摘要

This study presents the results of developing a production technology and evaluating the properties of rolled heavy plate made from the heat-resistant steel 10Kh2M1, a domestic analog of ASTM A387 Grade 22 Class 2 steel. A production technology for rolled plate with thicknesses ranging from 8 to 150 mm was developed and successfully implemented at the Mill 5000 of the United Metallurgical Company (OMK). A comprehensive testing program confirmed that the plate fully meets the specifications of GOST 34347–2017 Steel Welded Vessels and Apparatus. General Technical Conditions and the design requirements for materials intended for manufacturing equipment used in advanced oil refining, petrochemicals, chemicals, and mineral fertilizer production. The 10Kh2M1 steel developed matches the properties of its imported counterpart, ASTM A387 Grade 22 Class 2, and significantly exceeds its yield strength for thicknesses up to 110 mm. Technical specifications TU 24.10.35-004-40791603-2024 for 10Kh2M1 steel were developed based on this work and were approved and registered in the product catalog. This grade is classified as a fifth-generation steel due to its key characteristics, specifically the J-factor value and impact toughness. Currently, rolled plates made from 10Kh2M1 steel are used in equipment manufacturing as fully interchangeable substitutes for ASTM A387 Grade 22 Class 2.
