Information154CM • CPM 154 • CPM 154F Information and Composition

These stainless steel alloys have the same composition and are listed together. There is a filter so you can select one, two or all three of the versions.

What are the differences?

154CM - This variation has been around for decades. It was first developed for use in aerospace. It was popularized for knifemaking by Bob Loveless. It is made by melting the elements and casting a billet.

CPM 154 - In 2004 Crucible took their 154CM alloy and produced it using their CPM process. Using the particle metallurgy process resulted in finer carbides that are more evenly distributed in the finished steel. We refer to this alloy as CPM 154

CPM 154F - In 2022 Crucible made an upgrade. They took the finest CPM 154 powder and used it to make billets. The result is a steel that takes hand finishes and mirror polishing very well. We refer to this alloy as CPM 154F.

Difference Summary:
There are three different variations of the same alloy at three different price points. Choose what best suits your needs. The edge holding is OK and the toughness is good. Collectors like it because it looks good and is easy to sharpen. The carbide producing elements are chromium and molybdenum so it is relatively easy to get a nice hand rubbed finish.

Condition:
All the variations have been properly annealed and are 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.

Alloy Comparison Table:

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.

CPM 154 Data Sheet

Heat Treat154CM • CPM 154 • CPM 154F Heat Treat Information:

Preheat: Heat to 1,400 and equalize temperature.

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.

Increase temperature to 1,900-2,000°F and hold for 30-60 minutes.

Quench: Plate, air or positive pressure quench.

Temper: Two times at 400-1,200°F for 2 hours minimum each time. Cool to room temperature between tempers. Note: Tempering at 800-1,100°F results in a minor reduction in both corrosion resistance and toughness.

Cryogenic Treating: A cryo treatment is recommended after quench. Cryogenic treatment must be followed by a temper.

So far I like the ability to mirror polish this alloy.
