Russia’s Magnitogorsk Iron and Steel Works (MMK) has started production of a new type of rolled steel designed for use in extremely low-temperature environments, expanding its MAGSTRONG range of high-strength and wear-resistant steels.
The new product, MAGSTRONG CRYO, is a structural cryogenic steel developed for applications at temperatures as low as -196 Celsius, typical for the storage and transportation of liquefied gases, including LNG. At such temperatures, conventional steel can lose ductility and become prone to failure, while cryogenic grades are designed to maintain toughness and resistance to fracture.
MMK said it has developed production technology to ensure required mechanical properties across a wide thickness range. The company currently offers hot-rolled MAGSTRONG CRYO products in thicknesses from 4 mm to 50 mm.
The product line includes two grades: MAGSTRONG CRYO 480, with a yield strength of 480 MPa, and MAGSTRONG CRYO 580, offering higher strength with a yield strength of 580 MPa.
The new steel is intended for use in equipment and infrastructure related to the production, storage and transportation of liquefied gases.
MMK is a major Russian steel producer operating a fully integrated production chain, from iron ore preparation and coke production to the manufacture of downstream steel products. The company has an annual crude steel production capacity of around 14.5 mln tons per annum.
