The Complete Guide to Hastelloy C276 Pipe
What is Hastelloy C276 Pipe
Hastelloy C276 is an alloy with special mechanical qualities made up of the metals nickel, chromium, molybdenum, and tungsten. Hastelloy C276 Pipe is renowned for its exceptional corrosion resistance in a variety of chemical conditions. Hastelloy C276 Pipe is the most well-known and widely utilized product because of its special qualities. The ASTM B622 UNS N10276 material is resistant to pitting and crevice corrosion in reducing conditions due to its high nickel content.
On the other hand, Hastelloy C276 Seamless Pipe provides resistance in oxidizing environments because to its high chromium concentration. The ASTM B622 UNS N10276 can also survive highly corrosive substances such wet chlorine gas and hypochlorite. Due to its low carbon content, Hastelloy C276 Welded Pipe helps to reduce carbide precipitation during welding. It is carried out to preserve the Alloy C276 Pipe’s as-welded structures’ corrosion resistance qualities.
Hastelloy C276 Pipe Feature
One of the most adaptable corrosion-resistant materials on the market is the wrought alloy Alloy C276 which is composed of nickel, chromium, and molybdenum. Along with having a high level of resistance to pitting and stress-corrosion cracking, it can also withstand oxidizing environments up to 1900°F, seawater, chlorides, hypochlorite, and wet chlorine gas.
In harsh conditions including chemical processing, pulp and paper manufacturing, waste treatment, municipal and industrial waste treatment, and sour natural gas recovery, it is a common choice. Additionally, it works well in closed-loop water systems and brackish water.
Hastelloy C276 Pipe’s low carbon content reduces carbide precipitation, a major welding issue with most alloy grades. This is advantageous since it maintains the as-welded structures’ corrosion resistance qualities.
ASTM B622 UNS N10276 Pipe
The American Society for Testing and Materials (ASTM) has a specification called ASTM B622 that applies to nickel and nickel-cobalt alloy pipes that are seamless. The superalloy UNS N10276, often known as Hastelloy C-276, is described in this ASTM specification.
Applications requiring strong corrosion resistance, like chemical processing, pollution control, and waste treatment, employ ASTM B622 UNS N10276 pipe. By lowering acids, salts, and chloride-containing solutions, the special proportions of molybdenum, chromium, tungsten, and nickel in UNS N10276 offer it outstanding corrosion resistance.
It’s crucial to remember that even while UNS N10276 is specified by ASTM B622, the specification only establishes the very minimum standards for the material’s chemical makeup and mechanical characteristics. Depending on the needs of a given application, additional certifications, testing, or specifications may be required.
