Characteristics and typical fi elds of application Austenitic rutile fl ux-cored wire of T 18 8 Mn R / E307LT0 type for welding and cladding in fl at and horizontal position. 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 –60ºC up to 650ºC. 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 wire shows good wetting behavior and results in a fi nely rippled surface pattern. The wide arc ensures even penetration and side-wall fusion to prevent lack of fusion. Used for fabrication, repair and maintenance. The weld deposit offers high ductility and elongation, 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 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 welding in vertical-up and overhead positions, BÖHLER A 7 PW-FD should be preferred.
