Reinforced Steel

used in the preparation of reinforced-concrete structural members. The structural strength characteristics depend on the chemical composition of the steel (the percentage of carbon and alloy components) and the nature of its processing (cold hardening of the steel by drawing, stretching, or flattening, heat treatment, and so on). In the USSR hot-rolled core reinforced steel of classes A-I and A-II is prepared from carbon steel of standard designations (St. 3 and St. 5). The most widely used reinforced steel class is A-III, which is prepared from low-alloyed silicon-manganese steel (35GS and 25G2S); for highly durable reinforced steel of classes A-IV and A-V, low-alloyed steel with additives of manganese, chrome, titanium, or zirconium are used. Special heat-treated cores allow preparation of thermally hardened reinforced steel of classes A_T-IV to A_TVII. Reinforced wire is made from carbon steel of varying carbon content (0.12–0.85 percent). Requirements for the mechanical qualities of reinforced steel are set by the applicable All-Union State Standards (GOST) and by technical conditions.
