Single Bellows

mong the many varieties of Bellows available, the most common are metal expansion joints and single metal Bellows. Materials commonly used in manufacturing Bellows include stainless steel, titanium, Monel, and high-performing alloys such as Inconel and Hastelloy. Depending on the application, Bellows can also be fabricated from bronze, aluminum, as well as copper.
Stainless steel Bellows manufactured from alloys such as 321, 304, 304L, 316, and 316L are typical. However, for higher stress applications that apply extreme temperatures or pressures on parts, the best solution is often Inconel Bellows. Bellows made of Inconel 600 or 625 not only have higher temperature and pressure tolerance, they actually harden and become stronger over time, due to the material’s unique properties.
