摘要
介绍TB/T 1979—2023《机车车辆特种金属材料耐大气腐蚀钢》的修订背景和主要修订内容。重点解析耐大气腐蚀钢钢牌号表示方法,新增钢牌号表示方法、技术要求和试验方法,以及整合修订的铁路用耐大气腐蚀钢周期浸润试验方法。针对新标准,提出相关实施建议,为新标准使用者提供参考。
In this paper,the revision background and main revision contents of TB/T 1979-2023 Special metal ma⁃terials for rolling stock-Atmospheric corrosion resisting steel are introduced.Representation method of atmospheric cor⁃rosion resisting steel grade,representation method,new specification requirements and test methods of the newly added steel grade,and integrated and test method for periodic infiltration of atmospheric corrosion resisting steel for railway are mainly interpreted.According to the new standard,suggestions are raised on the implementation of the standard,which can provide a reference for the user of the new standard.
