Here's what happens when you get it too hot...

i have to say, i'm actually impressed. how did you even do that?

 

[mete]

That must have goten VERY hot , probably enough to melt the grain boundaries !!

 

[deker]

Wow Phillip! Is that O-1?

-d

 

[Nathan the Machinist]

Uh... yeah... You're gonna want to back off that heat just a little bit there...

I'll bet it hurt your eyes just to look at it. From the heat I mean.

What temp was it at? I thought steel would melt rather than crumble. Or, am I not realizing what I am seeing?

 

[Don Hanson III]

Wow, that's a good one, Phillip!

 

[Robert Dark]

Woof....... That sux. What is (was) the steel and what were you trying to do?

A few years ago, I sent one directly to the Sun and it came back looking that way. Next time I am gonna send it a night.

 

[DaveMartell]

What do you guys think happened here? Am I seeing stacks where the welds melted?

 

[jdm61]

Funny. The best one that I have seen was a newbie forging at the green coal forge at Batsons. He put in a bar and got to talking and when he pulled it out, it was about 3-4 inches shorter than when he put it in....and it wasn't O1. It was W2.

well then that looks liek soem fun high alloy steel that was san maied and taken to about 2400f
not that i have seen a mess like that before

 

[Fletch Helical]

Yeah Phillip we need a bit of the dirty details of how that came about

 

[mete]

Steel is not uniform as the grain boundaries are of higher energy levels. Brittleness can be caused by oxidation of the grain boundaries and melting of the grain boundaries before the grains themselves melt.

 

[bacustomknives]

looks like a 2000 degree water quench lol, good one!!

 

[sharpeknives]

Got to texting and forgot about it did ya? Cell phone bad! Hammer anvil good!

 

[richard j]

hey phillip, are you turning that into a wall hanger

 

[Wulf]

that's awesome were you working on a stainless / carbon laminate?

 

[Phillip Patton]

Hey,
Richard, not a bad idea.

I was trying to laminate 440c and A2. I think it would have worked. :foot:

I'll try again at a lower temperature and let you know the results.

Honestly, I should have known better, I just had a brain fart. High carbon steel welds at lower temps than mild steel. Probably the same principal applies for stainless and tool steels.

 

[butcher_block]

yep
i think your right

 

[rhrocker]

I was getting really jealous there for a minute. I thought you had been to my house and talked my wife out of her cornbread recipt. Looks identical!
