Abstract

Specifies requirements for classification of covered electrodes and deposited metal in the as-welded condition and in the post-weld heat-treated condition for manual metal arc welding of non-alloy and fine grain steels with a minimum yield strength of up to 500 N/mm2 or a minimum tensile strength of up to 570 N/mm2.
