Аннотация:It is established that structural inhomogeneity of 20-KSKh steel rolled product produced in the casting and rolling complex at OMK-Stal is caused by presence of bainitic areas within a ferrite-pearlite matrix. Differences in this inhomogeneity are shown due to banding of the ferrite-pearlite structure, determined according to GOST 5640. A method is proposed for evaluating the degree of structural inhomogeneity (banding number) containing bainitic areas. Comprehensive corrosion tests are performed for specimens with “bainitic” and ferrite-pearlite banding. It is established that specimens with “bainitic” banding exhibit better corrosion resistance.
