General Description

AS DA-710 is a heavily coated, Ni alloyed basic electrode. It is particularly useful for the welding of fine-grained steels and low alloy steels which have high impact resistance at low temperatures down to - 60°C. It is used for the welding of joints which need to have high toughness values at low temperatures. It gives a weld metal that has an excellent corrosion resistance to sea water and to sulphuric acid fumes. It has about 120 % metal recovery.
