Some common high strength steels possess enough magnetostriction to serve as the active material ... more Some common high strength steels possess enough magnetostriction to serve as the active material in sensors, e.g. torque sensors, while simultaneously performing their usual structural role. The magnetization and magnetostriction of six common high strength steels have been measured as a function of stress. Measurements were made in a hydraulic load frame at compressive stresses of 1, 50, 100, and 150 MPa with fields up to 135 kA/m (1700 Oe). With two exceptions, all of the samples displayed "normal" strain-field curves. The exceptions were Maraging 300 steel whose magnetostriction was continuing to increase with stress even at 150 MPa and an SAE 4130 steel that showed an "inverted " shape. curves of all of the samples showed some small dependencies on stress but were otherwise unremarkable. The saturation magnetostrictions (S = 1 10 6) and saturation magnetization (tesla) were: AerMet 100
