Welding Grade 91 with dissimilar metals

    Press/Media: Research

    Description

    Paul Murphy of Masteel UK and Dr. Sarinova Simandjuntak from the University ofPortsmouth, UK recently published a paper in Stainless Steel World looking at the applications of Grade 91 and the challenges of welding it with dissimilar metals.

    The integrity of welding grade 91 (high chromium alloy steel) to stainless steel grades 304 and 316 was assessed. Grade 91 is a commonly used material in high temperature power plants due to its high temperature creep resistance. Tungsten inert gas (TIG) welding was used to ensure a high quality weld with minimal defects/inclusions.
