Matching the analysis and properties of ultra-high-strength steel with weld metal from iron powder low-hydrogen type electrodes found possible. The development of ultra-high-strength steels (220@000- 300@000 psi) is reviewed and weld metal developed for use in their fabrication. Six different types of ultra-high-strength weld metal are proposed and the following properties investigated: Trans-verse and all-weld metal tensile and yield strengths@ ductility@ hardness@ transverse and longitudinal bending properties@ tough-ness as measured by the Chmpy V-notch impact@ Jominy hard-ness@ grain size determination and Lchigh restrained cracking tests. Most of the tests were made on the weld metal tempered over a wide range of temperatures.
