SUPRADUR 600B is a thick basic coated high-efficiency MMA electrode, for depositing tough and wear resistant surfacing on components subjected to severe wear. Used for hardfacing carbon steels and low alloy steels against abrasion by minerals and medium impact and shock. Preheating to 400°C is always necessary, particularly for large work pieces and deposit a maximum of 3 layers. When welding crack sensitive base materials a buffer layer is required using 307 type MMA electrode
- Weld metal hardness ~550-650HV which can be ground. Very good resistance to moderate impacts.
- Excellent weldability in all position except Vertical Down positions.
- Shall be used in DC+ or AC current.
- All position, except vertical down
