STRUCTURE AND PROPERTY FORMATION FOR PIPE COILED ROLLED PRODUCT DURING MANUFACTURE UNDER CASTING AND ROLLING COMPLEX CONDITIONS

摘要

Results are provided for a comprehensive study of the structure and properties formation of micro-alloyed pipe steel produced in an AO United Metallurgical Company (Vyksa) casting and rolling complex conducted under laboratory and industrial conditions. The features of structure formation established are used to create steel compositions for electrically welded pipes and coiled rolled product manufacturing technology corresponding to steels strength classes up to K60 with improved toughness and cold resistance.
