① Analysis shall be made for the elements for which specific values are shown in this table. If the presence of other elements is indicated in the course of this work, the amount of those elements shall be determined to ensure that their total, excluding iron, does not exceed 0.50%.
② In the designator for composite, stranded, and strip electrodes, the R shall be deleted. A designator C shall be for composite and stranded eletrodes and a designator Q shall be used for strip electrodes. For example, ERXXX designates a solid wire and EQXXX designates a strip electrode of the same general analysis, and the same UNS number. However, ECXXX designates a composite metal cored or stranded eletrode and may not have the same UNS number. Consult SAE HS-1086/ASTM DS-56, Metals and Alloys in the Unified Numbering System for the proper UNS number.
③ For special applications, electrodes and rods may be purchased with less than the specified silicon content 碳当量计算
