D2 Tool Steel vs 1095 Carbon – What’s the Difference

D2 Tool Steel vs 1095 Carbon

Choosing the right steel for your project can take time to choose between the numerous options available. Two of the most popular steels are D2 Tool Steel and 1095 Carbon. They both have a range of applications and their unique properties. In this blog post, we’ll explore the key differences between D2 Tool Steel and 1095 Carbon so that you can make an informed decision about which one is right for you.

What is D2 Tool Steel?

D2 Tool Steel is a high carbon, high chromium-based alloy tool steel. It has excellent wear resistance and toughness due to its lengthy hardening process, which includes air cooling after heat treatment. D2 Tool Steel also offers superior corrosion and abrasion resistance, making it perfect for various applications, including dies, cutting tools, knives, punches, etc. Additionally, the hardness of the tool steel can be adjusted to meet specific requirements depending on its application.

What is 1095 Carbon?

1095 Carbon is a type of high-carbon steel used in swords, knives, tools and other metal items. It has a carbon content ranging from 0.90-1.04%, which makes it a very hard and durable material. This hardness also makes it highly resistant to rusting and corrosion, common problems with low-carbon steels. Its high tensile strength means that 1095 is harder to shape than other types of steel, but it can still be machined into shapes easily enough for use in swords or knives if needed.

Difference Between D2 Tool Steel and 1095 Carbon

D2 tool steel is a high carbon (1.50%), high chromium (11%) air-hardening cold work tool steel designed for long-lasting cutting and shearing applications. 1095 carbon is a high-carbon, low-alloy plain-carbon steel with a nominal 0.9% carbon content forged for use in tools and knives due to its higher hardness and heat treatability than other steels such as 1045 or 1080.


The primary difference between D2 tool steel and 1095 carbon steel is their composition. D2 tool steel comprises approximately 1.4% carbon, 12% chromium, 0.7% molybdenum, and 0.7% vanadium, while 1095 carbon steel comprises approximately 0.95% carbon and 0.45% manganese.


Due to its higher levels of chromium, molybdenum, and vanadium, D2 tool steel has a higher hardness than 1095 carbon steel, with a Rockwell hardness rating of 59-61 compared to 56-58 for 1095 carbon steel. This makes D2 tool steel more suitable for applications that require greater wear resistance, such as cutting tools or dies.

Corrosion Resistance

D2 tool steel also has superior corrosion resistance compared to 1095 carbon steel due to its higher levels of chromium which provides it with greater rust protection than 1095 carbon steel which does not contain any chromium.

Heat Treatment

Another key difference between D2 tool steel and 1095 carbon steel is their heat treatment requirements; D2 tool steel must be heated to a temperature of 1000°F (538°C) to achieve maximum hardness, while 1095 carbon only needs to be heated to a temperature of 1500°F (816°C).


Finally, the cost difference between the two materials can also be significant; due to its superior properties and heat treatment requirements, D2 tool steel tends to be much more expensive than 1095 carbon steel which is more readily available on the market at lower prices.


In conclusion, D2 Tool Steel and 1095 Carbon Steel are excellent choices for different applications. D2 Tool Steel is better suited for high-stress applications requiring excellent wear and corrosion resistance. At the same time, 1095 Carbon steel is a more affordable choice and ideal for applications requiring sharp-edge retention. Both steels require proper heat treatment to maximize their strength and durability, and proper care and maintenance are important to ensure their longevity. Ultimately, choosing these two steels depends on your specific needs and preferences.
