MECHANICAL PROPERTIES (RANGE)
• Penstock, earth moving equipments and heavy steel Fabrications made from high tensile steel.
• For welding USS -T1 steel, WEL -TEN 80 steels, SA 517 grade F and their equivalents. Specially recommended for welding ASTM AS17 Gr F Q&T steel.
• Excellent for welding fully killed fine grained steels.
Use short arc length. Weaving of electrodes, if necessary should be done at slow speed and keeping a short arc. The electrodes should be used in perfectly dry condition. The electrodes should be dried at 400° C for 1 hour to obtain better result. Maintain interpass temperature below 120° C.
