Abstract: Clad steel roiled section suitable for reinforcing concrete is disclosed, which is produced from a bimetallic ingot comprising a basic material containing a group of alloy elements including Si and Al, and a surface layer of a ferritic or austenitic stainless steel containing a group of alloy elements including Cr and Ni, by hot rolling the ingot to an intermediate billet and a rolled section, and subjecting the rolled section to heat treatment. A feature of the reinforcing clad steel rolled products is that the basic material is steel containing, in percent by weight, from 1.0 to 5.0 Si and from 0.1 to 5.0 Al, with the proviso that 3.0≦(Si+Al)≦6.0. The reinforcing clad rolled products exhibit superior mechanical strength and impact toughness, improved corrosion resistance and high bond strength between the layers and with concrete.
