CHARECTERISTICS
● For bead R overlay onto a cast iron mold which requires friction resistant.
● For repair bead R bending problem and reinforce a CAM or a Flange Dies
● Weld deposit will obtain standard hard chrome coating, no peeling off and uneven surface problems.
● Weld ability of no need underlay and after machined weld deposit will look like hard chrome coating at 90%.
● Easy to weld, beautiful weld deposit, no blowhole problems, and resulting crack resistance characteristics.
