D2 Tool Steel 1.2379

Q: What is D2 tool steel grade?

D2 steel is a high-carbon, high-chromium tool steel. D2 is one of the most well-known tool steels due to its extreme wear-resistant properties and toughness.

Q: What is D2 tool steel used for?

D2 is commonly used in cold work applications, mainly used for tools where there is high wear and abrasion.

Q: What is the equivalent of D2 tool steel?

D2 material is part of the Cold Work Tool Steel family. DIN 1.2379, AISI: X153CrMoV12

Q: Does D2 tool steel need to be hardened?

D2 steel needs to be hardened to maximise the steel's hardness and wear resistance.

Q: Is D2 tool steel good for knives?

D2 can be used for knives because it can hold an edge and maintain its hardness, with good resistance to wear and corrosion.

D2 TOOL STEEL SUPPLIER

D2 is one of the most well-known tool steels due to its extreme wear-resistant properties and toughness. These properties combined limit tool failure through breaking, chipping, cracking or premature wear. This grade provides an edge that will stay sharp for a long time.

Supplied Condition:

D2 steel supplied in the soft annealed condition to max. 255 HB.

We bandsaw cut D2 plates, rounds, flats and squares to your requirements.

Why choose AKM Steels for D2 tool steel?

Reliable UK supply — D2 is held in stock in a range of sizes and forms, helping keep lead times short.

The right grade for the job — Our team can confirm whether D2 is the best fit for your tooling, or whether an alternative cold-work grade would perform better.

Specify with confidence — Supplied to recognised specifications, with certification and testing available where required.

More than just steel — Cutting, machining and grinding available to reduce your handling and procurement.

D2 Tool Steel Chemical Composition (%):

C	CR	Mo	V
1,55	12,00	0,80	0,90

D2 Tool Steel Properties
Air-hardening, 12% chrome steel
Composition & properties are close to stainless steel
High volume of hard carbides (C, Cr) → High levels of wear resistance & toughness
Excellent dimensional stability & high compressive strength
Secondary hardening properties → Good base material for coating & nitriding

Typical Applications of D2 Tool Steel

The properties of D2 mean it is mainly used for tools where there is high wear and abrasion:

Press tools
Cutting, punching, stamping
Knurling tools
Blanking tools
Crushers
Shear blades
Thread rolling dies
Cold extrusion dies
Deep drawing & bending tools
Flanging & straightening rolls
Fine-cutting tools
Plastic moulds for abrasive polymers

Soft Annealing D2

Temperature	Cooling	Hardness
820 - 850 °C	furnace	max. 255 HB

Stress Relief Annealing

Temperature	Cooling
600 - 650°C	furnace

Hardening D2 Tool Steel

Temperature	Cooling	Tempering
1000 - 1030 °C	oil, pressure gas (N²), air or hot bath 500 - 550 °C	see tempering diagram, usually < 300°C
1040 - 1080 °C	oil, pressure gas (N²), air or hot bath 500 - 550 °C	see tempering diagram, usually < 480°C
