steel bar that says "wolfram"

I got a steel bar from my buddy, stamped into one end it says "WOLFRAM", I know that means tungsten, but does anyone have any info on what it might be, or what else it might contain? Has anyone ever seen this?
 
Perhaps tungsten. They are using this for jewelry etc. Perhaps a tungsten tool steel.Check with a magnet. Tungsten is very heavy more so than steel.
 
This is what I found out about it on google.
Steel containing tungsten with other alloys; formerly used for cutting and forging tools but replaced by high-speed steel.

from what I've heard alloys with high tungsten contents can be quite difficult to properly heat treat but don't really have any other benefits. It is possible that you have a bar of tungsten but I feel like it would be noticeably heavier and have a darker, less shiny appearance.
 
Sam, pictures and bar size... NOW! :)

Is that noise sensitive neighbor gone yet or are you still still stuck with hand forging only?
 
Hey Sam, still haven't seem any pics of the grinder explosion aftermath. Still waiting . . .

Tungsten is MUCH heavier than steel (close to the density of lead) and its melting point is considerably higher (which is why it's used for ligntbulb filamants) If you can melt steel on it without it melting its probably tungsten

Tungsten carbides are very wear resistant therefore the use of tungsten in tool steels. It's not that they are so difficult to HT but are difficult to grind !!

Unrelated, but what would you say is better, the molybdenum steels (M series) or the tungsten steels (T steels)? The M-series seem very easy to grind, at least in its annealled state.
 
Better ? With so many alloys it's hard to generalize.Some alloys have developed due to avilability of material .IIRC tungsten was more available in Europe and the USA had lots of Mo. Some of the tungsten steels have 18 % W !! . Tungsten tool steels also have a deep red spark when spark testing - it's very obvious.
 
Well it's not heavier than steel of the same dimensions, so it's definately not tungsten completely, I think it is a tungsten alloyed tool steel, just thought someone might have seen some before, coulda swore I remembered it being mentioned somewhere.


Page you can keep waiting, would you have wanted to see my face mashed into tomato sauce if that had happened instead?

Maybe it's the ancient steeel T-1. How do the sparks look like? Maybe you can heat treat a sample.

Dude,
lighten up! I was poking at you. Kinda like when we were poking Nick Wheeler to finish his thread.

I'm glad you weren't hurt, didn't realize you were sensitive about it.
Sorry.:foot:
