Popis:	Comparing the mechanical properties of the angle-bar steel used in the framed structures of a clamp-forming machine after long-term operation with the initial state of the steel, we discover that its strength and plasticity do not undergo significant changes but the impact toughness became lower almost independently of the sign of variable stresses. To estimate the in-service degradation of properties, we apply the electrochemical approaches and show that the polarization resistance is a quite sensitive informative parameter.
