What is C276 material?

What is C276 material?

Alloy C276 (UNS N10276) is an austenitic nickel-molybdenum- chromium alloy with a small addition of tungsten. It is one of the premier corrosion resistant materials available for process industries. Alloy C276 has excellent corrosion resistance in both oxidizing and reducing environments.

What is C276 Hastelloy?

HASTELLOY C276 is a Nickel-chromium-molybdenum wrought alloy that is considered the most versatile corrosion resistant alloy available. Alloy C-276 also has excellent resistance to pitting, stress-corrosion cracking and oxidizing atmospheres up to 1900°F.

What is Hastelloy C276 used for?

It is widely used in the heat exchangers, evaporators, transfer piping, and the reaction vessels primarily due to its ability to resist the harsh conditions prevailing in the chemical processing industries that result in stress corrosion cracking and pitting corrosion.

What is the difference between Hastelloy C22 and C276?

The major difference between Hastelloy C22 and C276 is that the Hastelloy C22 is very important due to its enhanced versatility and exceptional resistance to chloride-induced pitting whereas the Hastelloy C276 is very important due to its proven performance in a wide range of aggressive chemicals.

What is the difference between Hastelloy and Inconel?

Inconel® materials belong to a family of nickel/chromium alloys that are non-magnetic and take corrosion resistance to elevated temperatures. The Hastelloy® family of nickel/chromium/molybdenum alloys are ideal for use in highly aggressive chemical environments at elevated temperatures.

Is Hastelloy C276 stainless steel?

Hastelloy® C-276 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.

Why is Monel good for shipbuilding?

Stronger than pure nickel, Monel alloys are resistant to corrosion by many aggressive agents, including rapidly flowing seawater. Monel was created in 1905 by Robert Crooks Stanley, who at the time worked at the International Nickel Company (Inco).

Is Hastelloy C276 NACE compliant?

Hastelloy C276 is the most universally corrosion resistant material commonly available today. This material is NACE MR0175 certified for oil and gas service. It is also approved as a material for construction by the ASME Boiler and Pressure Vessel Code.

What is the UNS number for Hastelloy C276?

UNS N10276
HASTELLOY® C-276 alloy (UNS N10276) was the first wrought, nickel-chromium- molybdenum material to alleviate concerns over welding (by virtue of extremely low carbon and silicon contents).

What is C22 alloy?

Alloy C22, is a versatile austenitic nickel-chromium-molybdenumtungsten alloy with enhanced resistance to pitting, crevice corrosion and stress corrosion cracking. This nickel alloy also offers optimum resistance to environments where reducing and oxidizing conditions are encountered in process streams.

What is Inconel made of?

Composition. Inconel alloys vary widely in their compositions, but all are predominantly nickel, with chromium as the second element.

What is Inconel metal used for?

Inconel® is ideally used in the oil and gas extraction industries due to its high temperature resistance and oxidation resistant properties. The oil and gas industries need a superalloy metal, like Inconel®, that can withstand extreme environments and volatile, corrosive gasses.

What is the machinability rating of Hastelloy c276?

Machinability Ratings Nickel & cobalt base corrosion, temperature and wear-resistant alloys, such as HASTELLOY C276, are classified as moderate to difficult when machining, however, it should be emphasized that these alloys can be machined using conventional production methods at satisfactory rates.

What kind of acid is c276 resistant to?

Alloy C276 has exceptional resistance to sulfuric acid and hydrochloric acid, acid chlorides, solvents, formic and acetic acids, acetic anhydride, wet chlorine gas, hypochlorites and chlorine solutions.

Why is c276 alloy used in chemical processes?

Alloy C276 also resists formation of grain boundary precipitates in the weld heat affected zone making it useful for most chemical processes in the as-welded condition. It has excellent resistance to pitting and stress corrosion cracking.

What kind of environment does C-276 alloy have?

Alloy C-276 also has excellent resistance to pitting, stress-corrosion cracking and oxidizing atmospheres up to 1900°F. Alloy C-276 has exceptional resistance to a wide variety of chemical environments.
