What is Hastelloy Round Bars?

Typically, Hastelloy Round Bars are made up of nickel (up to 60%), molybdenum (15–30%), and chromium (12–23%), along with trace elements such as iron, tungsten, and cobalt, depending on the specific grade (C22, C276, or B2). This unique alloy mix provides outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking. With a tensile strength ranging from about 690 to 785 MPa, Hastelloy maintains its stability even at high temperatures. Its excellent weldability, formability, and resistance to oxidation make it perfect for long-term use in aggressive chemical environments.
