The paper presents the variation of mechanical characteristics of resistance
and plasticity for thin wall tubes made of stainless steel 10TiNiCr180, processed in
ultrasonic field. Decrease of mechanical characteristics of resistance and increase
of plasticity ones in tubes processing in ultrasonic field, with respect to classic
technology, are made on account of cold hardening reduction, implicitly metal-tool
contact friction. Tubes processing is made through drawing without inner
guidance/to empty, using convergent conic dies made of metallic carbides.
