H13｜1.2344｜SKD61

H13 Steel is used to manufacture forging dies, hot extrusion dies and precision forging dies with large impact load; Die casting dies for aluminum, copper and their alloys.

1.2344 steel, as a high-quality hot work die steel, has excellent comprehensive performance. It is processed by electric slag remelting to obtain a highly pure and uniformly structured material, exhibiting excellent high-temperature strength, wear resistance, and thermal fatigue resistance. 1.2344 steel can maintain stable performance in high temperature environments above 600 ℃, making it particularly suitable for harsh working conditions such as die-casting and hot forging; 1.2344 steel has good toughness and ductility, which can effectively resist impact loads. Its excellent processing performance can achieve mirror polishing effect, and its outstanding corrosion resistance makes 1.2344 steel an ideal material for manufacturing high-end die-casting molds, plastic molds, and hot work molds. It is widely used in fields such as automotive, electronics, and aerospace.

As a Japanese JIS standard hot work die steel, SKD61 steel's core highlights include excellent high-temperature performance, outstanding wear resistance and toughness, good processing performance, corrosion resistance, and wide applicability. SKD61 steel ensures material purity through vacuum degassing and electric slag remelting processes, combined with a heat treatment process of 1020-1050 ℃ quenching+550-680 ℃ triple tempering, which increases mold life by more than 50%.

H13 hot working die steel.
