Extreme Corrosion resistance electrode with high Nickel content.
LoTherme-515 N electrode is weld-able in all positions, except vertical down. Stable arc, good slag remove-ability. The seam is finely rippled and notch-free. It gives a fully austenitic weld metal without hot cracks, not prone to embrittlement either at high or low temperatures.
LoTherme-515 N is recommended for cold-tough steels up to 9% Ni and working temperatures down to minus 196°C, particularly where the welded joint has to undergo hot deformation or stress relieving. Cold tough austenitic Cr - Ni steels can also be welded with LoTherme-515 N. This electrode is also suitable for joining different materials, such as austenitic to ferritic stainless steel, steels to Nickel alloys and steels to Copper alloys.
ULTIMATE TENSILE STRENGTH : 63 Kgf/mm2
ELONGATION (L=4d) : 35 %
CVN IMPACT STRENGTH (@RT) : 85 Joules
-------"----- (at Minus 196°C) : 55 Joules
Ensure that the electrodes are dry. In case of moisture pick-up, dry the electrodes at 250°C for 2 hours before use. Clean the weld area free of rust, oil, grease, paint, or any other surface contamination. To ensure minimal heat input, use short arc and stringer bead technique.
