PILOT PRODUCTION OF X80 ROLLED SHEET AT ALCHEVSK METALLURGICAL COMBINE

摘要

We have performed an analysis of the temperature and deformation parameters for controlled rolling/accelerated cooling on formation of the structural components inferrite-bainite microstructure and on the mechanical properties of X80 rolled sheet made from molybdenum-free steel with low values of C_e and P_(cm). Pilot production of X80 (K65) steel in thicknesses up to 20 mm with certain mechanical properties (including cold resistance) being assured was undertaken.
