Abstract
The mechanical and magnetic properties of 50KhGFA laminated spring steel are investigated in different regimes of the quenching and tempering temperatures. It is shown that the quality of heat treatment of this steel cannot be tested using any standard magnetic characteristic. It is proposed to test the mechanical properties of 50KhGFA steel by measuring the amplitude of pulses driven a magnetized product into the demagnetized state or using the gradient of the remanent magnetization field after pulse magnetization to saturation and remagnetization by magnetic field pulses of a constant amplitude.
