Abstract

The structure and composition of the HPb59-1 lead-brass valve blank were expounded

and the origination of crack in the valve blank during hot stamping process was analyzed. Meanwhile

some preventive measures were presented. Based on the structure characteristics of temperature-control valve

the penetration method was determined to detect crack in the valve body samples and batch by color penetration and fluorescence penetration. The practical application shows that the color penetration exhibits desirable detecting effects
