Abstract
High-strength low-alloy steels with high service properties, in particular, resistance to atmospheric corrosion, become ever wider applied in mechanical and industrial engineering. Their application allows not only reducing specific weight of metal structures, but also increasing their reliability and operating life. In view of that, on the base of steel 06g2B, steel 06g2BdP with higher corrosion resistance was developed. In order to improve its corrosion resistance, copper and phosphorus content in the steel was increased. The work deals with the issue of the impact of thermal cycles of welding on mechanical properties and structure of HAZ metal in welded joints of atmospheric-resistant steel 06g2BdP. It is shown that as to the values of static strength, ductility and impact toughness steel 06g2BdP is not inferior to steel 06g2B, and is superior to steel 10KhSNd. Its application is rational as an alternative to the above-mentioned steels in fabrication of modem metal structures by gas-shielded manual and mechanized arc welding in the range of HAZ metal cooling rates specified for them. 13 Ref., 2 Tables, 4 Figures. Keywords: corrosion-resistant steel, thermal cycle of welding, heat-affected zone, structure, properties
