What is AWS Class E91T1-B3 Flux Core Wire?

The AWS Class E91T1-B3 flux-cored wire is made up of about 2.25% chromium and 1% molybdenum, tailored for welding 2.25Cr-1Mo steels. The weld metal typically shows a tensile strength ranging from 90 to 100 ksi (620 to 690 MPa) and boasts excellent creep resistance at high temperatures. This wire is designed to work with CO₂ or mixed shielding gases, maintaining low hydrogen levels to minimize the risk of cracking. It offers smooth arc characteristics, minimal spatter, and easy slag removal. The resulting welds are tough and durable, making it perfect for code-quality fabrication and service in high-stress environments.
