Abstract: A flat wire or a narrow strip has a profiled cross-section and is composed of a high-strength steel having the following composition (in weight-%): C 0.2-0.9%, Mn 12-25%, Si up to 0.5%, Al 0.5-2.0%, Cr 1.8-3.5%, S max. 0.005%, P max. 0.06%, N max. 0.1%, Mo max. 1.5%, B max. 0.01%, Ni max. 2.0%, Cu max. 2.0%, Ca max. 0.015%, Nb 0.02-0.35% and/or V 0.02-0.35%, and, as the remainder, iron and unavoidable, production-related contaminants. The wire or strip is cold-rolled and/or cold-profiled from wire-form precursor material, and has improved Rp0.2, Rm, and A80 mechanical values.

Abstract: The invention relates to a ski edge profile made from steel. To further improve the sliding properties compared to the ski edge profiles which are known from the prior art, according to the invention it is proposed for the ski edge profile to consist of a steel alloy with a relatively low thermal conductivity.
