Technical characteristics

Alloy 38NKD relates to steels of a precision group with a defined linear expansion thermal coefficient (TCLEx106 in a range of temperatures -60 +400°C not higher than 7,8[1/C°]).

Precision alloys are manufactured on a basis of chrome, nickel, copper, mangan, cobalt. They relate to high alloys with rare physical characteristics: magnetic, elastic, thermal and electrical. Its unique properties are caused by an accuracy of chemical composition, carefulness of manufacture, processability, and absence of residual elements. Such group of alloys is used in precision machine tool building, in a manufacture of different accurate electric units, innovational technologies.

Welding:

Type Description
limitedly weldable — welding is possible at heating to 100−120°С and last heat treating
hardly weldable — in order to obtain a qualitative welded joints, it is necessary to perform the following operations: while welding to heat it up to 200−300°C, heat treating (annealing) after welding.
weldable without stint — welding is done without further heat treating or previous heating.

Percentage composition of alloy:

By virtue of a performance values, an alloy 38NKD is widely used in a modern industry. Unique properties of a material are conditioned by its balanced composition. With an appearance of materials of a new generation, there has become a possibility to improve many technological processes and to provide a long-term, reliable work of a whole complex of equipment in a wide temperature range.
