Increasing the strength characteristics of the proposed alloy occurs while maintaining sufficiently good values of ductility.

The marked superiority of the strength characteristics is also observed during high temperature tests. In this case, it is necessary to emphasize the results of long-term temperature tests, showing: their increase in the operating time of the new alloy by 1.5-2.0 times in comparison with the known.

The proposed alloy can be used as a constructional material to be welded for the manufacture of products that work for a short time and for a long time at elevated temperatures.
