Characteristics and typical fi elds of application Austenitic rutile fl ux-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-effi cient alternative to T 29 9 / E312 or T 23 12 L / 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 –100ºC up to 650ºC. ¡El 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. ¡El weld deposit offers high ductility, elongation and resistance to hot cracking, also after high dilution of "hard-to-weld" steels. ¡El weld metal work hardens and offers good resistance to cavitation. ¡El weld metal is resistant to scaling up to 850ºC, but at temperatures above 500ºC there is not suffi cient resistance to sulfurous combustion gases. Ferrite measured with FeritScope FMP30 2 – 7 FN. For fl at and horizontal welding positions, BÖHLER A 7-FD may be preferred.
