High carbon and high chromium tool steel grade D2 has excellent machinability and wear resistance. D2 Tool Steel Rod has the highest toughness at high hardness in sections of all sizes. FED QQ-T-570 and SAE J437 are comparable materials used in D2 Round Bars. Die-making for production lines back then utilized D2 steel.
To “punch” out large military vehicle/aircraft parts that would later be manually put together on an assembly line, D2 Tool Steel Round Bar was developed. Its properties include abrasion resistance, dimensional stability during hardening, and air hardening. Other tool steels like this are now measured against it as the tool and die standard.

What is D2 tool steel uses?
D2 Tool Steel Flat Bars are frequently used in high-wear, long-production, cold-work, and knife blade applications. It can achieve an approximate tempered hardness of between 54 and 61 HRC. Additionally, it has a roughly 275 to 319 psi range in compressive yield strength. This results in a more extraordinary hardening ability for the same.
Overall, this steel has a high tolerance to heat. As a result, D2 Steel Rods are frequently used in high-wear, high-heat applications like the manufacture of dies, tools, gauges, and shear blades.
How to cut D2 round bar?
Forging and heating a D2 Steel Bar requires slow, even heating. Stop working when the temperature falls below 1700°F, soak through at 1850°–1950°F, and reheat as needed. Cool slowly in lime, mica, dry ashes, or a furnace after forging. D2 must continuously be annealed after forging.
Steels are frequently ground using CBN, which is the second hardest material. Even though CBN is significantly more expensive than standard abrasives, during this process, tools made of CBN are primarily used to cut D2 Steel Round Rods materials with a hardness ranging from 45 to 68 HRC. A finite element model was created to simulate the chip removal process during intricate cutting.
Application of 1.2379 round bar
In long-production cold work applications requiring extremely high wear resistance and high compression strength, 1.2379 steel is frequently used. This AISI O1 (Din-1.2510) Round Rods and Is-T90mn6wcr2 Round Rods have a low order of movement during air hardening and have some corrosion resistance. These are used in various applications, such as knives, shear blades, punches, stamping dies, blanking dies, etc.
High abrasion resistance and shape stability during hardening are necessary to produce a 1.2379 Round Bar. Experts follow this procedure with the aid of developed infrastructure and concomitant factors.
