Electrodes for Creep Resisting Steels

MOLYTHERME (SPL)

AWS: SFA 5.5 E9018-D1 IS: 1395 E63BD126 EN ISO CODE: 18275-B E 62 18-3M3 P H5

Extra low hydrogen type electrodes depositing a high strength weld metal. The electrode possesses excellent operating characteristics and is suitable for welding in all positions. Weld metal has got good toughness even at subzero temperatures. Deposition efficiency is about 115%. The weld metal possesses high strength together with good notch toughness even at subzero temperatures down to minus o 50 C. Ideally suited for welding fine-grained steels, high strength steels, IS: 8500- 91, Gr 540B, 570B, 590B, IS: 2002-92 Gr.3, IS: 1875-92 class 3A or similar.

Precaution

1. During welding keep the heat input to a minimum.

2. Ensure the electrodes are dry. Re-dry the electrode at 300°C for one hour.
