Hastelloy C-22 Round Bars
Hastelloy C-22 round bars are solid cylindrical bars made from Hastelloy C-22, a high-performance nickel-chromium-molybdenum alloy known for its exceptional corrosion resistance. These round bars are used in various industrial applications where resistance to corrosion and high-temperature performance are critical. Here’s some information about Hastelloy C-22 round bars:
Austenitic grade Hastelloy C22 is a popular choice for applications involving industries such as Marine, Chemical processing, Waste disposal, Power, Pollution control as well as Paper processing. The Alloy C22 Square Bar proves to be highly remunerative to the chemical processing industry in particular. This is because, in chemical processing systems, the occurrence of upset conditions are fairly regular. An upset condition would mean both reducing and oxidizing conditions taking place in these process streams. These upset conditions could cause stress to the more conventionally used stainless steel or carbon steel grade, which is why the aforementioned grades are to be avoided in process streams.

Differences between Monel and Hastelloy
Monel and Hastelloy are two different types of nickel-copper alloys. Monel is more corrosion resistant, but it is less heat-conductive. It also has a lower melting point. This makes it perfect for high-temperature uses such as stove tops and gas pipes. But if you want a material with a higher melting point, you would be better off choosing Hastelloy because it can withstand very high temperatures without losing any strength or corrosion resistance. Monel is a nickel-copper alloy that resists corrosion in acidic environments. It can be used in piping, valves, and other fluid transfer components.
Monel parts are also good for use in high-temperature applications. Hastelloy is an alloy of nickel, chromium, and molybdenum. It provides the right mix of both tensile strength and corrosion resistance for most industrial applications. Monel is a family of iron-nickel alloys containing nickel and copper, called cupronickel. Monel metal is nonmagnetic and resistant to corrosion in seawater. Hastelloy is a family of nickel-based superalloys, with a percentage of cobalt, titanium, iron, and molybdenum making up the composition. Hastelloy has a much higher nickel content than Monel. Monel is a nickel-copper alloy, and Hastelloy is a series of alloys containing nickel and several other metals. Monel has a low voltage coefficient and is resistant to most corrosive environments. Whereas Hastelloy is designed for applications in high-temperature, oxidizing environments.
Differences between Inconel and Hastelloy
Inconel and Hastelloy are both nickel-chromium-molybdenum-based alloys. They are all corrosion-resistant and extremely strong metals. Hastelloy has greater molybdenum content than Inconel, although Inconel has a higher chromium concentration. This sets them apart in terms of corrosion resistance in different situations.
