Abstract
Results of analysis of properties and weldability of sparsely-alloyed high-strength steels of 06G2B and 09G2SYuch (y ≥ 440 MPa) are given. Prospects of their use in manufacture of unique and reliable engineering structures of different purpose (bridges, towers, pressure vessels, tanks) are estimated.
Keywords: high-strength steels, weldability, strength properties, cold resistance, delayed fracture
