A series of samples of various shapes, produced from spring steel 54SiCr6(CSN 14260), was prepared and annealed at 800oC at air atmosphere for 1,4,8, and 20 h. The decarburized layers that appeared on the surfaces were examined metallographically and magnetically MAT. The magnetic tests proved an appreciable sensitivity, which depended on the samples shapes, on the way of measurement and on the surface treatment of the samples before the measurement.
