Structural low-carbon steel subjected to uniaxial plastic tension was accurately measured for a wide range of residual strains and at different magnetization angles with respect to the stress direction. In addition to classical magnetic parameters, new quantities with better sensitivity-stability ratios were introduced on the basis of two-phase remagnetization caused by compressive residual stress.
