[Current]Welding consumables — Covered electrodes for manual metal arc welding of creep-resisting steels — Classification
AS/NZS 4856:2022 identically adopts ISO 3580:2017, which specifies requirements for the classification of covered electrodes, based on the all-weld metal in the heat-treated condition, for manual metal arc welding of ferritic and martensitic creep-resisting and low alloy elevated temperature steels.
