Supreme Steels

D2

Product Description:

D2 is a high-carbon, high-chromium tool steel, classified as a cold-work steel, which is known for its excellent wear resistance, high hardness, and good toughness. It is commonly used in tooling applications where resistance to wear and impact is critical, such as in die-making, stamping, cutting tools, and knives. D2 has a higher carbon content than other cold-work steels, allowing it to achieve exceptional hardness and retain it at elevated temperatures.
