Product description
Basic electrode, particularly designed for welding armour plates, dissimilar steels and for surfacing purposes. The weld metal consists of austenitic Cr-Ni-Mn-Mo stainless steel. It features high resistance to cracking caused by impact and high temperature and is therefore indicated for difficult to weld steels and depositing stress relaxing buffer layers on crack sensitive base metal or beneath hardfacing deposits. Use with DCEP. No pre-heat or post welding heat treatment is needed when welding armour plates. Interpass temperature should not exceed 120°C. Shall be used with shortest possible stick-out distance, at 90° angle to the work piece.
