Plastic Mould Steel 1.2738 HH is a high-quality, pre-hardened steel widely used in the production of injection molds, particularly when high-performance and durability are required. Known for its excellent hardness, typically ranging from 52-56 HRC, 1.2738 HH provides exceptional wear resistance, which is crucial for maintaining mold integrity during extended production cycles. Its high toughness and strength ensure that molds can withstand the mechanical stresses associated with injection molding processes, reducing the risk of cracking or chipping. This steel also offers superior machinability, enabling precise mold fabrication with high-quality surface finishes. Additionally, the steel's resistance to corrosion and oxidation is advantageous for molds exposed to aggressive or moisture-sensitive plastics, extending the lifespan of the tooling. Plastic Mould Steel 1.2738 HH is commonly used in a variety of industries, including automotive, electronics, and consumer goods, for molding intricate, high-precision parts. Its pre-hardened condition allows for quicker turnaround times and fewer heat treatments, making it a cost-effective choice for many mold-making applications.
