Cold Die Steel 1.2379, also known as D2 tool steel, is a high-carbon, high-chromium alloy renowned for its exceptional wear resistance, toughness, and stability during heat treatment. Its composition, which includes approximately 12% chromium, provides excellent hardness and resistance to abrasion, making it ideal for manufacturing precision tools such as cutting dies, punches, molds, and shear blades. The steel is designed for applications where high-performance and durability are critical, particularly in cold-working environments where impact and stress are common. 1.2379 steel undergoes a meticulous hardening process, typically involving oil quenching and tempering, to enhance its mechanical properties, achieving high dimensional stability and minimal risk of distortion. It is also valued for its ability to maintain sharp edges and withstand high pressures, ensuring consistent performance over prolonged use. This material is widely employed in industries like automotive, aerospace, and tool-making, where precision and longevity are essential. Its versatility and dependability make it a preferred choice for demanding applications worldwide.
