Composition and other requirements are specified for more than forty classifications of covered stainless steel welding electrodes. These classifications include the duplex stainless steels which previously were not classified. A new designation of electrode coverings, EXXX-17, has been added. The EXXX-25 and EXXX-26 designations have been restored for electrodes intended specifically for welding only in the flat and horizontal positions. Requirements include general requirements, testing, and packaging. The Appendix provides application guidelines and other useful information about the electrodes. Safety and health issues and concerns are beyond the scope of this standard and, therefore, are not fully addressed herein.
