    Notes: Conclusions 1. Steel ÉP817 quenched from 1000° (1 h)+cold treatment at−70° for 2 h+aging at 510° for 3 h has a better combination of physical and mechanical properties than steel VNS-2 quenched from 1000° (1 h) and aged at 410–450° for 3 h. 2. Heating in the range of 400–450° induces, along with aging, destabilization of retained austenite, which is accompanied by local stresses. This has a substantial effect on the technological and operational reliability of the steel.

    Notes: Conclusions 1. To maintain the high design strength of VNS-2 and ÉP817 steels it is necessary to provide stability in their properties and gas absorption and also a uniform original structure, i. e., to accomplish the production operations on them with the minimum possible change in properties, using, in particular, heating for deformation and hardening in inert media and welding with the minimum power per length (electron beam or laser). 2. In the design of parts and assemblies made of maraging steels and the development of production operations for their production it is necessary to include the possibility of a homogenizing heat treatment of weld joints (annealing, hardening, and aging).
