These specifications apply to tungsten rod with lanthanum additive for welding and cutting metals. The requirements of the technical specifications correspond to the highest category of quality.
| OKP code | Rod diameter, mm |
|---|---|
| 18 5373 4051 | 1.0 to 1.9 |
| 18 5373 4301 | 2.0 to 2.8 |
| 18 5373 4091 | 3.0 to 4.8 |
| 18 5373 4101 | 5.0 to 10.0 |
Technical requirements
Bar parameters and allowable deviations.
| Diameter, mm | Marginal deviation of the diameter, %. | Length, not less, mm |
|---|---|---|
| 1.0 to 1.9 at interval of 0.1 | ± 2,0 | 600 |
| 2.0 to 4.8 same 0.2 | ± 2,0 | 400 |
| 5.0 to 10.0 «0.5 | ± 2,0 | 150 |
- Bars with diameter 2, 8 mm and less are supplied as drawn, bars over 2,8 mm — as forged.
- Upon agreement with the customer, delivery of bars with diameter from 5 to 10 mm length no less than 70 mm is allowed.
| Component name | Mass fraction, %. |
|---|---|
| The sum of impurities: iron, aluminum, molybdenum, silicon, not more | 0,04 |
| Lanthanum oxide | 0,85 — 1,1 |
| W | basis |
1.5 The surface of the products shall be without cracks. The presence on the surface of color fading, plaque, film, oxides, burrs and traces of forging, which do not withdraw the diameter beyond the allowable deviations are not a rejecting feature.
