Wait, what? Steel is harder than titanium?

Well most steels aren't, but there are higher carbon steels that are harder than titanium. I don't think they're used in anything common these days except maybe anvils and blacksmithing tools.

you don't need a high carbon steel, actually, to get a very hard steel. you simply need to heat it between 800-1000C and quench in water. that will give you an incredibly hard, but *very* brittle steel known as martensite

Yeah that'll do it as well.

I highly doubt the rods holding the bracelet together are made of carbide too.

They would likely break when they were being inserted and for a pin to have some "grip" on something it is best if it actually compresses a little (a microscopic amount) during insertion or is swedged.

Time to find out how to coat my bones in tungsten carbide.

Yes, of course, this knowledge is instilled upon birth. Don't be a dick.

i'd rather pick adamantium or unobtanium

Nah, a coating wouldn't do much good. Remove your bones one at a time, use a laser scanner to build a 3D computer model, print one out on a rapid prototype machine, and use that to make a mold pattern. Then you can have the bone cast in solid tungsten carbide.

Of course, given that it's so hard, that actually might be a bad thing. Titanium or stainless steel would offer strength with some flexibility.

As materials get harder, they also become brittle - they can take more stress, but once they get to a certain point, they simply break. More ductile materials can deform slightly without taking permanent damage. If yielding does occur (permanent deformation), then you can get some strain-hardening.

Guess you guys are right, thats just ridiculous.

Wow, he hit that tungsten ring about five times.

The dude can't count...

Also how often do you hit your ring with a knife while wearing it??

What? If you wear a ring all the time it's going to bang and rub up against stuff. What the hell does a knife have to do with anything?

Also use the edit button instead of posting 3 separate times in a row.

Hehe, there was quite a bit of time between them so I hadn't checked the end of the thread.

The knife comment is from one of the other videos by the same dude, buy our rings because they stop bullets and knives...

Edit: I would be much more worried about my fingers than a ring...

Thats only because you don't have the mad reflexes and accuracy to stop a bullet or knife with a thin band of metal.

What I took from the video was that the dude was suggesting that if you slipped while using a knife in the kitchen you wouldn't scratch your nice tungsten carbide ring

The link for the ring stopping a bullet is here

Cliffs -
Texas man decides to work on a handgun.
Puts ammo in the clip and loads the gun...
Then puts the slide back on whilst holding a hand in front of the muzzle...
The slide moves and loads a round and fires it.
The bullet hits his ring finger and deflects into his "pinky"
He loses his pinky but keeps his ring finger.

Point of the story - I don't need mad reflexes or accuracy to not shoot/slice my own hand...

Tungsten Carbide isn't the hardest material that jewlers deal with. Saphire and Diamond are harder. Clearly they are able to cut through these since they have to cut them into the desired shapes, so they sould be able to cut through Tungsten Carbide.

eeee

 

[miketheidiot]

buy a new one, sell the old one

those are used as gemstones though - tungsten carbide is what makes up the ring itself, rather than being seated in a fixture (im not sure if that's the proper term, but you get the idea).

i believe diamonds are laser cut (aside from being cut by other diamonds).

Yeah...I think armor piercing tank shells are made out of tungsten carbide. Good luck.

US military uses depleted uranium these days, at least for the large rounds. I'm not sure what they use for small arms for armor piercing, but I don't think it's tungsten anymore -- not because it isn't good but because of cost. I know the Germans used tungsten for AP rounds in WWII because I'd love to find a few for my Mauser.

Well most steels aren't, but there are higher carbon steels that are harder than titanium. I don't think they're used in anything common these days except maybe anvils and blacksmithing tools.

Armor plating, too.

Have you ever happened to hear of something called "high speed steel"?
