Features and Applications
- Basic coated alloyed core wire electrode with good weldability in all positions except vertical-down
- Mainly used for surfacing on sealing faces of gaas, water and steam valves to meet stainless and wear resistant ovelays for instance.
- In the machined condition, at least a two layer build up should remain on the surface
- Preferably employed for sealing faces of gas, water and steam valves
- The weld metal features retention of hardness up to 500°C
- Scalling resistant up to 900°C
- Preheating as required by the base metal, with temperatures between 100-200°C being generally sufficient (for joining operations 250°- 400°C)
- Annealing at 650°C - 750°C may be carried out to improve the toughness values in the weld metal and in the transition zone of the base metal.
- Be careful with dilution and welding technology.
