When it comes to knives, there are many different types of steel available on the market. Two of the most popular types are d2 and s30v. So what’s the difference between them, and which one is better? Let’s take a look at both so you can decide for yourself.
D2 Tool Steel
D2 tool steel is an air-hardening, high carbon, high chromium steel with very good wear resistance and a maximum hardness of 60HRC. It has great toughness with excellent strength properties that make it a great choice for knife blades because it offers superior edge retention without sacrificing sharpness or strength. D2 also has great corrosion resistance, making it ideal for outdoor use in wet climates. The only downside of d2 is that it requires special heat treatment processes to be effective, so if you’re going to buy a knife with a d2 blade, make sure it’s been properly heat treated by someone who knows what they’re doing.
S30V Steel
S30V steel is another popular steel used in knife blades today. It’s manufactured by Crucible Industries in the United States and is composed of carbon (1%), chromium (14%), molybdenum (4%), vanadium (3%) and other trace elements like nitrogen and phosphorus. This combination makes S30V extremely hard (59-61 HRC) while still maintaining its ability to hold an edge better than most other steels. It also offers superior corrosion resistance compared to other steels, making it well suited for outdoor use in damp climates as well as kitchen use where food acids might cause staining on other types of steel blades.
Difference Between D2 Tool Steel and S30V
Composition
D2 tool steel is composed of 1.5% carbon, 0.60% manganese, 11.00% chromium, 0.30% vanadium, and 1.10% molybdenum. S30V steel is composed of 1.45% carbon, 14.00% chromium, 3.00% vanadium, and 2.00% molybdenum.
Hardness
D2 tool steel has a hardness of 60-62 HRC on the Rockwell scale, while S30V steel has a hardness of 59-61 HRC on the Rockwell scale.
Edge Retention
D2 tool steel has excellent edge retention due to its high carbon content and high chromium content. S30V steel also has excellent edge retention due to its high carbon content and high vanadium content.
Corrosion Resistance
D2 tool steel is highly resistant to corrosion due to its high chromium content. S30V steel is also highly resistant to corrosion due to its high vanadium content.
Toughness
D2 tool steel is considered to be tough due to its high chromium content, which provides wear resistance against abrasion and wear. S30V steel is also considered to be tough due to its high vanadium content, which provides wear resistance against abrasion and wear.
Price
D2 tool steel is typically more expensive than S30V steel due to its higher carbon content and higher chromium content.
Conclusion
When deciding between d2 tool steel vs s30v steel for your next knife purchase, consider your intended purpose and environment – whether you plan to use your knife indoors or outdoors, whether you need more edge retention or more corrosion resistance, etc. Both d2 and s30v offer great performance, but their individual characteristics may make one more suitable for your needs than the other – so do your research before you buy! No matter which type of steel you choose, make sure that your next knife has been properly heating treated by someone who knows what they’re doing – this will ensure that your blade will perform up to its fullest potential!
