| 摘 要： | 对压力容器用16MnR （HIC）钢中Mn含量对埋弧焊焊缝组织与性能的影响进行研究，结果表明，当焊缝中Mn含量在1.8~2.0之间时，焊缝金属的力学性能以及抗氢诱导裂纹性能能够满足使用要求；当焊缝中Mn含量达到2.2时，焊缝金属组织中出现了无碳贝氏体，降低了焊缝的低温韧性。

| Abstract: | In this paper, effect of manganese content on the microstructure and property of the submerged arc weld on 16MnR （ HIC） steel for pressure vessels purpose is studied. The result shows that, when the manganese content in the weld is between 1.8%and 2.0%, the mechanical properties and the resistance to hydrogen induced cracking of the weld metals can meet the requirement, and when the manganese content reaches 2.2%, carbonless bainite structure appears in the weld metal and reduces the low-temperature toughness of the weld. |
