Based in Hamilton, New Zealand, Hemi Metals has built a strong reputation for delivering high-performance materials to demanding industries worldwide. Our expertise shines with products like Hastelloy C276 forgings, where we expertly guide the metal through the forging process. This careful, hands-on approach results in incredibly strong and reliable components, perfectly suited for the harshest chemical and marine environments. We take pride in offering not just a product, but a dependable, locally-made solution for critical applications.
Hastelloy C276 is a nickel-molybdenum-chromium alloy known for its exceptional resistance to a wide range of severe corrosives. Its composition gives it remarkable strength and toughness, especially when formed through the forging process. This creates a dense, uniform grain structure that enhances its mechanical properties, resulting in components that can withstand high stresses and extreme temperatures without losing their integrity, making them a trusted choice for engineers.

Post-forging operations for Hastelloy C276 include heat treatment (such as annealing) to relieve stresses and improve mechanical properties, followed by surface finishing (like pickling or grinding) to remove oxides and enhance corrosion resistance.
To determine if Hastelloy C276 forgings meet your needs, assess their chemical composition, mechanical properties, and resistance to corrosion under the specific conditions of your application. Conduct testing such as tensile, impact, and corrosion tests for confirmation.
The ideal temperature range for forging Hastelloy C276 is between 1,900°F and 2,200°F (1,038°C to 1,204°C). This ensures proper deformation without compromising material properties.
The real strength of Hastelloy C276 forgings is seen in action within some of the world’s most challenging settings. They are vital in chemical processing plants, handling aggressive acids and catalysts, and are equally at home in pollution control scrubbers and flue gas desulfurization systems. You’ll also find these forgings performing reliably in marine engineering, pulp and paper production, and industrial waste treatment, essentially anywhere corrosion resistance is non-negotiable for safety and long-term performance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
