Specifies classification systems and requirements for electrodes, fluxes, and weld metal, and their chemical and physical properties. It also specifies, where appropriate, requirements for testing, packaging, marking, and storage. Guidance on the classification system and the selection of electrodes and fluxes is given in an appendix.

This Standard specifies requirements for solid and composite electrodes and fluxes for the submerged-arc welding of low and intermediate alloy steels. It defines classification systems for electrodes, fluxes, and weld metal, and specifies their chemical and physical properties. It also specifies, where appropriate, requirements for testing, packaging, marking, and storage.NOTE: The low and intermediate alloy steels covered by this Standard have alloy contents ranging up to 10.5 percent for the principal alloying metal. Higher alloy steels such as stainless steels are not included.
