of roughly 760 MPa, a yield strength of about 355 MPa, and an elongation of nearly 40%. Hastelloy B2 is also recognized for its excellent ductility and thermal stability, maintaining its mechanical integrity over a wide temperature range. Its low carbon content helps reduce carbide precipitation during welding, which enhances corrosion resistance in heat-affected zones, ensuring a long service life even in tough conditions.

To determine if Hastelloy B2 forgings meet your needs, evaluate their resistance to corrosion in aggressive chemical environments and their mechanical properties at the operating temperature. Perform tests such as tensile, impact, and corrosion resistance tests for assurance.
The forging process for Hastelloy B2 typically takes several hours, depending on the complexity of the part and the size of the material. It includes heating, shaping, cooling, and any necessary post-forging treatments.
The ideal temperature range for forging Hastelloy B2 is between 2,100°F and 2,300°F (1,149°C to 1,260°C). This range ensures optimal material flow and avoids excessive grain growth.
Hastelloy B2 Forgings find extensive applications in industries that demand exceptional resistance to aggressive chemical environments. In chemical processing, they are commonly used in reactors, heat exchangers, distillation columns, and pressure vessels that handle hydrochloric acid and other reducing media. The pharmaceutical and food processing sectors depend on Hastelloy B2 for equipment that is both sanitary and corrosion-resistant. In marine and offshore engineering, it’s utilized for piping, pumps, and valves that come into contact with brine and acidic fluids. Its weldability further enhances its appeal in these demanding applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
