1.2344 steel materials
1.2344ESR hot work die steel
Feature description
German hot work die steel, the steel is re-dissolved by electroslag, uniform material, good hardenability and good structure, excellent mechanical processing performance and polishing performance, high toughness and plasticity, good high and low temperature wear resistance, good high temperature resistance Fatigue, good heat resistance, better quality than conventional molten steel, material thickness is consistent with longitudinal and transverse strength.
Uses:
Die casting molds such as aluminum, magnesium and copper alloys. Suitable for aluminum and zinc alloy extrusion dies. Pressing tools, cold work tools. A plastic mold that requires high hardness, wear resistance, and high surface grinding.
