Area of application/characteristics
For wearing parts with medium hardness from wear-resistant metal in stamping, corrosive wearing. The hardness of deposited material can be increased (810 degrees -850 degrees Celsius). Can be polished after processing. Used on track body parts, mold, bottom mold and sticky tool. the center part is a compression of laser thermal processing tool steel wire; used for laser welding of alloy steel, plastic injection mold, with perfect corrosion resistance, good gloss, and and powerful performance of polishing and electrical erosion.
Instructions for welding:
process the welding area to metallic brightness, preheat it to 200-300C

The chemical composition of the pure weld deposit depends on the weld parameters applied
range of hardness: 325-375 HB
Deposited hardness of the material strongly depends on the parent material and its chemical composition. However, this influence will be decreased as welded layers increases.
