What is d2 steel – is d2 steel best for knives?

There are many sheets of steel found in today’s world that are used in making knives; d2 steel is one of them. Some of you perhaps already know about d2 steel.

If you are not aware of d2 steel, this article may help you in knowing d2 steel. In this article, we will share all the information related to the d2 steel, and you may find this article helpful.

What is d2 steel?

D2 steel is known as one of the durable and sharp steels which are made from non-powder steel. Some of the d2 tool steel properties are that it provides a powerful combination of toughness and wear resistance, and it requires low machinability. This is the reason that many knife-makers and companies are using d2 steel.

D2 steel is common steel that is used in making long production, hard work, and high wear applications because it provides great edge retention. This steel is also used in the making of knives, blades, and other related things.

D2 steel is also known by different names. Some of the other popular names of d2 steel are German designation 1.2379, Uddeholm Sverker 21, Japanese designation SKD11, and many more.

Chemical Composition of d2 steel

D2 steel is a high-carbon and air-hardening steel that is comprised of the following chemicals:

  • Carbon (1.5 %): It increases the hardness and strength of the steel. It also increases the brittleness and hardenability of the steel.
  • Molybdenum (0.9%): It increases the corrosion resistance, hardness, strength, and electrical conductivity of the steel.
  • Sulfur (0.02%): It increases the machinability of steel.
  • Manganese (0.45%): It decreases the critical cooling rate during hardening, which means it increases the steel’s hardenability.
  • Silicon (0.40%): It also increases the hardness and strength of steel but less than Manganese.
  • Vanadium (1.10%): It is used to control the grain size of the steel and also used to increase the strength and hardness of the steel.
  • Chromium (12%): It increases the corrosion resistance and increases the steel’s hardenability.
  • Phosphorus (0.03): It improves machinability and increases resistance to corrosion in steel.

Rockwell hardness of the D2 Steel

D2 offers a good hardness and toughness with a long-lasting edge, and it has wear resistance properties.

D2 steel is a high-carbon and air-hardening steel, and it has a minimal distortion in heat-treatment relative to other tool steels. It is heat treatable and offers a Rockwell hardness that ranges from 55 to 62 HRC.

FAQ’s

What is the annealed hardness of d2 tool steel?
D2 steel is machinable in the annealed condition. After machining, it requires a hardening to achieve its properties. Annealing must be done after hot working and before re-hardening. The General annealed hardness of d2 steel is 217/255 HB.
How to sharpen d2 tool steel knives?
D2 is a hard steel that’s why it is a bit tough to sharpen. It’s very hard to sharpen d2 steel with a whetstone, but there are other methods that may work. You can sharpen d2 steel with a diamond sharpener or ceramic crock sticks, and these methods will perfectly work.
Where to buy d2 tool steel?
There are many online stores that sell d2 steel. You can buy d2 steel from many online stores. Some famous online stores include Amazon, Southern Tool Steel, Online Metals, Metals Depot, Metal Super Markets, and many more.
How to harden steel for knives?
Hardening is a method of making the steel of a knife harder than it was before. First of all, heat the knife steel between 1050 and 1090°C and after that quick quince it. In this way, the knife steel will become much harder and more brittle than it was before.
What is stronger d2 tool steel or 154cm stainless steel?
Both of these steels are good, but D2 steel is much harder than 154cm steel. D2 steel is semi-stainless steel while 154cm is stainless steel. D2 steel is more abrasion resistant and tougher than 154cm steel. In my opinion, d2 steel is a better choice for larger blades.
How to weld d2 tool steel?
D2 tool steel can be welded in annealed or hardened conditions. For annealing pre-heat, the steel in 370-485°C temperature and for hardening pre-heat, the steel in 15-30°C below the actual temperature.
