摘要

某高温液态金属泵用材料为316奥氏体不锈钢

其不锈钢焊条仍然依赖进口

严重制约着中国核电事业的发展。新研制的WE316HR焊条具有优良的综合性能

其熔敷金属在焊态、热处理态和老化状态下强度、冲击韧性和耐腐蚀性良好

可以用于高温液态金属泵焊接。

Abstract

Reactor coolant pump is made of 316 austenitic stainless steel. The stainless steel electrodes in reactor coolant pump are still dependent on imports

which seriously restricts the development of nuclear power business in China. The newly developed WE316HR electrode has excellent comprehensive performance. And deposited metal has good strength

impact toughness and corrosion resistance in the as-welded state

heat-treated state and aging state. It can be used for reactor coolant pump.
