Hard coating electrode

AMA 1602V

DIN 8555 : E 10–UM–60R


Thick rutile-covered high-alloy electrode depositing a weld metal of hypereutectic chromium hard metal composition. It is suitable for highly wear resistant overlays subject to abrasion by mineral particles. The typical transverse cracks make such a hard weld metal not detrimental to abrasion resistance. However, the weld metal is not suitable for application where impact and shock conditions prevail. It is machinable only by grinding. On difficult-to-weld steels a buffer layer with AMA 1803J is necessary. 1602V produces extremely smooth weld beads with flat penetration. Metal recovery is approximately 160%.
