Abstract The contraction of the sub-section of 45 # round steel for mechanical tensile testing, spectrum analysis and sample high-powered organizational structure and the internal fracture of a comprehensive analysis that the hydrogen content within the steel is caused by too much the main reason for this phenomenon . Observe the fracture morphology of a large number of samples and found that sub-contraction of the round steel sections exist at different levels of white spots, white spots can be concluded that the main reason for this situation.
