What is Hastelloy Round Bars?

When it comes to **Hastelloy Round Bars**, they’re primarily made of nickel, with varying amounts of molybdenum, chromium, iron, and cobalt, depending on the specific grade—like Hastelloy C-22, C-276, X, or N. These alloys are known for their outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in environments with strong acids such as hydrochloric and sulfuric acid. With tensile strengths often surpassing 690 MPa, along with excellent weldability and formability, Hastelloy round bars are perfect for creating components that need to stand the test of time and perform reliably under extreme conditions.
