Microstructural Condition Features of High-Strength Steels for Large Diameter Pipes

摘要

Results are given for analysis of cooling rolled plate after the last pass in a mill up to the instant of cooling to 200A degrees C. Calculations are provided for controlled cooling for four thickness of rolled plate of steel of strength class K65 (X80). Precision x-ray diffraction is used for quantitative and qualitative study of the microstructure obtained in rolled product.
