Overview

 

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 is a nickel-molybdenum-chromium superalloy with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments. The high nickel and molybdenum contents make the nickel steel alloy especially resistant to pitting and crevice corrosion in reducing environments while chromium conveys resistance to oxidizing media. The low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance in as-welded structures. This nickel alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process application in an as welded condition.

Although there are several variations of the Hastelloy nickel alloy, Hastelloy C-276 is by far the most widely used. It's widely used in the most severe environments such as chemical processing, pollution control, pulp and paper production, industrial and municipal waste treatment, and recovery of sour natural gas.

 

Hastelloy C276 Flanges can also come in different pressure classes. The pressure classes range from 150 through 2500 or PN6 through PN64. There are different application types such as offshore oil drilling, power generation, petrochemicals, gas processing, specialty chemicals and others which use these flanges. There are special flanges like the Hastelloy Alloy C276 Blind Flanges which are used to close a pipeline either temporarily or permanently. The type of flange and the application requirements vary. The flanges are also used in pharmaceuticals, petrochemicals, sea water equipment, heat exchangers and condensers. The ASME SB564 Alloy C276 Plate flange is another type of flange used in these industries. Please contact us for more information on these flanges and their prices.
