The Influence of the Annealing Method on the Properties of Twice Reduced Thin Steel Sheets

Abstract

: Thin packaging steel sheet is currently used in the food industry, but it is also a frequently used material in other industries. Higher requirements for quality, reduction of energy and material intensity are the main factors that determine its development. The paper compares the test results of thin twice-reduced packaging sheets, which were produced by different annealing - continuous and batch method. Mechanical properties of these materials obtained by the uniaxial and biaxial tensile tests were compared. The anisotropic properties of thin steel sheets, which are demonstrated by the formation of ears on the cups, were evaluated by the deep-drawing cup test.
