当需要与08X18H10T号钢进行焊接时,为了在低合金钢的棱边上完成每一层堆焊,研制出了1种基于02X24H13焊剂(牌号为ЦЛ-25Л的焊条,Св-02X24H13焊丝)的材料。这种材料能保证熔焊金属具有较低的含碳量和规定的铁素体相含量(2%~5%)。使用这种材料焊接时能使工件获得必要的工艺性指标,且能使奥氏体-铁素体熔焊金属具有满意的工作能力:具有抗结晶裂纹生成的特性;能预防并阻止含有高硬度脆性组分的组织的形成;阻止西格玛化,从而可避免回火脆性的产生;机械性能和抗疲劳性能符合ПНАЭГ-7-002-86的要求。另外,还编制了生产焊接材料的技术文件。
When welding with 08X18H10T steel was required, a material based on 02X24H13 flux (ЦЛ-25Л, Св-02X24H13 wire) was developed for each layer of overlay on the edge of the low alloyed steel . This material ensures that the weld metal has a low carbon content and a specified ferrite phase content (2% to 5%). The use of this material when welding the workpiece to obtain the necessary technical indicators, and can make austenitic-ferritic weld metal has the ability to work: with the characteristics of anti-crystal crack generation; to prevent and prevent containing high hardness The formation of brittle components of the structure; stop the sigmaification, thereby avoiding the emergence of temper brittleness; mechanical properties and fatigue resistance in line with the requirements of ПНАЭГ-7-002-86. In addition, production of welding materials also prepared technical documents.
