Welding electrodes Monolith M-310

AWS A5.4: E310-15

EN ISO 3581-А- E 25 20 B 2 2

are used in all spatial positions except for vertical down one, with direct current of reversed polarity (“+” on the electrode)

Special properties

high heat resistance characteristics at temperatures up to +1200°С
deposition rate factor: 13,0 – 13,5 g/А·min
consumption of electrodes per 1 kg of deposited metal: 1,3 – 1,5kg.

Basic coated electrode with alloyed core rod, designed for welding of highly loaded products made of heat resistant rolled, forged and cast steels like 25 % Cr - 20 Ni %, such as 20Х23Н18, AISI 310S, W.Nr 1.4841 and their analogues, which operate in oxidized and stainless environment. They are used for installations for annealing and reinforcement, in manufacturing of steam generators, unrefined oil treatment equipment and chemical industry. Scaling resistance is kept at temperature up to +1200°C. Ferrite content in deposited metal of initial state after welding is 0 % (0 FN).
