Description: J707RH is a high toughness ultra-low hydrogen electrode with low hydrogen sodium coating. Use DCEP (direct current electrode positive) and can be welded in all positions.The welding process performance is good. The cold bending, crack resistance and explosion resistance of welded joints are good. Deposited metal has great plasticity and toughness. Application: It is used for the welding of hull structures, and is also suitable for the welding of important structures of Rp0.2≥590MPa high-strength steel.
