Influence of Climate-Range Temperature on Magnetic Properties of Steels of Various Composition

Resumo

It has been experimentally established that a change in the temperature of samples made of steels widely used in engineering in the range of –10 to +40°C leads to a considerable change in the magnetic properties of these steels. With increasing temperature, the area of the hysteresis loop increases. The coercive force and remanence increase with the saturation magnetization value remaining practically constant. The value of maximum magnetic susceptibility also grows. The greatest change in properties is observed in steel 10 880, which is close in composition to technical ferrum. The established changes in the magnetic properties should be taken into account when conducting magnetic testing under climatic (natural) conditions.
