摘要

X2 0CrMoV1 2 1钢是按德国DIN1 71 75标准生产的耐热钢

其最高使用温度为 6 5 0℃

在进口火电高温高压机组中应用较多。由于其合金含量较多

焊接性能很差。电站建设中

一般都将其作为焊接工程的难点和重点。介绍了X2 0CrMoV1 2 1在四川某电站工程中的具体应用

并对其焊接性能进行了分折

详细介绍了所采取的焊接及热处理工艺措施

Abstract

X20CrMoV121 steel is the heat-resistant steel produced in accordance with DIN17175

the Germany industry standard. The highest available temperature is 650℃ and it is applied mostly in the high-temperature and high-pressure imported units. It has been regarded as the important and difficult point in the power station building because of its high alloy content and poor welding property. The actual application of X20CrMoV121 steel in one power station engineering in Sichuan has been introduced

in which its welding property has been analyzed

and the measures of welding and heat treatment technology have been introduced in detail.
