General characteristics
42NKHTJU brand belongs to the group of precision alloys with high elastic properties, which are used for making sensitive elastic elements operating at t° to 100 °C. This group of alloys refers to high-alloyed alloys with rare physical characteristics: magnetic, elastic, thermal, electrical. These unique qualities are due to the precision of the chemical. composition, thoroughness manufacturing and processing, absence of impurities.

| Welding: |
|---|
| weldability limited |
— welding is possible in the process of heating up to temp. 100−120? C and further thermal treatment |
| konovalivka |
in order to obtain quality welded joints, it is necessary to perform additional operations: during welding heating up to temp. 200−300°C, heat treatment (annealing) after welding. |
| Welded without any restrictions |
— welding is carried out without further heat treatment and pre-heating. |
