Classification and other requirements are specified for more than 40 grades of flux cored stainless steel electrodes and rods. New classifications include duplex alloys not previously classified and flux cored rods for gas tungsten arc welding. Designations indicate the chemical composition of the weld metal, the position of welding (newly introduced in this revision of the standard), and the external shielding medium required (for those classifications for which one is required). A special designation (K) is used to identify those classifications that are intended specifically for cryogenic service. The requirements include general requirements, testing, and packaging. The Annex provides general application guidelines for individual alloys and other useful information about welding electrodes. |
