Six. Product Detailed Information

1.2344 is a German brand, which is a pressure-resistant hot work mold steel. The steel after electroslag remelting is uniform in material, good in hardenability, excellent in machining performance and polishing performance, high in toughness and plasticity, good in high and low temperature wear resistance, and good in high temperature fatigue resistance and heat resistance.

The company adopts pure alloy melting, advanced alloy electroslag remelting, large-scale three-dimensional isotropic forging and unique heat treatment process. The company's sales network covers dozens of countries and regions in Europe, North America, and Asia. In recent years, it has become the exclusive mold-casting mold material supplier for many large-scale Mold-casting mold manufacturers in Germany. World-renowned companies such as Volkswagen, Mercedes-Benz and BMW all directly purchase mold-casting mold materials from CapitaLand.
