2 1/4Cr-1Mo铜就是10CrMo910钢,是我国高参数热力系统主蒸汽管道的常用钢种,可焊性较好,但对厚壁多层多道焊中出现微裂纹重视不够,该文简要提出了其中的主要问题,可供焊接枝术人员参考。
2 1 / 4Cr-1Mo Copper is 10CrMo910 steel, which is commonly used steel for the main steam pipe of high-parameter thermodynamic system in our country. It has good solderability. However, it does not pay enough attention to the micro-cracks in the thick- Proposed one of the main problems for welding sticks personnel reference.
