CPM S110V available to makers?

[James_Terrio]

Sweet jumpin Jesus Christ on a pogo stick, I want some of this stuff but I kinda would rather kick my self in the ballz, than grind it.

No kiddin'. You guys must have way more patience than I do! Anything made of that is gonna wind up mighty pricy, once you figure in labor/time and belts etc.

I'm curious, what was this stuff developed for? They must have had a specific end-use in mind to come up with something that intense...

You guys should try pickling it to get the bark off. Save some belts that way.

Well, I have some updates. It works somewhat easier once the scale is off, but by no means easy. Drilling has been with Carbide bits kept lubed. Grinding was done at low speed using Hoggers to 220g and then switching to Norax. It's getting close to looking like a knife, so I took it to heat treat. Even at 2150, Marilyn's magic worked and it came out nice and shiny from the plates at RHC 63. Overnight in Liquid Nitro and now it's RHC 65! (pretty sure this wouldn't be a good time to drop it on a concrete floor.) It also seems pretty clear that this steel will benefit from cryo. It's in for the first of three tempers now. I'll be aiming for high rockwell, since this blade is supposed to be about wear resistance.

More to follow.

Rob!

Any updates, Rob?

I notice that CPM 10V has annealled hardness 277 Brinells compared to S110V's 400 Brinell. Plus S110V would harden while grinding because of the secondary hardening response. But still, the ceramic belts shouldn't have any problem right? Maybe grinding it by hand on a DMT benchstone would be easier?

In the datasheets Crucible says: "The CPM process results in a fine and uniform carbide distribution in CPM S110V compared to conventionally produced high alloy tool steels which results in relatively good machining, grinding, and toughness characteristics despite the high alloy content."

Im saving mine Im a hoarder of wood and steel . Kellyw Ps rob I ground out 4 more blades today lol

The Niobium alloys are often used in pipeline construction. A pipeline worker may know the best way to cut the steel. He may even have some to make knives with.
