New forge steel, ApexUltra

[dirc]

The article says it has high toughness even when it’s very hard, and that at a somewhat lower hardness it should be really tough (close to 80crv2 on the graph). I guess we’ll see!

apexultra seems to get around 10 ft-lbs at 65... but isn't tested to lower hardness
while 80crv2 is 30 ft-lbs at 61 hrc

I'd love to see how tough it could get... if anyone has tested at lower hrc, please share results : )

Well if it ends up similar to 52100 at 61, as Larrin postulates, it should be plenty tough.

or... could do a san mai.... 1/16" of apexultra with 1/8" outer layers of 8670 ; )

weld that up and you're all set, and bobs yer uncle

Looks like they rolled out the first size, 5mm 120mm. It should be arriving from the mill in a couple of weeks.

Can't wait for the 0.060" thru 0.080" for stock removal! Those etching stencils shown on the IG updates look pretty cool! Have to have some of those as well.

I want to forge a 1/8" bolo machete or gladius from some apexultra...
just saying

So what existing steel is a close relative to this new stuff?

52100 or Super Blue - honestly nothing. define "close"

Larrin the spec sheet indicates a "wide" range of the austenitizing temp-
Austenitize between 780 °C (1435°F) and 880°C (1615°F)
This is a great feature indeed.
Question - no grain growth at the higher hardening temp?

It needs higher than that to start seeing grain growth.

Apex ultra does but not 1095. Explain low alloys and carbon and temps to people Mr God. Jesus Christ or would you like me to?

 

[Super_Alloy_Alan]

The answer is the additional alloying in a sentence. I'll explain more later but a small amount of anything does A LOT. And it's not so much the W addition because of it's molecular weight. I would assume everyone here knows this but small amounts of vanadium will pin grain boundaries henceforth growth. I'll get into it more when I can type more

I dont understand your ire, Alan. Larrin Thomas has contributed vast amounts of knowledge to this forum, free of charge. Maybe since you only joined last week you've missed much of that

A Very strange way to respond…
I realize we don’t get the benefit of your tone but….

Never mind gents, it's the return of a previously banned member under various guises. We'll keep banning him each time he reinvents himself.

Carry on. Sorry for the disruption. I should have known it was him...but I didn't bother to check until just a couple of minutes ago.
