Study on the Influence of the Chemical Composition in the Thermomechanical Processing of the Steel Products
Keywords:
microalloyed steel, heavy plates, thermomechanical treatment, controlled rolling, chemical composition, mechanical characteristics
Abstract
This paper presents the results of industrial scale researches on the influence of the chemical composition on the characteristics of high yield point plates of wieldable fine grain steels. The comparative study of the mechanical characteristics obtained by the classical process and by the controlled rolling process point out the possibility of replacing the classical heat treatment for some steel grades, for plates used metallic structures in railway bridges, high tornage travelling cranes, marine platform bases, high pressure vessels, etc.
