Abstract��The spring washers is cracked during production. Analysis of the crack has done with SED, metallography, composition analysis and EDS etc.The result shows that it was the typical intergranular fracture,and there were scrappy claw and tiny pore in the fracture of crystal face. It is the character for fracture of hydrogen embrittlement of high yield steel. The reason for hydrogen embrittlement fracture is incomplete removal of hydrogen after acid��washing or electroplating.��
