• environmental cleanness of the method in combination with successful treatment;
• amplification of structure-sensitive characteristics of metal work (long-term strength, endurance, stress-corrosion cracking resistance);
• productivity to 2... 6 t/h;
• power input is an order of magnitude less than during heat treatment;
• metal does nott soften;
• metal fatigue range of welded joints is by 30% increased.

• possibility to reduce residual stresses in welded structures and directional parts from metals having a various expansion coefficient;
• scaling is excluded, and, thus, mechanical purification against scaling is unnecessary, and this prevents metal losses;
• complex use of this technology with the technology of electrohydraulic casting purification allows for combining the purification operations and residual stress relief in castings.
