Welding grade 91

06 February 2019

In their article, ‘Welding Grade 91 with dissimilar metals’, Paul Murphy from Masteel U.K. Ltd, and Dr. Sarinova Simandjuntak from the University of Portsmouth, U.K., talk about a project that originally started in late 2013 that examined the integrity of welding grade 91, which is a high chromium alloy steel, to stainless steel grades 304 and 316.

“G91 is a commonly used material in high temperature power plants due to its high temperature creep resistance,” Murphy and Simandjuntak explain. “Tungsten inert gas (TIG) welding was used to ensure a high quality weld with minimal defects and inclusions.”
