Russia’s leading steelmaker Magnitogorsk Iron & Steel Works has introduced new methods of producing cold- and hot-rolled sheets for the automotive industry as part of an inter-industry program to support domestic automakers. MMK produced hot-rolled steel for the manufacture of “cold-roll” springs that offer a substitute for imported analogues and help localize the full cycle of spring production in Russia. The Company has already delivered a pilot batch of rolled products to customers and received confirmation of their compliance with standard technical requirements. MMK specialists have also developed a method for producing round steel from special alloy steels with a guaranteed cold upset group of 66 and 66T for the manufacture of high-strength fasteners and other products using the cold forging method. In addition, during 2021-22, MMK produced three new grades of round bars that have since been sent to MMK-METIZ, the Group’s metal ware and calibration unit, for trial processing. The test results of the hot-rolled steel and fasteners made from these grades, as well as samples of fasteners from these grades with the best variants for testing, will be sent to the leading Russian truck and vehicle manufacturer PJSC Kamaz, which will conduct fatigue tests on the fastener samples and determine the best bolt design option for further use. Another area of MMK’s activity is the development of steels and their production technology for various types of agricultural machinery. As part of its MAGSTRONG range of high-strength steels, MMK currently produces two types of steels that are used in the production of agricultural machinery: MAGSTRONG AGRO 22 (analogue of 22MnB5 steel) and MAGSTRONG AGRO 33 (analogue of 33MnB5 steel). Among other program areas, MMK has singled out the production of cold-rolled and hot-dip galvanized sheet steel from dual-phase (DP) steels of different strength categories, as well as the production of cold-rolled sheet steel from ferritic and multi-phase steels. In addition, MMK continues to develop the production of wear-resistant steel sheets with yield strengths of up to 1000 MPa and extra-strength steels (1200 MPa), which help to improve the reliability of the vehicle in operation. Since 2020, MMK has been accepting orders for the production of automotive steel using cassette technology. This cold-rolling technology makes it possible to produce different types and strength classes of steel with the same chemical composition by varying the strip tension in the unit, enabling MMK to fulfill even small orders.
