The corrosion process of steel St. 3 in water with the addition of sodium pyruvate has been studied by gravimetric, electrochemical methods, and the X-ray phase analysis. It is shown that the introduction of the investigated additive into the corrosive medium significantly reduces the corrosion of steel. Depending on the test time and inhibitor concentration, the corrosion rate decreases up to 3.8–6.0 times with the degree of protection of 73.9–83.3%.

Keywords: corrosion of steel St.3, inhibitor of corrosion, sodium pyruvate, covering protective layers.
