Abstrakt: Electron-beam melting reduces the gas content, harmful impurities and nonmetallic inclusions in ShKh15 steel, thus leading to a considerable improvement in its physical, mechanical, and electrochemical properties. Most marked is the improvement in the resistance of the steel to cyclic loads: its fatigue limit is increased by 33% to a level higher than that recorded for any steel of this class in the USSR and abroad. Compared with electro-slag and vacuum-arcmelted steels, the electron-beam-melted grade has higher fatigue strength, higher UTS under conditions leading to hydrogen embrittlement, and higher resistance to corrosion.
