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.

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.
