Thick basic-covered electrode for producing highly wear resisting hard facing deposits. It is particularly resistant to metal-to-metal wear, impact and shock. Weld metal can be machined only by using sintered hard metal tipped tools. A tough buffer layer using UNIVERS or CITOCHROMAX electrodes is solely required in case of very crack sensitive base metal. Even a large number of layers can be deposited without the need of intermediate buffer layers. CITODUR 400 B can be welded in all positions, except vertical-down. Suitable for reconditioning of rails, rail crossings and switch points, wearing parts such as dredger parts, polygon edges, bearing surfaces, striking tools, die tyres, wheel flanges, slide surfaces subject to heavy wear, reconditioning of lower dies, punches and others. Preferred to use with DC, electrode in positive (+) pole and also possible to use with AC.
