Where is a reputable place to buy 9Cr18MoV steel?

I'm looking at making stainless kitchen knives and think this will be a good option for steel.

Thanks for your help!
 
If you are a custom knife maker, there are better steels.

If you're a company that has things manufactured in China, I guess that's a different story

Thanks, but I'm interested in the steel due to the chromium content.

That's an awesome website! Thanks for the info.

No chromium in the steel you'll be working with if you want to get good at making knives, my guy.

Though seriously if you want a steel for kitchen knives that won’t rust use something like LC200N/Z-FINIT, don’t use 9Cr18MoV there’s so many steel’s out there that are better, and besides anyone that knows anything about steels probably wouldn’t buy a kitchen knife in 9Cr18MoV.

Thats just my two cents.

Can you clarify what you mean by this?

Are/do you:
-Currently make kitchen knives or have ever made one before
-Plan to make kitchen knives by yourself
-Want to have kitchen knives manufactured

Also:
-Are these knives for sale, or personal/friend/family use?

Well, that's why I asked, that's not how that works.

It's primarily the chromium in solution from heat treatment that NOT chromium weight in the steel chemistry.

Here are some available steels from Alpha Knife Supply, they only sell quality steels, which means they're not going to sell 9Cr18MoV

Z-finit has less chromium in its chemistry (15% Cr) than Elmax (18% Cr) yet, its significantly more rust resistant than any other available martensitic stainless on the market besides Vanax. The new CPM MagnaCut has only 10.7% chromium in its chemistry yet is also significantly more rust resistant than Elmax at 18% chromium. In fact, Spyderco moved MagnaCut to their Salt water knife line since it did so well in testing.

So, you shouldn't select a steel based only on its chromium content. Thats not how that works.


I recommend getting some more reading about knife steel from a reputable source.

There is several days worth of reading you can do there that will significantly improve your knowledge and understanding.

I currently make and sell kitchen knives. I'm using Damascus from Alabama Damascus currently and want to get into using stainless. Thanks for your response.
 
That's awesome info. I really appreciate the explanation! I was confused and thought that more chromium = more corrosion resistance. I called AKS and spoke to a guy who told me about the Magnacut. I think I'm going with that steel. I know 9Cr18MoV is cheap, possibly sketchy, stainless, but I bought a knife made with it and it doesn't rust easily at all.

But, I'm going to go with the Magnacut. I want to use quality steel and not have to worry about what might happen down the road to my knives.

Thanks again!

If you want an inexpensive stainless steel, have you considered AEB-L?

Ah, cool cool. I had to ask because there's been a rash of new people who show up and say they are going to make or are making knives, but it turns out what they mean is have their CAD-designed generic titanium frame-lock made in Guangdong. I give them the rail spike litmus test to get to the bottom of it.

I have, but I'm going to use the Magnacut. I know it's quite a bit more expensive, but I want to deliver a quality product that I don't have to worry about. Thanks for chiming in.

I hear ya man. That's hilarious! I do actually grind it out by hand. You can see my work W WilsonKnives on Instagram. I have a lot to learn, but I feel like I'm making good progress. Thanks!
