Rutile flux-cored wire of T 18 8 Mn P / E307LT1 type for welding and cladding in all positions. One of the most universal alloys and for some applications a cost-efficient alternative to E312 or E309L. For tough buffer and intermediate layers for cladding of rails and switches, valve seats and in hydropower plants. Good resistance to embrittlement when operating at service temperatures from –100°C up to 650°C. The fast freezing slag offers excellent weldability and slag control in all positions. Easy handling and high deposition rate result in high productivity with excellent welding performance and very low spatter formation. Increased travel speeds as well as self-releasing slag with little demand for cleaning and pickling provide considerable savings in time and money. The wide arc ensures even penetration and side-wall fusion to prevent lack of fusion. The weld deposit offers high ductility, elongation and resistance to hot cracking, also after high dilution of "hard-to-weld" steels. The weld metal work hardens and offers good resistance to cavitation. The weld metal is resistant to scaling up to 850°C, but at temperatures above 500°C there is not sufficient resistance to sulfurous combustion gases. Ferrite measured with Fischer Feritescope 4 – 8 FN. For flat and horizontal welding positions (1G, 1F and 2F), FOXcore 307-T0 may be preferred.
