The creation of a device for salt spray corrosion tests is of great importance for the study of corrosion in the metallurgical field. Commercial salt chambers are very susceptible to maintenance repairs, thus generating a high cost. The aim of this work was to develop a low-cost device that complies with the ASTM B 117 and ISO 9227-12 technical standards. The equipment was validated by analysing its salt spray efficiency, the effects on the test specimens and calculations of the corrosion rate and mass loss. Methods were applied to build the equipment using low-cost materials that are inert to salt spray corrosion. The results obtained were analysed and compared to the technical standards, proving to be satisfactory. The visual analyses of corrosion and the calculations of mass loss and corrosion rate were similar to professional equipment, proving that the tests were valid.
