Repair Ability of Low-Alloyed Steel Strength of K70 (X90) Class

Abstract:

The article presents the results of studies of steel strength of K70 (X90) class. The investigated semi-finished products were graded by their repair ability (by the number of allowed repeated local heating of the material during repair). The gradation is made from the condition of the reduction of metal viscosity in the overheating zone, determined by the magnitude of the impact of Sharpy samples at the temperature of 40 °C below zero.
