HF 30S
High efficiency electrode for hardfacing
Description & applications
Synthetic rutile coated hardfacing electrode with high recovery (160%). For applications subject to abrasive wear by minerals, combined with medium impact and compression. Austenitic matrix containing Cr carbides. The deposit resists to corrosion due to the high chromium content as well as heat up to 200°C.
Easy flow, smooth bead surface, self releasing slag. Surfacing in 1 - 2 or eventual 3 layers for all pieces subject to high abrasion combined with a good resistance to shocks. Only machining by grinding.
General applications: For excavating and crashing equipment, surfacing of endless screws, mixer blades, pump bodies for abrasive materials, excavator teeth, crashing installations for minerals, concrete pumps, ores crushing, ploughshares, lumps break, screw presses for bricks.
