ISO 3580:2017规定了基于热处理条件下的所有焊接金属的覆盖焊条分类要求,用于铁素体和马氏体抗蠕变和低合金高温钢的手工金属电弧焊。本文件是一份综合分类规范,使用基于全焊缝金属化学成分的系统,对全焊缝金属的屈服强度和冲击能有要求,或使用基于全焊缝金属抗拉强度和化学成分的系统。a) 带有后缀字母“a”的段落和表格仅适用于根据化学成分分类为系统的电极,并要求所有电极的屈服强度和冲击能-根据本文件焊接金属。b) 带有后缀字母“b”的段落和表格仅适用于根据本文件下所有焊接金属的抗拉强度和化学成分分类为系统的焊条。c) 没有后缀字母“A”或后缀字母“B”的段落和表格适用于根据本文件分类的所有覆盖电极。出于比较目的,一些表格包括根据两个系统分类的电极要求,将两个系统中成分和性能相似的单个电极放置在特定表格的相邻行上。在一个系统中必须使用的特定表格行中,括号中显示了另一个系统中类似电极的符号。通过对特定电极的配方进行适当限制,通常(但并非总是)可以生产可在两个系统中分类的电极,在这种情况下,电极和/或其包装可在其中一个或两个系统中标记分类。
ISO 3580:2017 specifies requirements for 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.This document is a combined specification for classification utilizing a system based upon the chemical composition of the all-weld metal, with requirements for the yield strength and impact energy of the all-weld metal, or utilizing a system based upon the tensile strength and the chemical composition of the all-weld metal.a) Paragraphs and tables which carry the suffix letter "A" are applicable only to electrodes classified to the system based upon chemical composition, with requirements for the yield strength and impact energy of the all-weld metal under this document.b) Paragraphs and tables which carry the suffix letter "B" are applicable only to electrodes classified to the system based upon the tensile strength and the chemical composition of all-weld metal under this document.c) Paragraphs and tables which do not have either the suffix letter "A" or the suffix letter "B" are applicable to all covered electrodes classified under this document.For comparison purposes, some tables include requirements for electrodes classified according to both systems, placing individual electrodes from the two systems, which are similar in composition and properties, on adjacent lines in the particular table. In a particular line of the table that is mandatory in one system, the symbol for the similar electrode from the other system is indicated in parentheses. By appropriate restriction of the formulation of a particular electrode, it is often, but not always, possible to produce an electrode that can be classified in both systems, in which case the electrode, and/or its packaging, can be marked with the classification in either or both systems.
