Hastelloy C276, designated UNS N10276, is engineered for applications requiring resistance to both oxidizing and reducing acids. Its composition offers a unique balance of nickel, chromium, molybdenum, and tungsten, providing broad-spectrum chemical resistance. This makes C276 ideal for equipment such as reactors, heat exchangers, tanks, and piping that encounter strong acids, chlorides, and mixed chemical environments.

DLX manufactures C276 plates with hot-rolling or cold-rolling techniques, ensuring uniform mechanical properties across the entire plate. Each plate undergoes stringent quality control, including chemical composition analysis, mechanical testing, and corrosion resistance assessment. The result is a product that delivers reliable performance even under severe chemical attack and high temperatures.
