Abstract

PURPOSE: To enhance the salt resistane of a steel bar for a reinforcing rod of reinforced concrete by using steel contg. a specified small amount of Cu, V, W, etc.
CONSTITUTION: Steel manufactured by melting scrap steel, reduced iron, etc. in an electric furnace is adjusted to a composition contg. 0.10W0.25% C, 0.15W0.50% Si, 0.40W1.50% Mn, ≤0.05% P, ≤0.05% S, 0.20W0.50% Cu, 0.05W0.50% V and 0.03W0.20 W, and it is used as steel for a steel bar for a reinforcing rod of reinforced concrete. When sea sand is used as aggregate for concrete, such as steel bar for a reinforcing rod is not corroded by salt contained in sea sand by 0.1W0.3% even if the sand is used without removing salt by washing since the steel contains Cu, V, W, etc. as elements providing salt resistance.
