We tried to investigate the damage of high-heat-load components (HHLC) for SPring-8 front ends, which had been operating for about 5 years. In case of the absorber and the XY-slit, utilizing the inclined-incidence technology with the advanced material of GlidCop, the change of the mechanical property of GlidCop and the damage of welded joints, where the maximum equivalent tensile stress appeared, were examined. Although any remarkable damage was not observed, a change of the elongation was detected along the irradiated body of the absorber. As for the pre-slit, utilizing the volumetric heating technology with a low-Z material, it was confirmed by a heating test that the soundness of the brazed joint between the low-Z material and a cooling holder was maintained.
