Hastelloy Fitting

Product Details:

INCONEL alloy C-276 (UNS N10276/W.Nr. 2.4819) is known for its corrosion resistance in a wide range of aggressive media. The high molybdenum content imparts resistance to localized corrosion such as pitting. The low carbon minimizes carbide precipitation during welding to maintain resistance to intergranular attack in heat-affected zones of welded joints.

Alloy C-276 is a nickel-chrome-molybdenum alloy with tungsten. It is characterized by:

• Extraordinary resistance across a wide range of corrosive, watery media; in particular oxidizing and reducing acids
• Particularly high resistance against chloride-induced crevice, pitting and stress corrosion

 

Chemical Composition:
Applications:
Alloy C-276 has a broad field of application in the chemicals and petrochemicals industry, for components in organic processes containing chlorides, and for catalytic systems. The material can be used especially in cases where hot,contaminated mineral acids, solutions or organic acids. (such as formic acid and acetic acid) and sea water occur.

Examples of fields of application:

• Paper and pulp industry, e.g. for digestion and bleaching tanks.
• Washers, agitators and wet ventilators in flue gas desulfurization systems.
• Equipment and components for acid gas applications.
• Reactors for acetic acid production.
• Sulfuric acid coolers.
• Methylene diphenyl isocyanate (MDI).
• Manufacturing and processing of contaminated phosphoric acid.

Product Details:

A most versatile product like nickel-chromium-molybdenum-tungsten alloy available today with improved resistance to both localized and uniform corrosion as well as to a variety of mixed industrial chemicals but the Hastelloy C-22 alloy exhibits superior weldability and is used as weld overlay consumablesover and alloy filler wire to improve resistance to corrosion.

Hastelloy C-22 alloy has exceptional resistance to a wide variety of chemical process environments, including strong oxidizers such as cupric and ferric chlorides, chlorine, hot contaminated solutions like (inorganic and organic), acetic anhydride and acetic acids, formic, and seawater and brine solutions. Hastelloy C-22 alloy resists the formation of grain-boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in the as-welded condition.
