The practical application of dephosphorization is discussed in the paper. Using the method of austenitic manganese steel waste re-melting, we get inevitable, phosphorus contents that exceed the admissible limits. The phosphorus increases the hardness and tensile strength of steel and it seriously affects the ductility and resistance to shock or impact. Experiments on the dephosphorization of highly allied manganese steel containing high phosphorous was made in laboratory conditions and the experimental results showed that the content of phosphorous in the steel can be lowered quickly and considerably. The industrial conditions allowed us to obtain similar results with those obtained in the laboratory. The only difference between the two experiments is the dephosphorization level, which was higher in the laboratory compared to the level obtain on an industrial scale, even if the experiments were done in similar conditions.
