Abstract It is determined that the effectiveness of steel 20 anti-corrosion protection in water by cabbage head extract increases with its concentration increase. At the same time, the degree of corrosion protection reaches up to 94%, respectively, at the inhibitor concentration of 50-70 g/l. In the presence of an inhibitor, the resistance to corrosion-fatigue fracture of steel 20 increases on average by 3 - 4 times, while the nature of corrosion-fatigue fracture changes.
