Applications

Welding wire suitable for the welding of tool steels with high impact and shock resistance. Good resistance to softening at moderately high temperatures. This combination of properties makes it suitable for many hot and cold work applications. Bull riveters, concrete breakers (moll points), riveting dies, powder metal dies, notching dies, dowels, drills, drill plates, hubs, plastic mold dies, cold forming dies, blanking dies, bending dies etc.
