• Spring cleaning sale: I've reduced prices on the BladeForums.com Logo Tshirts and PVC patches to move these out of here! We're down to sizes Large & XL on the shirts, but have plenty of every colorway left on the patches. Get them before they are gone! https://www.bladeforums.com/help/bfcmerch/
  • The search engine is not working correctly. We are aware of the problem and are working on a solution. Thank you for your patience.
  • I've implemented new password tools to try and cut down on the number of people getting their profiles compromised by reusing the same passwords that they have used elsewhere. If you are using a password that has been exposed in a data breach and is listed on haveibeenpwned.com you will get a notification to change it the next time you log in. When you choose a new password it will show you the strength; you will need a "Medium" strength or higher password for here, 8 characters or more in length.

    Thanks for your support!

The alternative steel is also available only in blocks.
Both will be saw. I am waiting the actual availability for both.
Usually those are low stock. They are expensive and available sizes are often unattractive. Round block or big dimension.

Yeah it is often like that unfortunately. Expensive and big blocks. But i guess the steel companies don't want to set up a whole production for a steel thats only being sold in small quantities. It would make it a even more expensive, and they would sell even less.

I would love to hear what the other steel is by the way :)

So this means you have decided what steel to use? Well it's no secret that i'm hoping for K490 at RC 62 :D

When do you have a render ready to show at the forums? Or perhaps it's to early to even ask :)

How would K490 compare to vanadis 4E ?

;)

impact energy unnotched in joule

K890 at 60Rc is 105 j
K890 at 62Rc is 95 j
K490 at 62Rc is 80 j with the almost the same wear resistance as M4

Uddeholm Vanadis 4E ( Crucible has now created cpm 4V with the same make-up)

at 58 Rc is 70j
at 60 Rc is 60j
at 62 Rc is 50j
at 64 Rc is 40j

See for comparison : http://corse76.altervista.org/col.php?noti2=resilienza

I believe wear resistance is slightly less than M4

All steel that you write are third generation powder metallurgy. Croucible is second generation.
There is another steel that I'm even considering that it is not in the list....

But now Enki is coming...
Let's see if we can match the data Uddeholm or we can do better.
Up to now we have always done better.

I thought that Crucible was evolved to second.... I am wrong.

I this moment i think that very high quality steel metallurgy is made in Europe. It's the reason because i'm using those steel.

The CPM 4V has a little bit more impact resistance at 58RC than the Vanadis, but at 60 and 62, it is almost exactly the same. I am not sure what the abrasion/wear resistance of the Vanadis 4E is, but the CPM 4V is supposed to be about the same as CPM S35V.
