Information × Registration Number 0212U006774, 0111U008105 , R & D reports Title Development of technology and manufacture of samples of hot-extruded and cold-worked seamless tubes from VT1-0 alloy billets made by electrone-beam remelting process. popup.stage_title Head Medvedev Mykhailo Ivanovich, Registration Date 09-07-2012 Organization State Scientific Research Tube Institute popup.description2 Technology of manufacture of samples of hot-extruded and cold-worked seamless tubes is developed from the billet made of allow VT1-0, got by electron-beam melting, which allows to decrease the expense coefficient of metal and reduce power inputs by reduction of amount of technological operations (exception: forging, flaying, sewing, or boring and heating before the above-mentioned operations). Executed researches of mechanical properties and structure of billet, samples of hot-extruded and cold-worked tubes proved that the developed technological parameters allowed to get the samples of hot-extruded and cold-worked seamless tubes, proper the requirements of normative document.
