Abstract��The cracking causes of a portable carbon dioxide extinguisher HPb59-1 lead brass valve were analyzed by means of chemical composition analysis�� macroscopic analysis�� fracture scanning electron microscopy and energy dispersive analysis�� metallographic structure analysis�� etc. The copper valve of fire extinguisher occured stress corrosion cracking by the combined action of tensile stress and corrosive elements such as S and Cl. Some suggestions were put forward to improve the material selection�� control the stress level of the parts and reduce the effect of corrosion medium.

Key words�� Key words: copper fire extinguisher valve stress corrosion cracking
