The handbook provides data on corrosion of materials in the main environments of chemical industries and oil refineries, as well as in water and some coolants. The effect of aggressive media on the mechanical properties of metallic and non-metallic materials is reflected. Brief technological characteristics, information on the composition and scope of use of more than 1000 grades of materials are given. The book serves as the key to the nine-volume series of reference manuals "Corrosion and Protection of Chemical Equipment," published by the publishing house "Chemistry" from 1969 to 1974.
