Abstract

Abstract:

The manufacturing process of integral special-shaped forgings of the HL-2M vacuum vessel support trunnion was introduced, and the material testing was conducted by cutting the samples from the forging body. The test results show that the yield strength of the surface and core position of the trunnion forgings are 1100MPa and 1057MPa respectively, the grain size grade of those two positions can be up to grade 4, and all mechanical performance parameters can meet the design requirements.
