WIPO Patent Application WO/2012/069035
Kind Code:
A3
Abstract:
The invention relates to an energy-storing container. The container is made of a lightweight steel having the following chemical composition (in wt%): C 0.04 - 2%; Mn 14 - 30%; Al 1.5 - 12%; Si 0.3 - 3%; Cr 0.12 - 6%, and additionally one or more of the following elements: Ti, V, Nb, B, Zr, Mo, Ni, Cu, W, Co, P, N, each at up to 5% and in total at up to 10%, wherein the remainder is Fe including common steel tramp elements, wherein the concrete alloy composition is selected in order to limit the α'-martensite fraction before or after a forming process to no more than 3%, with the stipulation that the α'-martensite equivalent according to 0.1 * wt% Mn + wt% C + 0.05 * wt% Si is between 3.4 and 10.5.
