Abstract

The importance is demonstrated of developing new low-carbon high-strength steels for a marked improvement in both mechanical and service properties of a main metal layer, strength and continuity of joined layers, and also quality characteristics of corrosion-resistant clad rolled product as a whole. In order to resolve this problem on the basis of original methods of physicochemical prediction a new low-carbon high-strength steel is created of weldable economically alloyed steel, and its main production technology is developed. It is shown that in order to achieve simultaneously high strength indices (yield strength more than 700 MPa, strength more than 850 MPa), ductility (relative elongation more than 17%), and other steel service properties, nanostructuring is of prime importance, realized with relatively slow metal cooling rates typical for preparing clad rolled product.
