哈氏C-2000合金是哈氏家族“C”合金成员,是美国Haynes国际公司本世纪创新之作,属于Ni-Cr-Mo合金,UNS编号为:N06200。该材料在国内应用案例较少,通过研究、分析该材料的焊接性,选择SMAW(焊条电弧焊)的焊接方法,按NB/T47014进行焊接工艺评定,制定合理的焊接工艺及措施,对保证焊接质量,满足设备使用要求,推广该材料在压力容器上的应用具有一定的指导作用。
Hastelloy C-2000 alloy is a member of Hastelloy family of “C ” alloys. It is an innovation made by Haynes International Inc. of the United States this century and belongs to Ni-Cr-Mo alloy with UNS code: N06200. This material has few application cases in China. Through the research and analysis of the material’s weldability, the welding method of SMAW (Electrode Arc Welding) is selected, the welding process is evaluated according to NB / T47014, the reasonable welding process and measures are formulated, Quality, to meet the equipment requirements, to promote the application of the material in the pressure vessel has a guiding role.
