Test and Analysis on Peeling and Cracking on Surface of 45 Steel Shafts
Abstract
Aiming at the peeling and cracking appear on the surface of a 45 steel shaft after surface quenching and grinding, we’ve conducted chemical composition analysis, hardness test and metallographic microstructure analysis for the cracked shaft sample. The results shows that the main reason for the peeling and cracking of 45 steel shafts is the stress generated due to the uneven structures produced on the surface during quenching and tempering after forging and surface quenching.
