SUPRADUR V1000 is a thick rutile coated high-efficiency MMA electrode, 160% recovery, the weld microstructure is a hypereutectic stainless chromium hard alloy. Used for hardfacing carbon steels and low alloy steels against abrasion by mineral particles and but exhibits limited resistance to impact and shock. Smooth, regular weld beads are deposited with only minimum penetration. The hardness cracks which typically appear in this weld metal are not detrimental to resistance against mineral abrasion. When welding crack sensitive base materials a buffer layer is required using 307 type MMA electrode.
- The deposit is only machinable by grinding.
- Flat welding position only.
- Shall be used in DC+ or AC current.
