Abstract

The paper contains a rationale for the prospect of using high-strength structural steels in manufacturing welded structures, hoisting and transport equipment and various elements of equipment operating at low temperatures in the Far North (down to -60°C). It is shown that EN 10025-6 is a main document regulating the set of requirements for the chemical composition and mechanical properties of structural high-strength cold-resistant steels. By analyzing the regulatory documents, as well as technical specifications of large Russian and foreign manufacturers of this type of rolled products, the authors determined a set of requirements to be met by the products: high strength (Rm= 700–950 MPa, ReH ≥ 600 MPa), ductility (relative elongation А5 ≥ 14%, minimum bending radius ≥2t), as well as resistance to low temperatures (KCV-60 ≥ 34 J/cm2). It was revealed that the required set of properties for steel products with a thickness of 8 to 50 mm was achieved by steel quenching followed by high tempering, and for thicknesses of up to 10 mm by using controlled rolling and accelerated cooling.

Keywords
