Description
Hastelloy C276 plate, a high-performance nickel-molybdenum-chromium alloy commonly known as UNS N10276, is renowned for its exceptional resistance to strong oxidizing and reducing agents, as well as localized corrosion such as pitting and crevice corrosion. With a molybdenum content of 15-17% and a chromium content of 14.5-16.5%, it outperforms other corrosion-resistant alloys in aggressive environments such as wet chlorine, hypochlorite, and nitric acid mixtures.
Its excellent weldability ensures structural integrity even after fabrication. For example, Hastelloy C276 can outlast stainless steel in flue gas scrubbers or chemical reactors, significantly reducing maintenance costs. Available in thicknesses up to 50 mm and compliant with standards such as ASTM B575, it is a reliable choice for critical applications in chemical processing, pollution control, and the marine industry.
Our Hastelloy C276 plate offers a wide range of sizes and exceptional processing consistency, ensuring the long-term reliability and safety of your critical equipment in the harshest environments, significantly reducing maintenance costs and the risk of downtime.
