The hydrogen charging rate for the bearing B steel is 4 times faster than that for the unbearing B steel. Hydrogen atoms in bearing B steel are mostly trapped by defects (grain boundary. interface of boride, etc.). but in unbearing B steel are mostly dissolved atoms. However, hydrogen releasing rate when annealing at 220℃for unbearing B steel is about 3 times faster than bearing B steel. After annealing at 220℃.the peak of hydrogen in bearing B steel has been moved towards the surface by 25 nm. but in unbearing B steel the movement of the peak is about 50-90 nm. These results indicate that trace B in the steel can retard hydrogen atoms from diffusing towards interface of the emalled coating and the steel.So that trace B can get rid of the busting of the coating during or after the baking process.
