Vanadis 8 SuperClean .179" Thickness

Uddeholm Vanadis 8 SuperClean

 

This is an “unobtanium” steel. It’s an exceptionally hard to find exotic super steel.

 

We waited for 4 months to track down 1 sheet of the stuff.

It’s expensive. It’s cool. It’s super tough and super wear resistant.

 

We had this waterjet down to 30” long strips in a few widths. We will be selling this only in 30” lengths to avoid awkward drop cuts.

 

This powder metal technology super steel has exceptional wear resistance coupled with exceptional toughness.

 

Have a look at the alloy content.

C 2.3

Si .4

Mn .4

Cr 4.8

Mo 3.6

V 8.0

 

What’s going to be different than most knife steels is the Mo (molybdenum) content and the high V (vanadium) content.

 

HRC64 is your target hardness and is where the Uddeholm engineers suggest you take this steel to.

 

To anneal

Ramp to 1650F and cool at 650F per hour. Basically run it to 1650f in your oven and turn it off.

 

Stress relieve

Hold at 1200F for 2 hours and cool slowly.

 

 

Hardening

Ramp to 1200F and hold 5 minutes

Ramp to 1600F and hold 5 minutes

Ramp to 2010F and hold for 15 minutes

Plate quench while shooting compressed air in between the plates.

 

Temper

Temper 2 hours twice, allowing steel to cool to room temperatures between tempers.

950F for 64HRC

 

Uddeholm recommends not to temper lower than 920F

 

We do not have data for cryo treatment although I suspect it might benefit from a soak in Ln overnight.
