摘要：

For manufacturing HC340LA cold-rolled steel annealed in bell-type furnaces from two melt steel of different compositions using Nb or Ti microalloying, metal samples were studied from nine experimental batches of hot-rolled semi-finished stocks. Based on the results, the efficiency of the developed principles for improving the existing technology to enhance the properties and quality of steel is substantiated while reducing production costs.
