The magnetoelastic tests’ results for the 30Kh13 steel samples hardened and tempered at different temperatures are presented. The samples premagnetized to saturation are treated to a fivescore-cycle stretching effect. It is followed by repetition with the load increase by 50 MPa. The magnetic field intensity of the residual magnetization is recorded synchronously with the active load. The high structural sensitivity of magnetoelastic irreversible demagnetization = ∆H/∆σ in the low loads’ part is shown and explained. It allows using this parameter for non-destructive quality control of steels with properties close to 30Kh13 and the same composition products. Samples with a high tempering temperature of 600...700 С make it possible to create peak (limit) load sensors and fatigue damage sensors on their basis. It is proposed to use them in the form of glued foil or wire elements that can work off-line. Keywords: 30Kh13 steel, magnetoelastic memory, magnetoelastic demagnetization, magnetoelastic sliding, peak load sensor, fatigue damage sensor.
