• Suitable for highly wear-resistant hardfacing on parts subject to severe abrasive wear when exposed to medium impact stress, e.g. screw conveyors, rub rails, excavator teeth, mixer blades, sand sludge pumps, crusher jaw surface layers. • Welding properties: excellent welding properties and very good slag removal. In most cases, the uniform and finely scaled seam surface does not require reworking by grinding. Hardness of the pure weld metal approx. 60 HRC First layer on steel with C = 0.15% approx. 55 HRC First layer on Mn steel approx. 52 HRC • Welding instructions: rod electrode guide as steep as possible and short arc. Preheating not usually necessary. As there is a risk of cracks forming in the weld metal when applying multiple layers, buffer layers with UTP 630 are recommended. Rod electrode re-drying 2 h at 300°C • Standard: DIN 8555: E 10 UM 60 GRZ • EN 14700: EZ Fe14 AWS A5.13: ~ E FeCr A 1
