InformationCruForgeV Carbon Steel Information and Composition

Condition:
Our CruForgeV has been properly annealed and is in the soft condition. You do not have to do any non-standard wasteful processes before heat treating. The steel must be heat treated to get to a hardened state. Follow the heat treat recipe and the steel will harden.

Ratings:
37 = Maximum Toughness
32 = Maximum Edge Holding

The rating scale is 0-100, 0 being minimum and 100 being maximum. The ratings are the maximum potential of the alloy. I do not recommend heat treating to the maximum value. Choose a heat treat recipe that results in the attributes you want.

Thank you to Dr Larrin Thomas for all the testing he performed and information he has provided. Buy his book Knife Engineering to learn more about knifemaking.

Alloy Comparison Table:

Description:
CruForgeV was developed specifically for forging into knives. Crucible coordinated with knifemakers when developing the steel. The result is an excellent steel that forges and performs very well.

CruForgeV is easy to forge but tougher to finish than any of the 10XX steels or 52100. The tradeoff is edge holding. The vanadium in CruForgeV makes it hold an edge longer than the 10XX steels and 52100.

Flat Ground:
Any alloy that has “Flat Ground” in the description has been Blanchard ground. Our tolerances for flat grinding are +-.001” across 12”. You can identify Blanchard grinding by circular grind marks. Do not be mislead by other descriptions. Others try to pass off less accurate types of grinding with lower tolerances as flat grinding. This is why we call out our tolerances.

Information Sources:
There are many sources of information regarding knifemaking. Some sources, like Dr. Larrin Thomas of Knife Steel Nerds, are excellent. Other sources are not as credible. It is important to vet the your information sources. Be careful of anyone who says the way to heat treat 1095 or O1 is to heat to non-magnetic and quench in used motor oil. Anyone who publishes this type of information is not credible. When possible, we use information from manufacturers and industry experts.

AI Information:
The latest trend of bad information is from Artificial Intelligence (AI). Multiple companies have AI programs. AI collects and compiles information. The problem is, AI is does not know if the information is accurate or garbage. When asked, AI regurgitates and merges good and bad data. Beware of AI data when researching materials. If you read material information that sounds like it was written by a poetry graduate student, compares materials that are not similar, contains blatantly false information, etc, it was probably AI generated. At AKS, we never use AI to generate material information.

Heat TreatCruForgeV Heat Treat Information:

Austenitize: It is critical to not exceed the maximum austenitize temperature. If you overshoot the maximum temperature by a small amount, toughness will go down dramatically.

Heat to 1,500-1,550°F. Equalize temperature.

Quench: Medium oil quench.

Temper: Double temper at 400-500°F recommended. Approximate hardness after double tempering is shown below.

CruForgeV Carbon Steel
Average rating:

Hope to see more available soon. Harder to hand sand and sharpen but better edge retention is a wonderful trade off.

 by Tom

I have to say that I'm sad that this steel isn't available anymore. I made a knife from it and it preforms unbelievably well. Holds and edge exceptionally well!!!. After hours of cutting it still shaving sharp. It is harder to sharpen then other steels but to me it's more then worth the pay off. I'd love to see this made again.
