Description
Basic electrode with special coating, suitable for the fabrication and repair of cutting tools. Suitable for horizontal welding. For optimal results, apply three layers one on top of the other. Preheat the workpiece to 600–700 °C and maintain this temperature during welding. Weld with the lowest possible current. HEAT TREATMENT: A) Harden by heating to 1180–1240 °C and quenching in oil at 450–500 °C. Preheat twice to 510–540 °C and allow to air cool for normalization. Hardness after heat treatment (A): 62–66 HRC. Softening: 25–30 HRC after heating at 820–850 °C for 2–4 hours and tempering in a furnace.
