D2 Tool Steel Powder Description
D2 Tool Steel Powder is a finely ground variant of D2 tool steel, renowned for its exceptional wear resistance and hardness. This high-carbon, high-chromium, cold-work tool steel is distinguished by its robustness and high wear resistance. Commonly employed in additive manufacturing techniques such as selective laser melting (SLM) and electron beam melting (EBM), this powder facilitates the creation of complex, durable parts. It excels in producing tools used for cutting, punching, stamping, and pressing, where maintaining sharpness and durability is crucial. As a cold work tool steel powder, D2 offers an optimal blend of hardness, wear resistance, and toughness, making it an ideal choice for challenging industrial applications.

D2 Tool Steel Powder FAQs
Q1: What are the main applications of D2 tool steel powder?
D2 tool steel powder is primarily used in applications requiring high wear resistance and durability. These applications include cold pressing tooling, blanking and punching dies, coin minting dies, thread rolling dies, and surgical tools. Additionally, it is used for crafting various types of knives, such as industrial and precision knives, as well as for manufacturing precision ground shafts and pins.
Q2: What heat treatment is used for D2 tool steel powder?
To optimize its mechanical properties, D2 tool steel powder undergoes a specific heat treatment process. This includes austenitizing at temperatures ranging from 1010 to 1040°C, followed by quenching in oil or air to rapidly cool the steel. Subsequently, tempering is conducted at temperatures between 150 and 350°C. This heat treatment achieves a final hardness of 60-62 HRC, enhancing the steel's wear resistance and durability.
Q3: How does vanadium improve the properties of D2 steel?
Vanadium plays a crucial role in enhancing the properties of D2 steel. It contributes to the formation of fine carbides alongside iron and chromium, which significantly bolster the steel's wear and abrasion resistance.
