Characteristics of mold steel ms1: Good thermal conductivity, high thermal strength, easy to cut, high temperature wear resistance, high toughness and high ductility. It is suitable for die-casting molds, aluminum-magnesium alloy nozzles, ejector pins and other molds with insufficient water cooling. Examples of typical applications are as follows:

1) Suitable for die-casting molds and hot forging dies that require long service life.
2) For use in light metal die-casting dies as well as light metal aluminum, zinc and heavy metal extrusion dies.
3) Used for punches and shearing tools.
4) Used in plastic molding molds. 2344 steel basic style round material flat material
