Production technology and welding properties of high heat input welding EH420 offshore steel
Extensive efforts have been made to remove “harmful” inclusions during the steelmaking process. However, the concept of “oxide metallurgy” was proposed, where fine inclusions are used to induce the formation of acicular ferrite and pin the grain boundary, thus enhancing the low temperature toughness...
