What is Hastelloy Hollow Bars?

Typically, Hastelloy Hollow Bars are made up of nickel (up to 60%), molybdenum (15–30%), and chromium (12–23%), with small amounts of iron, tungsten, and cobalt added based on the specific grade (like C22, C276, or B2). This unique alloy blend offers exceptional resistance to pitting, stress corrosion cracking, and crevice corrosion in both oxidizing and reducing environments. Hastelloy boasts a tensile strength of around 690–785 MPa and maintains impressive mechanical stability, even at high temperatures, ensuring it performs reliably under thermal and chemical stress.
