1. What is a mold steel/mould steel H13(1.2344) bar/rod?
A typical hot work die steel is H13 (1.2344). In the United States, it was first made of steel. Domestically, it is 4Cr5MoSiV1. This steel has outstanding performance and is a popular hot work die steel with resistance to cold and heat fatigue. It has a high degree of toughness, good thermal strength, and red hardness. At 400–600 °C, it can be used.
It is frequently employed in light alloys like die-casting aluminum alloys, magnesium alloys, and zinc alloys and is particularly well suited for the production of extrusion dies. The main failure modes are thermal wear (melting loss) and thermal fatigue as a result of the difficult operating conditions.

The main uses of H13(1.2344) mold steel
1. Plastic mold: H13(1.2344) mold steel is frequently used in the production of plastic molds. The mold's useful life is increased by its high hardness and wear resistance, which enable it to survive the high pressure and temperature of plastics. Its cutting performance also makes it simple to process and cut, which boosts the effectiveness of mold production.
2. Die-casting mold: H13(1.2344) mold steel is frequently used in the production of die-casting molds. Due to its high hardness and heat resistance, it can withstand the high pressure and temperature die-casting process, maintaining the mold's size and shape. Additionally, during the die-casting process, its wear resistance can withstand wear and abrasive erosion.
3. Hot work mold: H13(1.2344) mold steel is frequently utilized in the production of hot work molds. It can sustain the heated working process of high temperature and high-pressure thanks to its heat resistance and thermal fatigue resistance, which keeps the mold's shape and size steady.
