Most hydrogen in bloom isdiffusible and its room temperature diffusion coefficient is equal to about (0.85-1.02)×10~(-6)cm~2 / s. The hydrogen content in blooms after stack cooling may reduce in great extentso as to be contributed to produce the heavy rail steel free from flake at the Panzhihua Ironand Steel Company.
