This specification prescribes the requirements for classification of low-alloy steel electrodes for flux cored arc welding.The requirements include chemical composition and mechanical properties of the weld metal and certain usabilitycharacteristics. Optional, supplemental designators are also included for improved toughness and diffusible hydrogen.Additional requirements are included for standard sizes, marking, manufacturing, and packaging. A guide is appended tothe specification as a source of information concerning the classification system employed and the intended use of lowalloysteel flux cored electrodes.
This specification makes use of both U.S. Customary Units and the International System of Units (SI). Since these arenot equivalent, each system must be used independently of the other.
