UDDEHOLM VANADIS® 4 steel

To what other steels would the toughness of Vanadis 4 Extra be comparable?
 
Here are some pics of the prototype of the knife made from vanadis 4 Brusletto will be offering

I wonder how Vanadis 4 extra will compare to CPM M4, too much carbon for 3V comparisons.
 
Sounds like it is targeted at users looking for high resistance to adhesive wear, but with claimed higher hardness, higher abrasive wear resistance, and higher resistance to chipping than D2 or M2, I'd like to try it in a thin cutter.

For those who don't want a tacky knife?

Vanadis 4 Extra is surprisingly tough for how much carbon it has, at least according to Uddeholm's numbers. I would place it between 3V and CPM-M4, less tough than 3V but tougher than CPM-M4 and less wear resistant than M4 but more so than 3V. This is of course without testing. Vanadis 4 Extra has around 8% carbide volume, 3V around 3-5% and CPM-M4 around 12% carbide volume. 3V and Vanadis 4 Extra only have vanadium carbide where CPM-M4 has vanadium and molybdenum/tungsten carbide.

There's also a patent application for what looks like a Vanadis 6 Extra that looks promising, much more balanced than the current Vanadis 6.
 
Just heard Uddeholm has designed a completely new steel which will be used in the Brusletto knife.
Name was not mentioned.
So it's not vanadis 4E, maybe vanadis 6E (or Vanax 75)?
Focus was on strength and stainlessness
 
Not very nice of J_Curd to not come back and say what steel and manufacturer. ;)

I think he was referring to a couple of Kershaws.

The Speedform will use Uddeholm Elmax

Here are a couple of PDFs I found

And the Volt will use Bohler M390

I think this is the right info sheet about this steel.

Seem like some interesting steels.
 
I'd be amazed if they used S390DE in a knife. Really, really amazed! They could run that high speed steel at RC67-68 if they wanted. It's like using a "T" series steel. Never happen. Joe
 
I have used Vanadis 4 E quite a lot in knives.
Here is an article on Vanadis 4 E (unfortunately in Norwegian):
http://kniver.blogspot.com/search/label/Stål - Vanadis 4 Extra

Vanadis 4 E is obtainable in 5,2 mm sheets. I use both that and 10*50 mm bar.

Vanadis 6, Vanax 75 and Elmax are less suited for knives, as the higher alloy content lead to increased carbide content and higher brittleness. That in turn demands a higher edge angel to avoid chipping.

It is not possible to compare powder steel from Crucible and Uddeholm or Erasteel directly, as the atomization process used are different. Crucibles process is more suited for HIP’ing directly to shape, while Uddeholm/Erasteels process are suited for forging and rolling to sheets.
I tested CPM 3V once, and didn’t seam to get any higher toughness than I have on Vanadis 4 E, even thought the much lower carbon content in CPM 3V should have lead to a much higher toughness.

Ty will not be produced in an advanced steel like Vanadis 4. It will most likely be produced in a conventional stainless steel.
 
Thank you for the info Fredrik.
You make knives in both vanadis 4E and Chipper/Viking.
How do these compare to each other?

Different steels for different use.

I use chipper for larger knives designated for hard/tough use. (Military, survival and wood work.) This steel has a very high toughness with good wear resistance, when hardened to 58-62 HRC. This steel is very similar to Busse combat’s INFI.

Vanadis 4 E is used in hunting knives, and the combination of wear resistance, hardness and toughness should make it one of the best steels on the market for knives where edge holding is the main aim. I heat treat Vanadis 4 E to 63-66 HRC depending on the use.
 
Out of the gso5 in cmp3v by survive! Knives or the Knife Research Enki Fixed Blade in Vanadis 4 Extra steel what knife would you choose? My intended use will be going bush with it and using it as my primary knife while building shelter, food prep, fire prep.
 
Possibly wait for the upcoming ZT 0180 with Rick Hinderer design based on his FieldTac with under $200 pricing!

  • Steel: Vanadis 4 extra, tungsten DLC coating
  • Handle: Machined G-10
  • Blade Length: 4.2 in. (10.7 cm)
  • Overall Length: 9.2 in. (23.4 cm)
  • Weight: 8.7 oz. (246.6 g)
 
From what I understand, CPM 4V is similar to Vanadis 4E. Both are above 3V from what I've read. CPM 4V and Vanadis4E have close material properties. I just got a knife from Big Chris with the CPM 4V and it is impressive.
