俄罗斯核电用碳钢焊条УОНИИ13/55国产化替代研究

Nationalization alternative study of carbon steel electrode УОНИИ13/55 for nuclear power

通过对J507HR焊条和УОНИИ 13/55焊条实物的化学成分、力学性能的试验,以及J507HR的焊接工艺评定,结果表明,J507HR化学成分接近УОНИИ 13/55,力学性能满足核电技术要求,且部分性能优于УОНИИ 13/55,具备替代УОНИИ 13/55的条件。

J507HR electrode and УОНИИ 13/55 electrode were compared by testing and analyzing their chemical composition,mechanical properties and impact energy,and the welding procedure qualification for J507 HR electrode.The results show that the chemical compositions of J507 HR electrode is similar to that of УОНИИ 13/55 electrode,and the mechanical properties and impact energy of J507 HR electrode meet the requirements of nuclear power technology.Part of the performance indicators are better than that of УОНИИ 13/55 electrode.J507 HR electrode can replace УОНИИ 13/55 electrode for nuclear power construction.
