China 825 Nickel Alloy Tubing

The China 825 Nickel Alloy Tubing provides resistance to chloride-ion stress corrosion cracking. The nickel, in conjunction with the molybdenum and copper, also gives China 825 Nickel Alloy Tubing great resistance to reducing environments, like those containing sulfuric and phosphoric acids. Aiding resistance to pit and crevice corrosion is one of the chief benefits of the molybdenum. Resistance to a variety of oxidizing substances such as nitric acid, nitrates, and oxidizing salts comes from the chromium content. Titanium, often with heat treatment, serves to stabilize the alloy against sensitization to intergranular corrosion.

The China 825 Nickel Alloy Tubing has excellent corrosion resistance. This alloy tubing offers exceptional resistance to corrosion by sulfuric and phosphoric acids and is often the most cost-effective alloy pipe in sulfuric acid service. The possession of this resistance to both general and localized corrosion under diverse conditions is what allows this China 825 Nickel Alloy Tubing to have broad usefulness and a wide range of applications. The China 825 Nickel Alloy Tubing applications include the handling of radioactive wastes, nuclear fuel reprocessing, pickling operations, acid production, oil and gas recovery, pollution control, and chemical processing.
