A5.20/A5.20M:2025 - SPECIFICATION FOR CARBON STEEL ELECTRODES FOR FLUX CORED ARC WELDING

Member Price: $66.00

Non-Member Price: $88.00

This specification prescribes the requirements for classification of carbon steel electrodes for flux cored arc welding.
The requirements include chemical composition and mechanical properties of the weld metal and certain usability characteristics.
It also includes optional supplemental designators for lower temperature toughness requirements, diffusible hydrogen limits, and shielding gas range designators. Additional requirements are included for standard sizes, marking,
manufacturing, and packaging. A guide is appended to the specification as a source of information concerning the classification system employed and the intended use of carbon steel flux cored electrodes. This specification makes use
of both U.S. Customary Units and the International System of Units (SI). Since these are not equivalent, each system must be used independently of the other.
