SA738Gr. B钢焊接冷裂敏感性分析

SA738Gr. B steel welding cold crack sensitivity analysis

对SA738Gr.B钢板进行了斜Y坡口试验和插销试验,研究该钢板的焊接冷裂敏感性。试验结果表明,按照ASME II生产的核电用钢SA738Gr.B钢板具有良好的抗冷裂性能。

Oblique Y-groove cracking test and implant test was carried out on SA738 Gr. B steel plate. Welding cold crack sensitivity of this material was analyzed. The result indicated that nuclear power steel SA738 Gr. B,according to ASME II,has fine cold cracking resistance.
