Ductility of Hastelloy C276
Thread Content
I heard that when C276 is used to manufacture valve bellows, one technical challenge is that the harder this material becomes the more it is processed; as a result, it is difficult to work with. It is said that China has not yet mastered this technology. I would like to ask whether the statement that \"the material becomes harder as it is more processed\" refers to the poor ductility of C276 Thank you all!
We have used a lot of C276 bellows, both domestic and imported. Who says domestic products can’t be made?
C276 has a fairly high degree of ductility, but due to its high mo content, around 16%, processing is somewhat affected. The thickness of the bellows is generally between 0.5 and 3.0 mm; if difficult machining occurs, intermediate annealing can be considered. Then comes secondary processing; several companies in China have successfully processed this type of bellows, and case studies are available upon private message.
The HA-C 276 bellows are quite common. .
Hello! Why does a high Mo content have an impact on processing? Thank you!
All can be processed: valves, pipes, and pipe fittings
