INFLUENCE OF CHEMICAL AND MECHANICAL FACTORS ON S235 STEEL CORROSION IN ACID MEDIA

Modern technology has a wide range of construction materials available: metals, metal alloys, plastics, ceramic products, etc. Choosing the right material for the making of a given machine is a major responsibility of the specialists, a decision that can be taken only taking into account the chemical, physical and mechanical properties, but especially the effect of the interaction of the material with the environment in which it will be exploited, that is, the behavior at corrosion. S 235 steel is one of the cheapest and most widely used iron alloys. In the paper, the corrosion resistance of S 235 steel was estimated quantitatively and qualitatively, depending on different chemical and mechanical factors in HCl environment.
