Chemical composition of alloy
| Mn | C | P | Cr | Si | S | Ni | Co | Cu | Mo | Cb+Ta | Fe | Al | Ti |
| 1,0 | 0,05 | 19,5−23.5 | 0,5 | ≤0,03 | 38−46 | 1.5−3.0 | 2.5−3.5 | >22 | ≤0,2 | 0,6−1.2 |
Workability
This alloy has a good workability. It can satisfactory be taken to molding. However, it is disposed to a hammer hardening. That is why it must be cut at small speeds with a special tool. It differs with an excellent weldability by dint of well-balanced composition. Welding is done without further heat treating or previous heating.
Welding
| Type | Description |
| weldable without stint | welding is done without previous heating and last annealing |
| 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, to do a heat treating (annealing) after welding |
| limitedly weldable | welding is possible at heating to 100−120°С and last heat treating |
