D2 Steel China Price

AISI D2 tool steel is known for its high wear resistance. Compared with some other steels, it has the following characteristics:

Compared with carbon tool steels:

Superior wear resistance: Carbon tool steels such as T7-T13 have a carbon content of 0.65-1.35%. Although the quenched hardness can reach HRC60-67, their wear resistance is relatively low. The high carbon and high chromium content of AISI D2 tool steel and the addition of alloying elements enable it to form more hard carbides, which can resist wear more effectively. Under the same usage conditions, the degree of wear is significantly less than that of carbon tool steels.

Higher hardness: The tempered hardness of carbon tool steels is usually HRC60-64. After heat treatment, the hardness of AISI D2 tool steel can reach HRC55-62. While maintaining a relatively high hardness, it also has good toughness.

Compared with low-alloy tool steels:

Obvious advantage in wear resistance: Low-alloy tool steels such as 9Mn2V and CrWMn have certain wear resistance. However, the synergistic effect of high chromium (11%-13%), high carbon (1.4%-1.6%), and alloying elements such as vanadium and molybdenum in AISI D2 tool steel makes its wear resistance more prominent. In working environments with high pressure and friction, AISI D2 tool steel can better maintain good shape and dimensional stability.

Better hardenability: AISI D2 tool steel has higher hardenability. During quenching, it can obtain a deeper hardened layer, which means that it can have high hardness and wear resistance from the surface to the interior. Some low-alloy tool steels have relatively low hardenability and limited hardened layer depth, affecting their overall wear resistance performance.

Compared with high-speed tool steels:

Wear resistance has different emphases: High-speed tool steels such as M2 have very high hardness and red hardness and are suitable for working conditions such as high-speed cutting. Their wear resistance is mainly reflected in resisting the wear generated by high-speed cutting. AISI D2 tool steel exhibits excellent wear resistance in application scenarios such as cold working dies that withstand high pressure, impact, and certain friction. For example, it is widely used in cold stamping dies and cold forming rolls. However, in the field of high-speed cutting, the wear resistance advantage of AISI D2 tool steel may not be as good as that of high-speed tool steels.

Different toughness and processing properties: Compared with high-speed tool steels, AISI D2 tool steel has better toughness and processing performance. In some occasions where toughness is required and certain processing is needed, AISI D2 tool steel may have more advantages.

However, the performance characteristics of different steels will also be affected by factors such as specific manufacturers, processing technologies, and heat treatment conditions. In practical applications, it is necessary to comprehensively select the appropriate steel according to specific usage requirements and working conditions to fully exert its performance advantages.
