DuraMax E7018 H4R is a moisture resistant, hydrogen controlled, vacuum packed, basic coated electrode which is welder friendly and is recommended for welding of mild and medium carbon steel, high strength steel, cast steel and problematic steels. The electrode is vacuum packed and hence does not require expensive redrying at 250°C for 2 hours or a higher temperature. The weld metal is clean and has lowest level of impurities thus having unique properties of resistance to ageing.
