摘要
通过优化熔敷金属化学成分 ,促使熔敷金属形成针状铁素体 (AF)组织 ,提高了熔敷金属的低温冲击韧性 ,研制出具有国内先进水平的THJ5 0
The weld metal could form the microstructure of acicular ferrite by optimum match of chemical composition of deposition metal, so that the low temperature impact toughness could be increased. We have developed THJ507R covered electrode with high toughness possessed domestic advanced level.
