A2 vs D2 tool steel round bars?

High-carbon, high-chromium tool steels A2 and D2 are both known for their outstanding wear resistance and hardness. But the two differ substantially in important ways. Air-hardening tool steel with a low chromium content (5-7%) and a high degree of toughness is known as A2. For tools like punches, dies, and shear blades that need to balance hardness and wear resistance, it is frequently utilised. A high-chromium, high-carbon tool steel called D2 steel, on the other hand, is acknowledged for its remarkable wear resistance and hardness. It is relatively weakly tough and contains 11–13% chromium. Cold work punches and dies are only a couple examples of tooling that frequently uses it and demands a high level of wear resistance. Hence, A2 steel is a good choice for tooling that requires a balance of wear resistance and toughness, while D2 steel is a better option for tooling that requires a high degree of wear resistance.

What are the properties of aisi d2 tool steel round bars?

AISI D2 tool steel round bar is a high-carbon, high-chromium alloy steel known for its exceptional wear resistance and hardness. Some of its key properties include a Rockwell hardness of 60-62 HRC, and excellent wear resistance due to its high chromium content, which forms a hard, abrasion-resistant surface. Yet, it has relatively low toughness which makes it more brittle than other tool steels. AISI D2 tool steel has good corrosion resistance, but it is not as corrosion-resistant as stainless steel. Moreover, it has excellent edge retention, making it ideal for cutting tools and other applications that require a sharp edge. Usually, it is hardened by oil quenching and air cooling, which results in a Rockwell hardness of 60-62 HRC. It is rather difficult to grind, due to its high hardenability and high wear resistance.

What is the manufacturing process of d2 hot rolled alloy steel round bar?

The manufacturing process of the D2 hot rolled alloy steel round bar begins with the selection of high-quality raw materials. The steel is then melted in an electric arc furnace and is poured into a continuous casting machine to form ingots. The ingots are then heated and rolled into blooms, billets or slabs. After that, the slabs are reheated and hot rolled into D2 hot-rolled alloy steel round bars using a series of rolling mills. The final product is cooled and then inspected for quality and consistency. The D2 steel is typically heat-treated to achieve its final hardness and other mechanical properties, which is typically done by oil quenching and air cooling, resulting in a Rockwell hardness of 60-62 HRC. This process is also called as hot working process.
