Description |
A heavy coated basic iron powder type low hydrogen electrode for welding of 2025 Cr - 1Mo creep resistant steels for elevated temperature service upto 600 0 C. The electrode is having very good operating characteristics like smooth and steady arc, 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 2025 Cr - 1 Mo creep resistant steel like German 10 Gr Mo 9 and 10 Cr Si Mo V7 and equivalent grades of steels for use in thermal power plants, Chemical Plants, Oil Refinery, valve manufacturing, repair of high tensile steel casting etc. |
