Abstract
Regularities of ageing of welded joints of steam pipelines from heat-resistant 12Kh1MF steel operating under creep conditions are considered. A connection is established between the damageability of welded joints and the carbide transformation kinetics, and recommendations are given on optimization of the initial structure of base metal.
Keywords: heat-resistant steels, welded joints, pores, life, carbides, structure, creep, steam pipelines
