Ural Steel developing “super steel” for the Arctic
10 December 2019
Steelworkers from Ural Steel, part of Metalloinvest, and academics from the Central Research Institute of Machine Building (TsNIIMash) are developing technology for the production of heavy plate from new unique steel grades. This plate will be suitable for building equipment designed to receive, transport and store liquefied natural gas (LNG) in arctic conditions.
The technology for producing heavy plate from these new steel grades, which contain nickel and are type 0H6, has been in development since spring 2019. During the autumn, this steel was successfully smelted at Ural Steel and a trial batch of sheets measuring 12-50mm in thickness was rolled. The production of new cryogenic steel grades will allow the Company to reinforce its position on the market for highly-profitable products.
TsNIIMash researchers are currently testing the quality of the metal, as well as the welding and performance characteristics of the trial rolled plate. The new steel grades have superior characteristics as compared to existing Russian and foreign counterparts, and also facilitate a 25% reduction in costs when manufacturing LNG equipment.
Novotroitsk’s steelworkers are experienced in developing and producing metal for cold climates. In November 2019, the collaboration between Ural Steel and the I.P. Bardin Central Research Institute of Ferrous Metallurgy won a gold medal from the organising committee at the 25th International Industry Exhibition Metal-Expo’2019. First place was awarded for the development and industrial use of strip production technology using steel of strength class X70 (K60) for the construction of a gas-collecting network at the Yamal-LNG natural gas production plant.
