• Range of Application: Applies to re-melt deposit welding process of medium-hard hot-working tools. And the temperature of working environment to make and maintain hot-working tools can reach up to 500 centigrade. For example, it’s used for die-casting dies, hot-working dies, and continuous casting roller etc. It’s also can be used for welding-repaired zinc and aluminum die-casting dies which exhibit highly heat-resistance and crack resistance.

Chemical Compositions      %

The chemical compositions of re-melt deposit materials depend on practical welding parameters.

Hardness  42-47 HRC

The hardness of re-melt deposit materials mainly depends on parent materials and its chemical compositions. But these influencing factors will decrease with the increase of welding layers.
