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.
