New Steel CPM MagnaCut available today

For what purpose?

For PVD coating. And there is commercial HT company who regularly run this recipe(HSS) at reasonable price so I can send it along.

For now I only have high temp salt bath as high alloy HT equipment and I try to avoid running it at over 1925F.

Using 1000F leads to a reduction in corrosion resistance for any steel, and every steel I’ve tested with toughness was also somewhat lower.
 
Thanks, Richard. Unfortunately, they were out of .093. But they did have one stick of .065 so for that. I also had toner a stick of .093 com 154 to get me over the $100 minimum order because they only had one stick of the magnacut left.

Larrin Larrin , Do you think the corrosion resistance and toughness will drop down significantly if I use 2150F austenitizing and 1000F tempering?

If you have to do 1000° to cover over tempering from your PVD coater you need to find someone else. A customer of ours tried a few places and found out temps vary wildly. But it’s usaly to speed up the process and make more money. He found BBC a place that’s u set 400° I believe. We where considering changing his M4 heat treat to alow him to use the cheeper Pvd but decided that was a bad idea in the long run.

I would take half of that order of your hands if you weren't planing on ordering that much, I would cover the cost of shipping of course :)
 
I think I got the last two bars of .063".
Should make super-slicers and fillet knives.

I'll have to review the data and decide how thin an edge and how hard I can go.
 
Let me know what you come up with, Stacy. I was planning on taking the edge thickness down to .020, maybe even .015 with a hardness of around 62.
 
Congratulation Larrin Larrin on seeing this steel come to fruition! I appreciate the hard work and dedication that it took to accomplish this.
I'm glad I was able to snag a few bars.

0.093, 0.125, and 0.156" is all sold out.

Ahhh can't believe I missed it! The others look a little thick for what I need them for... Do you have any idea when production will begin so more is available? Will it still be a yearly or two?
 
Congratulations on your accomplishment, Larrin. Is the price likely to go down when production picks up, or am I going to need to rob a bank? Also, waiting on answer to someone's earlier question about need for foil wrap (I'm guessing yes)?

The price is about the same as other CPM steels. The price can vary some based on supplier. Niagara will sell sheets to other suppliers and sometimes their costs for shearing different sizes is less.

Anything above about 1600F needs atmosphere protection of some kind. Foil is the easiest way.

I was thinking Rc 62, near zero edge thickness, sharpen at 10-15DPS. I'll definitely do a post on my results.
