Choosing a perfect steel tool can be difficult. On top of that, Crv steel and S2 steel both have conflicting characteristics. So, getting confused between these two is normal.
So, which is the better steel tool in CRV steel vs S2 steel?
Firstly, the key element of Crv steel is Chromium whereas s2 steel is Silicon. Then, the melting points of both steels are 2786°F and 2590°F. Also, the machinability rate for Crv steel is 59% and s2 steel is 85%. Lastly, Crv steel requires 2200°F for forging whereas s2 steel needs 1600-2000°F.
These facts are confusing. But don’t be worried! We covered everything in this article that will help you to make a decision.
Without wasting any time let’s dig in!
Quick Review
We need to first understand the basics. Hence, let’s first address what is Crv steel? Crv steel means chromium-vanadium steel. It is high-speed steel, which is commonly used for tools.
Likewise, you might be wondering what is s2 steel? S2 steel is a shock-resistant tool steel. Because of its component, shock impact can be transmitted to the alloy. This allows working for a longer period.
Dewalt hand tools are mostly produced using these two types of steel. It is very handy for people and mechanics as those steels provide top-notch service.
Nevertheless, both steels are different and usage varies according to tools. Now, let’s look at some basic differences.
| Differentiating Factors | Crv Steel | S2 Steel |
| Key Element | Iron and Chromium | Iron and Silicon |
| Density | 0.284 lb/in3 | 0.281 lb/in3 |
| Melting Point | 2786°F | 2590°F |
| Machinability Rate | 59% | 85% |
| Temperature for Thermal Expansion | 72°F | 68°F |
These are the basic information of the tools. Yet the information isn’t enough to provide a solid answer to your question. So, we need to go deeper.
Let’s move to a more comprehensive discussion on the difference between CRV steel and S2 steel.
In-Depth Comparison
This portion will provide enough information to choose which steel is better for your tools. There are lots of different characteristics that distinguish these steels. For the components and reaction to heat, these steels are used in different tools.
Hence, let’s see all the detailed information.
Elements Used
Even though the main element of both steels are Iron (Fe), there are a few differences.
For starters, Crv steel is carbon-based steel. The other components of this steel are Chromium, Manganese, Carbon, Vanadium, Sulfur, and, Phosphorus.

On the other hand, the other components of s2 steel are silicon, Carbon, Molybdenum, Manganese, Vanadium, Phosphorus, and Sulfur.
Now, the question arises. Is S2 steel good for screwdrivers?
Obviously, yes. S2 has all the quality elements favored in screwdrivers. They are really durable and can be used for heavy-duty work.
So, it can be said that S2 is hard steel compared to Crv steel. That makes every S2 steel tool more suitable for tough steel jobs. However, Crv steel is more flexible than S2 steel.
Physical Properties
Here, the density of Crv steel is 0.284 lb/in3. The melting point of Crv is 2786°F
However, the density of S2 steel is 0.281 lb/in3. And the melting point is 2590°F.
So, Crv steel needs more temperature to be forged or welded compared to S2 steel.
Machinability Rate
Machinability rate describes the ease with which a tool can be welded or forged. The lesser machinability rate indicates it requires more work.
With that said, Crv steel’s machinability rate is 59%. Compared to that, s2 steel’s machinability rate is 85%. As a result, Crv steel requires more work and time than s2 steel.
Welding
Welding is a way to fuse two or more steel parts. It can be done by applying heat or pressure.
Crv steel follows the standard welding procedure. But preheating and post-weld stress relief are two important parts. If these things get messed up, then welding Crv steel will become impossible. Even worse, the steel may become unusable.

On the other hand, s2 steel also follows standard welding procedures. Either by applying heat or pressure you can weld the steel together. In contrast to Crv, no extra precaution is not necessary.
Welders are not cheap. But a good welder can offer high-quality welding jobs you won’t get from mediocre welders. So here are some top-quality welder we recommend for you:

Heat Treatment
At 1600°F, Crv steel is hardened. This steel is tempered. After that, it is standardized by air-cooling at 1650°F.
In terms of s2 steel, it slowly warms at 1200°F. Then, by increasing the temperature to 1600°F, it is directly heated. Afterward, the steel is held for 10 to 20 minutes before being quenched in water.
S2 steel requires less temperature to complete heat treatment compared to Crv steel.
Forging Temperature
The forging of Crv steel takes place at a temperature of 2200°F.
However, s2 steel can be forged between 1650 to 2000ºF. So, again forging temperature for Crv steel is higher than Crv.
Using a foundry furnace for forging like Tabletop Quickmelt is ideal in both cases. However, there are different types of furnaces using different metals as well.

Annealing
Crv steel is air-cooled after being annealed at 1550°F. In contrast, s2 tool steel is annealed at 1450°F. Then it is cooled in the furnace at a pace of 4°C per hour.
Applications
Now comes the last part. Which tools use Crv steel and s2 steel.
Crv steel tools are chainsaw, miter saw wrench, drill press, bandsaw, etc. These tools need to be flexible. And, even though Crv steel is less tough than s2 steel, it is more flexible.
On the other hand, s2 steel properties are strong and have the ability to absorb impacts. So, s2 steel tools are the hammer, screwdriver, wire strippers, etc.
The tools are very much different for both steels. However, all the tools are necessary for any workshop.
The drill press and bandsaw are very famous tools for a woodshop. Each has pros and cons. So, before buying, it’s best to go through the comparison between drill press or bandsaw.
That’s all about the in-depth comparison. This will guide us to deciding the next step which is to choose the appropriate steel.
Deciding The Appropriate Steel For Your Tool
Both of these steels have different characteristics. For which different tools require different steel.
You might be wondering,
Is S2 steel better than CRV?
Well, If you want to produce tools like chainsaws, wrench, etc. then Crv steel is appropriate. Because the steel is flexible and doesn’t get dull. However, for tools like hammer, drill, or screwdriver s2 steel is better. Because the steel is strong and can handle impacts.
In different scenarios, these steels are being used. So, choose a steel tool wisely and according to your demands.
FAQs
How Strong Is Crv Steel?
Crv steel is stronger and more durable than carbon steel. As a result, it’s an excellent material for high-end tools.
Can S2 Steel Be Hardend?
The composition of S2 steel can be changed to influence its hardenability. They can achieve optimal hardness by austenitizing at elevated temperatures.
Do Crv Steels Rust?
Chromium-Vanadium Steel or Crv steel has excellent corrosion resistance. For which it is resistant to alkalis, sulfuric, and hydrochloric acids. So, CRv steels don’t rust.
Conclusion
That’s all from us! We have covered every important aspect regarding Crv steel vs s2 steel.
Here is a tip, always buy a tool based on their grading point. The better the point the longer the tool will last.
Take care and stay updated!
