Weldability and hot and cold working formability of Hastelloy B2 alloy
Hasteloy B2 alloy is an extremely corrosion-resistant material that is used to weld components in many demanding industrial applications. As described in **, we can see that the alloy has a unique set of processing and welding characteristics.
Welding performance
The Hasteloy B2 alloy exhibits good stability during welding, maintaining its structural integrity even in the absence of external atmosphere protection. It is not only resistant to general corrosion, but also resistant to the occurrence of stress corrosion during welding. This is essential to ensure the long-term stability of welded joints, especially in applications where post-heat treatment is not possible to relieve weld stress.

Cold working and formability
In the field of cold working, the Hasteloy B2 shows excellent formability. Despite the fast rate of cold work hardening, the alloy retains good plasticity during the forming process. This property allows for multiple repetitive deformations without intermediate annealing, which is extremely important for the manufacture of complex parts.
Thermal processing and formability
At the same time, the Hasteloy B2 also showed good performance in thermal processing. It can be formed by thermal processing over a wide range of temperatures, but it is important to note that when processing at high temperatures, the material may become more sensitive, so the processing temperature needs to be precisely controlled to avoid degradation of performance.
Conclusion
In summary, Hasteloy B2 alloy is an ideal engineering material for stability and reliability under extreme conditions due to its excellent performance in welding, cold working and hot working. Whether in the chemical, petroleum or nuclear sectors, these processing and forming characteristics of Hastaloy B2 ensure its advantages in highly corrosive environments.
