CD#1 Carbon Steel - Extreme Toughness

[Alpha Knife Supply]

We have a limited amount of Carpenter CD#1 carbon steel. CD#1 is made using the particle metallurgy process. It is designed for for extreme toughness and is one of the toughest cutlery alloys available.

Composition:
Carbon:	0.700%
Chromium:	8.250%
Manganese:	0.400%
Molybdenum:	1.400%
Nickel:	1.500%
Nitrogen:	0.090%
Silicon:	1.000%
Vanadium:	1.000%

Carpenter makes some excellent alloys. It is unfortunate that their alloys are difficult to find and buy.

To heat treat CD#1, use the information in the Data Sheet.

CD#1 is available for purchase here.

I would love to see more HRDA offered in the PM steels. I bought a peice as I am a sucker for CD#1.

I've been wanting to make a new blade for my wood chipper...

Your website usually posts some basic heat treat information. However I don't see any for this steel?
Would this be a good choice for a dagger?
Thanks

Never mind.. Larrin Thomas has some recommendations for heat treat.

I bought this steel because people I trust recommend it for knives requiring extreme toughness.

I added a link to the CD#1 Data Sheet. All the heat treat information is listed in the data sheet.

The Gerber Mark II is one of my favorite daggers. It was first made from L6 carbon steel , then was gradually downgraded to different lower quality stainless alloys. My opinion is L6 was originally chosen because of its toughness.

I would love to see more HRDA offered in the PM steels.

For years we sold PM alloys with the hot rolled finish. And for years we received constant complaints from knifemakers who found small pin prick sized pits in the surface of the steel. Each complaint took time to resolve.

Fast forward to a few years ago. We bought a Blanchard grinder and ground some PM alloys for sale. We gradually increased the amount of ground steel until we were grinding all PM alloys.

Since we started grinding we have received zero complaints from knifemakers regarding pits in the surface. The surface of the ground steel is not perfect, but it is very good.

Alloys sold as Sprint Run items will be the exception to our grinding rule.

Ohhh yeah!!!! I've been wanting to try this steel. Able to get harder than A8Mod, presumably a little easier to finish than 3V, a little bit tougher than and about as wear resistant as AEB-L, and stain resistant enough with a lower temp. temper. It isn't as affordable as AEB-L, but if it's more stable in heat treatment it might be worth making it a go-to steel. I just bought some and hope Carpenter makes more.

Thanks for the information. I appreciate it. Sounds like a great option for a dagger...or daggers
Ordering.

NSM has carried it since 2019.

Yeah, I just did a search and saw that. They require a minimum $250 order though. I won't spend that just to find out if I like a steel, but I'll keep them in mind if I do. Thanks for the tip.

ain't no knife in the world sees rougher use than a chipper blade! Been thinking about making some chipper blade sized 'coupons' to experiment with my 3V process but it's tough to find it in the thickness I need. A brusher blade, on the other hand...
