Improvement of Chemical Composition and Production Regimes for Manufacture of K65–K70 (X80–X90) Strip Based on Simulation

The effect of deformation temperature scheme in the finish rolling stage and cooling regime on structural component morphology and set of strength properties for pipe steel is demonstrated. Improved chemical composition and production regimes are established on the basis of quantitative correlations for structure and properties of pipe steel using a Gleeble simulation system. Results are presented for manufacture of industrial test batches of...
