The authors study an economically alloyed martensite-aging steel, the content of its alloying elements being: 0.06% C; 4.25% Ni; 3.90% Cr; 1.93% Mo; 0.48% V; 1.45% Mn; 0.42% Si. A decrease in thermal stresses was recorded in a rigidly fixed specimen within the gamma--alpha transformation temperature range. For the temperature ranges and alloying element contents studied, thermal stresses in the filler metal, their relaxation, and the steel's tendency to shape distortion increases when the steel is alloyed with Mn and Ni and decreases due to alloying with Si, Cr, and Mo. The alloying of filler metal with Ni and Mn ensures 2-3 times higher stress relaxation and 30-40% lower residual stress levels in comparison with the respective values for steels alloyed with Cr, Si, or Mo.
