1.2379 steel
1.2379 steel, also known as D2 tool steel, is a high-carbon, high-chromium tool steel that offers exceptional wear resistance and cutting performance. This versatile material contains approximately 1.55% carbon and 12% chromium, along with additional alloying elements such as molybdenum and vanadium. The steel's unique composition results in excellent hardness, reaching up to 62 HRC after heat treatment, while maintaining dimensional stability. The material exhibits superior resistance to both abrasive and adhesive wear, making it ideal for applications requiring extended tool life. In the manufacturing industry, 1.2379 steel has become a go-to choice for cutting tools, forming dies, and industrial knives. Its high chromium content provides enhanced corrosion resistance, while the balanced carbon content ensures optimal hardness without compromising toughness. The steel's microstructure, characterized by well-distributed carbides, contributes to its exceptional wear resistance and edge-holding capabilities. This material performs exceptionally well in cold work applications, particularly in the processing of materials with hardness up to 62 HRC. The steel's thermal stability allows it to maintain its mechanical properties even under moderate temperature conditions, making it suitable for various industrial applications.
