Abstrakt: Considering a steel type based on the behavior pattern of an alloy's basic mechanical characteristics, a correlation has been found between the following: the characteristics of the ultimate fracture toughness of structural steels at the critical embrittlement onset temperature Tb in the compound stress state BrNFb and BrC0b and the fracture toughness in the uniaxial stress state Brb through parameters that reflect the metal state in the loading elastic–plastic range. A method for the rational selection of structural steels for products that operate under the action of nonuniform force fields of different strengths has been developed. [ABSTRACT FROM AUTHOR]
