AWS A 5.5: E 8018 - B2 |
| Description |
A heavy coated basic iron powder type low hydrogen electrode for welding of 1 Cr - 0.5 Mo types of creep resistance steels for elevated temperature services upto 560 0 C. The electrode is having very good operating characteristics like smooth and steady arc, controlled molten slag- metal pool and easy slag detachability. The electrode can be used easily in positions. Weld deposit is of high radiographic soundness. |
| Application |
Welding of plates, sheets, pipes, and tubes of low alloy creep resistance steel like ASTM A 182- F2, F11, F12, A 387- 2, 11, 12, A 213- T2, T11, T12, A 335- P2, P11, 12 and German steels 13 Cr Mo 44, 15 Cr Mo 5 and equivalent grades for use in boilers, power plant, oil refineries, chemical plants etc. |
