NLMK DanSteel, NLMK Group’s Denmark site, is expanding its range of weather-resistant steel plates that are used in the production of bridge steel structures, adding ten grades with a yield strength of up to 460 MPa and a thickness of up to 100 mm to the previously mastered steel grades with a yield strength of 355 MPa and a thickness of up to 80 mm. The new grades are on average 30% stronger than their previous counterparts, ensuring high welding quality and crack resistance at low temperatures.
The high-level engineering characteristics of the new corrosion-resistant grades were achieved through optimizing the steel’s chemical composition, and developing optimal rolling modes with accelerated cooling. Certification test results have confirmed the high quality of NLMK’s thick plate.
