Hastelloy C276 Flanges ASTM B564 Hastelloy Flange

Hastelloy C276 Flanges Hastelloy C276 Flanges are made up of the nickel chromium molybdenum alloy that is called hastelloy. The composition includes 50.99% nickel, 14.5% chromium, 15% molybdenum and carbon, manganese, silicon, sulfur, cobalt, iron and phosphorus in it. The Hastelloy C276 Flanges have high melting point of 1370 degrees Celsius. This high melting point allows for higher operating temperatures of the flanges. The material also has 790MPa minimum tensile strength and 355MPa minimum yield strength.

Hastelloy C276 Flanges ASTM B564 UNS N10276 Hastelloy C276 Flanges belongs to Ni-Cr-Mo family and used in industrial applications and ASTM B564 N10276 Pipe Flanges was introduced in the mid-1960s. Hastelloy Blind Flange (e.g., Asme Sb 564 N10276), and Hastelloy C276 Weld neck Flanges are also known as super-alloys. N10276 Material Flange are suitable to attaches to pipe in very corrosive environments and high temperature corrosive environments. Ni-Cr-Mo alloy C276 Hastelloy Flanges are the most versatile Hastelloy Slip on Flange works against corrosion under reducing conditions and chromium due to molybdenum.

 

Alloy C-276 Flange (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 of Hastelloy C276 flange minimizes carbide precipitation during welding to maintain resistance to intergranular attack in heat-affected zones of welded joints. Hastelloy C276 flange is used in chemical processing, pollution control, pulp and paper production, industrial and municipal waste treatment and the recovery of “sour” natural gas.

 

Applications in air pollution control include stack liners, ducts, dampers, scrubbers, stack-gas re-heaters, fans and fan housings. In chemical processing, Hastelloy C276 flange is used for components including heat exchangers, reaction vessels, evaporators and transfer piping.

    Steel Plate are often used for structural and construction applications, pressure vessels, marine and offshord equipment, and military applications. The grade, elements and parameters of a steel plate are also important in how it is used.
    Steel plates are classified by thickness: thin plate, medium plate, thick plate and extra-thick plate.
    Thin steel plates are steel plates with a thickness between 0.2-4mm produced by hot rolling or cold rolling, and thick steel plates are those with a thickness of more than 4mm
    The general name of the good board.
    Thin steel plate refers to a steel plate with a thickness of not more than 3 mm. The commonly used thin steel plate thickness is 0.5-2MM, which is divided into sheet and coil supply. Thin
    The steel plates are generally B-type steels, cold-rolled or hot-rolled steel plates with steel grades B0-B3. Requirements for thin steel plates: smooth, smooth surface, thick
    The degree of uniformity, allowing a tight iron oxide film, must not have cracks, scarring and other defects. The process is divided into hot rolled sheet steel and cold rolled sheet
    plate. Mainly used in Changlin Dongfeng fans, automobiles, electrical equipment, vehicles, agricultural machinery, containers, steel furniture, etc.
    Thick steel plates refer to steel plates with a thickness greater than millimeters. Thick steel plate is divided into extra-thick steel plate and medium-thick steel plate.
    Medium and heavy steel plates refer to steel plates with a thickness greater than 3 mm and less than 50 mm. Medium and thick steel plates are mainly used in shipbuilding, boilers, bridges
    Armor and high-pressure vessel shells, etc.
    Extra-thick steel plate refers to a steel plate with a thickness of not less than 50 mm. Extra-thick steel plates are mainly used in shipbuilding, boilers, bridges and high-pressure vessel shells
