Abstract: A non-oriented electrical steel strip or sheet having the following composition, in percent by weight: 3.2 to 3.4 of Si, 0.85 to 1.1 of Al, 0.07 to 0.18 of Mn, 0.01 to 0.04 of P, 0.0003 to 0.0030 of S, 0.0005 to 0.0020 of N, 0.0010 to 0.0050 of C, 0.0015 to 0.0040 of Ti, 0.01 to 0.008 of Cr, up to 0.05 in total of Nb+Mo+V, balance Fe and unavoidable impurities up to a total amount of 1.0% and having a specific electrical resistance at 50° C. of 0.62 to 0.65??m. Also, a process for the production thereof and the use thereof in iron cores of rotating electric machines, in particular in electric motors, for example in electric vehicles or hybrid vehicles, and generators.

Abstract: The invention relates to a non-grain-oriented flat metal product, which inter alia has comparatively high weight proportions of Mn and Cr. The invention also relates to a method of production and to a use.

Abstract: The present invention relates to a process for producing a non-oriented electrical steel strip, comprising at least the following process steps (A) provision of a hot-rolled, optionally separately heat-treated, non-oriented electrical steel strip, (B) cold rolling of the electrical steel strip from step (A) to a thickness of from 0.5 to 0.8 mm in order to obtain a first cold-rolled strip, (C) intermediate heat treatment of the first cold-rolled strip from step (B) at a temperature of from 700 to 1100° C. in order to obtain an intermediate-heat-treated, first cold-rolled strip, (D) cold rolling of the intermediate-heat-treated, first cold-rolled strip from step (C) to a thickness of from 0.24 to 0.36 mm in order to obtain a second cold-rolled strip and (E) final heat treatment of the second cold-rolled strip from step (D) at a temperature of from 900 to 1100° C. in order to obtain the non-oriented electrical steel strip, a non-oriented electrical steel strip obtained in such a way and the use thereof.

Abstract: The present invention relates to a setting retarder for compounds that set hydraulically, containing at least one at least simple adduct and/or condensate, the retarder being produced by the reaction of at least one protein hydrolysate, one pure amino acid, amino acid mixture, and/or the hydrochlorides thereof having at least one mono-, di-, oligo- and/or polycarboxylic acid which is not derived from an amino acid, and/or a carboxylic acid derivative derived therefrom, wherein the carboxylic acid is selected from a group including carboxylic acid anhydrides, carboxylic acid halogenides, and/or carboxylic acid active esters.
