Danish mill Dansteel expands range of structural steel plates: NLMK

Danish plate mill Dansteel, part of Russian mining and steel group NLMK, has expanded its range of weather-resistant steel plates for bridge construction, with 30% stronger grades.

NLMK said Feb. 16 that Dansteel has added 10 structural steel grades with a tensile strength of up to 460 MPa and up to 100mm thicknesses. Previously, the mill developed production of 355 MPa steel in up to 80mm thicknesses.

The new grades are on average 30% stronger than their previous counterparts and ensure high welding quality and crack resistance at low temperatures.

The engineering characteristics of the new grades, which are also tolerant to corrosion, were achieved through optimizing the steel’s chemical composition, and developing optimal plate rolling modes with accelerated cooling.
