25Cr2Mo1V steel bolts under high temperature and pressure in the long-term mechanism of brittle


In the load, appearing first in the destruction of the grain boundary, which is used in the long process of 25Cr2MoV bolts are embrittlement and brittle fracture of the main reasons. (3) through the restoration of the internal heat can make the product particle dispersion strengthening of the role and character distortion strengthen weakened, reducing the hardness,ugg online bestellen, grain boundary have been strengthened, bolt strength was increased. Embrittlement can be eliminated to restore toughness.
