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 hard facing against abrasion by mineral particles not resistant to impact and shock, the deposit is only machinable by grinding.
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 sensitive base materials a buffer layer deposited with SUPERCHROMAX N is required. Typical applications include hard facing subject to mineral abrasion, e.g. by sand, gravel, coal, soil, clay and related minerals used in ceramics, cement and concrete building materials and
