Abstract
The features of the steel rod microstructure of Sv-Sv-08GNM and 08G1NMA steel grades were investigated by complex methods. The characteristic microstructure of rod under investigation mainly consists of ferrite, bainite martensite sections and a small amount of perlite. The fact stated that high perfection of the thin crystal structure of ferrite matrix is an important factor to provide wire rod with high technological plasticity in its processing into the welding wire.
Keywords
