Brass are some of the most common copper alloys, both due to its characteristics and utility technology. Corrosion fracture after stress corrosion are the most common form of destruction of brass. This is particularly dangerous because of the lack of early, visible signal of decohesion of the material. It is therefore important to know exactly this phenomenon to design and manufacture heavy loaded industrial constructions exposed to aggressive environments, as well as minimize the danger of destroying the structure. This paper presents the results of the influence of degree of plastic deformation on the stress corrosion of brass M63 grade. Material for the study were subjected to varying degrees of deformation. Research was conducted in the corrosive sea water environment. The tests were performed based on the method of BF. Brown beam test. Analyzing the results of stress corrosion tests it was found that the greater degree of deformation cause the greater resistance to stress corrosion fracture of this material. The paper also contains a characteristic scanning surfaces investigation of exemplary samples after stress corrosion tests.
