What is D2 Tool Steel?
D2 Tool Steel (1.2379) is a staple of the tool steel industry, having been with us for many years. It is one of the most well-known and popular grades of tool steel due to its high levels of wear resistance and toughness resulting from a high volume of hard carbides (carbon & chromium) in the structure of the steel. Other key properties include particularly good dimensional stability and high compressive strength. D2 Tool Steel comes under the Air Hardening sub-category of Cold Work Steels and its composition and properties are close to stainless steel.
If you need an edge that will stay sharp for a long time, and to avoid tool failure by breaking, chipping, cracking or premature wear, D2 Tool Steel will likely serve you well.

D2 Tool Steel is mainly used for tools where there is severe wear and abrasion:

AKM’s D2 Tool Steel Tip:
Whilst D2 Tool Steel is a great all-round tool steel, the metallurgy of tool steels is complex, so if you need any help determining the best steel for a given application, please get in touch with details of your intended usage. There may well be a new specially developed next generation tool steel that will perform even better for your required application.
