2¼Cr-1 Mo是一种主要用于高温应用的低合金铁素体钢。虽然关于2¼Cr-1 Mo锻造形式的大量数据存在，但关于2¼Cr-1 Mo焊接金属的高温性能的信息很少。由于焊接是使用2¼Cr-1 Mo的主要制造方法，因此焊接金属数据的缺乏是由2¼Cr-1 Mo制造的压力容器的设计者关注的问题。当前的研究是为了响应对更多焊接金属数据的需求而启动的。

2 ¼ Cr-1 Mo is a low-alloy ferritic steel used primarily for high temperature applications. While extensive data exists on 2 ¼ Cr-1 Mo in wrought form, scant information is available on the high temperature properties of 2 ¼ Cr-1 Mo weld metal. Since welding is the primary fabrication method used with 2 ¼ Cr-1 Mo, the paucity of weld metal data is a matter of concern to the designers of pressure vessels constructed of 2 ¼ Cr-1 Mo. The current study was initiated in response to the need for more weld metal data.
