Difference Between Hastelloy C22 and C276 Tubes
What are Hastelloy C22 and C276?
The alloy Hastelloy-C22 is made up of nickel, chromium, and molybdenum. High-temperature reactors and fuel rods are made from it in nuclear power plants. In comparison to Hastelloy-C22, Hastelloy-C276 is a higher grade. Although it has a greater resistance to oxidation than C22, it still maintains ductility and malleability under stress. Although Hastelloy c22 and Hastelloy c276 are both alloy steel tubes, there are some significant distinctions between them that you should be aware of.
Difference Between Hastelloy C22 and C276
In applications where high strength is required, Hastelloy C276 Tubes, a low-alloy, medium-strength alloy, is used. It can be supplied in a round or flat shape and has a carbon concentration of up to 0.0025%. It is perfect for use in various industrial applications, such as nuclear power reactors and chemical processing facilities, due to its service temperature range of -130°C to +300°C.
A better variant of Hastelloy C22 Tubes is Hastelloy C276 because it offers more resistance to cracking than its predecessor. It is even more heat-resistant than the original material thanks to the addition of up to 0.005% carbon, but because its service temperature range is still between -130°C and +230°C, it is not as useful in high temperatures as other materials like carbon steels like austenitic stainless steel 304 or 410 which have higher melting points.
Application of Hastelloy C22 and C276
Metals like Hastelloy c22 and c276 are frequently utilized in the building of tanks, pipes, and other machinery. They are two different steel grades with various characteristics.
Because Hastelloy C22 is a high-strength alloy, it contains more nickel than typical iron-based steel does. It is mostly utilized to create armor plates and other things that must be resistant to extreme pressure or heat. Additionally, it is employed in the production of heat-resistant parts including strainers, valves, and pumps.
Temperatures of Hastelloy C22 and C276 Tubes
High-temperature nickel alloy steels come in two major varieties: Hastelloy C22 and Hastelloy C276. An alloy called Hastelloy C276 is employed in situations where high temperatures are anticipated. It is stronger at high temperatures and has a higher creep resistance than Hastelloy C22. Additionally, it is less brittle than most other alloys and stronger than brass.
When corrosion resistance is needed but high temperatures are not, Hastelloy C22 is employed. Compared to Hastelloy C276 it has less creep resistance, but at room temperature, it has more strength (about twice as much). In contrast to Hastelloy C276, which can only be forged, it is easily machined.
